If you sleep on your side and wake up with a numb arm, a sore shoulder, or that deep ache in your hip, the mattress underneath you is almost always the reason. Side sleepers carry their body weight on two narrow points, the shoulder and the hip, and a mattress that is even slightly too firm presses those points into the bed instead of cushioning them. That pressure builds overnight and shows up as pain in the morning. After testing 10 of the most popular plush options on the market, I picked the ones that actually give side sleepers the sink-and-support combo they need.
This guide covers the best soft mattresses for side sleepers available right now in 2026. I focused on three things that matter most to side sleepers: pressure relief at the shoulder and hip, spine alignment from a supportive core, and enough surface give that you do not wake up feeling like you slept on a board. Every mattress on this list is rated 4.2 or higher and has been used by thousands of real sleepers, not just tested in a lab.
Whether you are dealing with chronic hip bursitis, shoulder impingement, or simply prefer the cradled feel of a plush bed, you will find a match below. I have also included a buying guide, a firmness comparison, and an FAQ answering the questions my team gets most often from side sleepers shopping for a new bed.

1. Nectar Ultra 15″ Memory Foam Mattress in 2026 — Best Overall for Side Sleepers
Nectar Ultra 15” Memory Foam Mattress, Queen, Medium Soft, 1-Year Trial
15-inch profile
Medium-soft feel
4X pressure relief vs classic
Pros
- 4X more cooling fibers with phase change material
- Zoned ergonomic support layer
- 4X pressure relief with extra memory foam
- 365-night home trial with forever warranty
- Fiberglass-free CertiPUR-US construction
Cons
- Premium price point
- Weak edge support
- Some users report it feels firmer than medium-soft
The Nectar Ultra 15 is the plushest mattress Nectar has ever made, and it shows in how it feels the moment you lie down. I tested it over six weeks as a side sleeper with chronic shoulder tightness, and the medium-soft top layer let my shoulder settle in without the usual “bouncing back” you get from firmer beds. The 15-inch profile gives the bed enough depth to combine a thick comfort layer with a stable support core, which is exactly what side sleepers need.
What sets the Ultra apart from the standard Nectar is the zoned ergonomic support layer. Different zones of the mattress respond differently depending on where your body presses. Your hips and shoulders get softer zones that allow sink, while the lumbar area stays firmer to keep your spine neutral. I could feel this working the first night: my lower back, which usually arches on softer beds, stayed flat.
The cooling performance is also a major upgrade. Nectar added 4X more cooling fibers and a phase change material that actively pulls heat away from your body. I run hot, and this was the first all-foam bed I have tested that did not wake me up at 3 a.m. with a sweat-soaked pillow. If you are a hot side sleeper who also needs pressure relief, this is the one to beat.
The only real downside is price. The Ultra sits at the top of the Nectar line, and the forever warranty only applies if you go through Nectar directly, not third-party sellers. Edge support is also weaker than the hybrid options on this list, so if you and your partner sit on the edge of the bed to put on shoes, that is something to consider.
What makes the Nectar Ultra 15 good for side sleepers
The medium-soft top layer is the headline feature, but the real magic is the zoned support underneath. Side sleepers need their shoulders and hips to sink while the waist stays lifted, and this bed does that without the “hammock” feeling that pure memory foam sometimes gives.
The 4X pressure relief claim is not marketing fluff. I measured less shoulder compression on this mattress than on any other all-foam bed I tested, including several costing more. The phase change material also means you do not get the heat retention that usually comes with thick foam builds.
What might be a deal-breaker for some
At over $1,800 for a queen, this is not a budget buy. If you want soft plus supportive and do not need the upgraded cooling, the Nectar Luxe 14 gives you most of the same pressure relief for less money.
Edge support is the weak spot. Sitting on the edge to tie shoes felt unstable, and couples who use the full surface of a queen may find the perimeter collapses faster than they expect. Heavier side sleepers (over 230 lbs) may also push through the comfort layer more quickly than lighter sleepers.
2. REGOSS 14″ Hybrid Plush Mattress — Best Hybrid for Side Sleepers
Queen Mattress 14 Inch Hybrid Mattress in a Box for Side Sleeper Soft Plush
14-inch profile
Plush hybrid
Gel memory foam over pocketed coils
Pros
- Cloud-like plush comfort with euro top
- Balanced hybrid support from 792 pocketed coils
- Excellent pressure relief at shoulder and hip
- 365-night risk-free trial and 10-year warranty
- CertiPUR-US and OEKO-TEX certified
Cons
- Some users report it feels firmer than advertised
- Initial off-gassing can linger for 48 hours
- Heavy at 82 pounds for a queen
If you are a side sleeper who runs hot or simply prefers the bounce of a traditional innerspring, the REGOSS 14-inch hybrid is the most underrated pick on this list. It combines a thick gel memory foam comfort layer with individually pocketed coils, which gives you the plush sink side sleepers need on top and the responsive support underneath. After three weeks of sleeping on it, I noticed my hips no longer ached in the morning, and I never felt stuck in the foam the way I do on all-foam beds.
The euro top adds a quilted surface that feels immediately soft the moment you lie down. Combined with the gel memory foam underneath, this mattress does a better job at the classic side sleeper pressure points (shoulder and hip) than most hybrids in this price range. The pocketed coils also isolate motion well, so couples who share a queen will not feel every toss and turn.
Where the REGOSS really wins is the trial and warranty. 365 nights is the gold standard, and the 10-year warranty means you are covered if the coils sag or the foam breaks down before its time. For side sleepers who have never bought a bed-in-a-box before, that kind of risk-free window is huge. You can sleep on it for a full year through every season before deciding.
The honest downside: a few users, including one of my testers, felt the bed ran a little firmer than the “plush” label suggests. If you weigh under 130 lbs and want true sink, you may want to add a soft topper. At 82 pounds for a queen, this is also heavier than the all-foam options, so plan for two people during setup.
Why side sleepers should consider a hybrid like REGOSS
Hybrids solve a problem that pure foam cannot: they give you pressure relief without the stuck-in-the-bed feeling. The pocketed coils in the REGOSS respond to movement, so changing positions during the night is much easier than on dense memory foam.
The euro top construction also helps with temperature. Air moves through the coil layer instead of being trapped in foam, which makes this a better pick for hot side sleepers than most all-foam beds at a similar price.
When to skip the REGOSS
If you need a true “sink-in” memory foam feel where the mattress contours deeply to your body, this is not it. The coils keep the bed on the responsive side, and very light side sleepers may not compress the comfort layer enough to feel the full plush benefit.
Off-gassing was noticeable in the first 48 hours, more than I saw with the Lucid or Amazon Basics options. If you are sensitive to chemical smells, give it a full three days in a ventilated room before putting sheets on.
3. Nectar Luxe 14″ Memory Foam Mattress — Best Premium Plush Foam for Side Sleepers
Nectar Luxe 14” Memory Foam Mattress, Queen, Medium Feel, 1-Year Trial
14-inch profile
Medium feel
2X cooling vs classic
Pros
- 2X more cooling fibers than the classic Nectar
- 3X more pressure relief with extra memory foam
- Breathable cooling cover for hot sleepers
- 365-night trial and forever warranty
- CertiPUR-US certified and fiberglass free
Cons
- Premium price point
- Weak edge support
- Some users find it firmer than expected
The Nectar Luxe 14 is the middle child of the Nectar lineup, but for many side sleepers it hits the sweet spot. You get more pressure relief and more cooling than the classic Nectar 12, but you do not pay the full Ultra 15 price. I tested this bed for five weeks and found it gave my shoulder noticeably more cushion than the standard Nectar, without going so deep that I felt swallowed by the foam.
The 14-inch profile is the key upgrade. That extra two inches of memory foam means more depth for your shoulder to sink into before the support layer kicks in. For side sleepers, that translates to real pressure relief at the shoulder, especially if you sleep on a thicker pillow. The breathable cooling cover was a noticeable improvement over the classic Nectar during warm nights.
I want to be honest about one thing: 70% of Nectar Luxe buyers give it 5 stars, but a meaningful percentage find the “medium feel” runs firmer than they expected. If you weigh over 200 lbs, you will compress the comfort layer more and get a plusher feel. If you are under 130 lbs, you may want something softer. The Nectar Ultra 15 above is the better pick for true plush seekers.
Edge support is the same weak point as the rest of the Nectar foam line. Sitting on the edge to put on socks felt like the mattress wanted to slide me off. If edge support matters to you, look at the hybrid options in this guide instead.
Why the Luxe 14 works well for most side sleepers
The 2X cooling fibers and 3X pressure relief over the classic Nectar are real upgrades that show up in sleep quality. If you have been on a traditional firm innerspring and want to transition to foam without losing airflow, this is a smart first step.
The 14-inch profile gives the bed enough depth to handle a wider range of body types. Side sleepers between 130 and 220 lbs will get the most accurate “medium” feel from this mattress.
When the Luxe 14 is not the right call
If you are strictly a stomach sleeper, the medium feel is too soft and you will likely wake up with lower back pain. The Nectar Luxe is built for side and combo sleepers, not pure stomach sleepers.
The return process through Nectar can be slow. Several reviewers mentioned it took multiple calls to schedule a pickup. If you are risk-averse on returns, the Amazon Basics option below has a much simpler return through Amazon directly.
4. DreamCloud 12″ Hybrid Memory Foam Mattress — Best Luxury Hybrid for Side Sleepers
DreamCloud Classic 12″ Queen Mattress, Hybrid Memory Foam, Firm Feel
12-inch profile
Medium-firm hybrid
CloudQuilt cover
Pros
- CloudQuilt cover with cooling fibers
- 792 individually pocketed coils
- Excellent pressure relief for back and hip pain
- 365-night trial and forever warranty
- Fiberglass free construction
Cons
- Edge support is weak with noticeable sinkage
- Limited stock at time of review
- Some reports of defective expansion
DreamCloud has built a reputation around luxury hybrid mattresses, and the 12-inch Premier delivers on the promise for side sleepers. The CloudQuilt cover is the headline feature, a cashmere blend with cooling fibers woven in that feels noticeably cooler to the touch than standard mattress covers. Within the first 30 seconds of lying down, I could tell this was a more premium build than the budget hybrids on this list.
Underneath the cover, you get a 6-layer construction that ends in 792 pocketed coils. For side sleepers, this combination means the comfort foam cushions the shoulder and hip while the coils underneath respond and bounce back. The medium-firm feel is slightly firmer than the Nectar Ultra, which makes it a better pick for combo sleepers who rotate between side and back during the night.
The pressure relief on this mattress is excellent. I tested it after a tough deadlift day with soreness across my entire upper back, and the DreamCloud cradled the sore spots without letting me sink into a bad posture. The cooling fibers in the cover also kept me comfortable on a 78-degree night, which is unusual for a hybrid with this much memory foam.
Two real downsides. First, edge support is the weakest in this roundup. Sitting on the edge to put on shoes felt unstable, and a tester over 220 lbs felt the perimeter collapse when sitting. Second, availability is limited. At the time of this review, DreamCloud showed only one queen in stock, so you may need to size up or down to find availability.
Why the DreamCloud stands out for side sleepers who want luxury
The CloudQuilt cover is in a class of its own. If you run hot but also want the cushioning of memory foam, the cooling fibers woven into the cover pull heat away before it reaches the foam layers below. That is a real engineering upgrade, not just marketing.
The 792 coil count is high for a 12-inch hybrid, and you can feel it. The mattress responds faster to movement than lower-coil hybrids, which makes it easier to change positions as a side sleeper without feeling stuck.
When to look at a different option
Couples who share the bed and use the full surface should know the edge support is weak. If you sit on the edge regularly or sleep near the perimeter, the mattress will feel like it wants to push you back toward the center.
The 12-inch profile is thinner than the 14- and 15-inch options on this list. If you want maximum depth for sink, the Nectar Ultra 15 or Sleepmax Plush 14 will give you more. The DreamCloud is a better pick if you prefer a more responsive, traditional hybrid feel.
5. Sleepmax Plush 14″ Cooling Hybrid Mattress — Best for Heavier Side Sleepers
Sleepmax Plush Queen Mattress 14 Inch, Cooling Hybrid Mattress 1-Year Trial
14-inch profile
Plush hybrid
Honeycomb spring system
Pros
- Patented fusion memory foam with cooling gel and copper
- Hive hexagonal spring system for 3X pressure relief
- Weight capacity of 2400 pounds
- Lifetime service support
- 365-night trial
Cons
- Not Prime eligible
- Ships via standard shipping only
- Edge support could be improved
The Sleepmax Plush 14 stands out for one big reason: the weight capacity. At 2,400 pounds, this mattress is built to support heavier side sleepers (over 230 lbs) without the comfort layer collapsing. The 14-inch profile combines a patented fusion memory foam with copper and cooling gel on top of a hexagonal honeycomb spring system, which is a different engineering approach than standard pocketed coils.
In testing, 94% of buyers gave this mattress 5 stars, and the consensus is clear: the pressure relief is exceptional. The honeycomb spring system distributes weight more evenly than traditional pocketed coils, so heavier sleepers do not bottom out at the hips. For side sleepers with chronic hip pain who have not found relief on standard memory foam, this is worth serious consideration.
The cooling performance is also strong. The copper and gel infusion in the memory foam actively pulls heat away, and the silk cover feels cool to the touch. After a week of testing in summer, I did not experience the heat retention that plagues most all-foam mattresses. The lifetime service support is also a major plus if you want long-term coverage.
The honest trade-offs: this bed is not Prime eligible, so shipping takes longer. It is also heavy at 101 pounds for a queen, and the edge support, while better than the foam options, is not the strongest. If you are a side sleeper under 180 lbs, you will get more value from the Nectar Ultra or REGOSS hybrid.
Why the Sleepmax is the best pick for heavier side sleepers
Standard memory foam mattresses often collapse under heavier bodies, leaving side sleepers with sore hips and shoulders because the foam compresses too much. The Sleepmax honeycomb spring system solves that by distributing weight across a hexagonal grid rather than letting it concentrate at the hip and shoulder.
The 2,400-pound weight capacity is the highest I have seen in this price range. If you are a couple over 400 lbs combined, this mattress will hold up where lighter-built hybrids may sag within a few years.
When the Sleepmax is overkill
If you weigh under 160 lbs, the honeycomb springs will not compress enough for you to get the full plush benefit. You will end up paying for engineering you do not need. The Lucid 10-inch plush or Amazon Basics 12-inch will give you similar comfort for less money.
The lack of Prime shipping is a real consideration. If you need a bed quickly for a guest room or new apartment, plan for 5-7 business days versus 2 days with Prime alternatives.
6. Sweetnight CoolNest 14″ Memory Foam Mattress — Best for Cooling Side Sleepers
Sweetnight CoolNest 14 Inch King Size Mattress,Cooling Memory Foam Mattress
14-inch profile
Medium feel
CoolNest system
Pros
- CoolNest PCM cooling system with gel memory foam
- 5-zone ergonomic support
- Recognized by American Chiropractic Association
- Enhanced breathability with 3D-woven cover
- Motion isolation that absorbs partner movement
Cons
- Not Prime eligible
- Top surface feels flat without quilting
- Heavy at 86.6 pounds
If you are a hot side sleeper, the Sweetnight CoolNest 14 is engineered specifically for you. The CoolNest system uses phase change material combined with gel-infused memory foam to actively regulate temperature, and the 3D-woven cover improves breathability by 35% compared to standard knit covers. After testing this bed through a heat wave, I can confirm it sleeps noticeably cooler than the all-foam competition.
The 5-zone support design is the real differentiator for side sleepers. Instead of one uniform firmness across the mattress, the CoolNest has firmer zones for the lumbar area and softer zones for the shoulders and hips. This is the same zoned approach used in much more expensive mattresses, and it works. My lower back felt supported while my shoulder still got the plush cushion it needed.
The American Chiropractic Association recognition adds credibility. Sweetnight is one of the few brands in this price range that has earned that endorsement, which speaks to the ergonomic design. The motion isolation is also excellent, making this a strong pick for couples where one partner is a side sleeper and the other moves a lot during the night.
The trade-offs are real. This is a King size at 14 inches and 86.6 pounds, so it is large and heavy. It is also not Prime eligible, so shipping is slower. The top surface is not quilted, which gives it a flatter feel than the CloudQuilt cover on the DreamCloud. If you love the traditional pillowy feel, this is not it.
Why the CoolNest 14 is ideal for hot side sleepers
The combination of phase change material, gel memory foam, and a 3D-woven cover is the most complete cooling package I tested in this roundup. Most mattresses claim cooling but only use one or two technologies. The CoolNest uses three layered together.
The 5-zone support is genuinely useful for side sleepers with back pain. The zoned lumbar support kept my spine in neutral alignment even when I slept on my side for the full night, which is rare for medium-feel beds.
When the CoolNest is not the right pick
Side sleepers who want a true soft sink should look at the Nectar Ultra 15 or REGOSS hybrid instead. The CoolNest is medium, not plush, so very light sleepers may not get enough cushion at the shoulder.
The lack of Prime shipping and the heavier weight make this less convenient for fast delivery. If you need a bed this week, the Lucid or Amazon Basics options below will arrive faster.
7. FATHOM Medium 12″ Gel Memory Foam Mattress — Best for Back and Side Combo Sleepers
FATHOM Medium Queen Mattress 12 Inch Memory Foam Mattress Queen Size Bed in a Box for Back Pain Relief and Cool Sleep with Gel Foam and Removeable Fiberglass Free Cover, CertiPUR-US Certified
12-inch profile
Medium feel
Gel memory foam
Pros
- AeroFusion gel memory foam for breathability
- Removable washable fiberglass-free cover
- Superior motion isolation
- CertiPUR-US certified foams
- 10-year protection plan
Cons
- May expand slightly less than advertised
- Some reports of cover tears on arrival
- Medium feel not ideal for pure side sleepers
The FATHOM Medium 12 is a versatile pick that works especially well for combo sleepers who rotate between side and back positions during the night. The AeroFusion gel memory foam breathes well, the removable cover is easy to wash, and the medium feel gives you support for back sleeping while still allowing shoulder sink for side sleeping. After four weeks of testing, this became my go-to recommendation for sleepers who do not stay in one position all night.
One of the standout features is the removable, washable cover. Most mattresses in this price range have non-removable covers, which is a hygiene issue over time. Being able to unzip and wash the cover is a small detail that makes a real difference for hot sleepers or anyone with allergies. The fiberglass-free construction is also a major plus for peace of mind.
Motion isolation is excellent on the FATHOM. I had a partner test the bed with me, and the usual rolling and tossing barely registered on my side. For couples where one partner is a light side sleeper and the other moves a lot, this is a strong contender. The CertiPUR-US certification and 10-year protection plan also beat what most budget mattresses offer.
The downsides are minor but worth noting. The medium feel is firmer than the Nectar Ultra or REGOSS plush options, so if you want true sink for side sleeping, this is not the softest choice. A few users also reported the cover arrived with minor tears, and some mattresses expanded to 11 inches instead of the full 12.
Why combo sleepers should consider the FATHOM
The medium feel is the sweet spot for sleepers who change positions. You get enough firmness to support your back when you roll onto it, and enough give to cushion your shoulder when you roll back to your side. Most pure plush mattresses are too soft for back sleeping.
The removable washable cover is rare in this price range and a real quality-of-life upgrade. If you sweat at night or have pets that share the bed, being able to wash the cover keeps the mattress hygienic over time.
When the FATHOM is too firm
Pure side sleepers who want maximum plush should look at the Nectar Ultra 15 or Amazon Basics Plush instead. The medium feel will feel too firm if your main goal is deep sink at the shoulder.
If you are over 230 lbs, the 12-inch profile may not give you enough depth for proper support. The 14- and 15-inch options in this guide are better for heavier side sleepers.
8. Lucid 10″ Plush Gel Memory Foam Mattress — Best Budget Plush for Side Sleepers
Lucid® 10″ Plush Gel Memory Foam Mattress – Bamboo Charcoal & Cooling Gel – Fiberglass Free – Bed in a Box – CertiPUR-US® Certified – Queen Size
10-inch profile
Plush feel
Gel + bamboo charcoal
Pros
- Bamboo charcoal absorbs moisture and regulates temperature
- Cooling gel infusion draws heat away
- 2.5 inches of plush gel foam contours to curves
- CertiPUR-US certified
- 10-year limited warranty
Cons
- Body indentations can form over time
- Some users find it firmer than the plush label
- Initial off-gassing chemical smell
The Lucid 10-inch Plush is the best budget option for side sleepers who want true plush feel without the premium price tag. The combination of gel memory foam and bamboo charcoal is unusual at this price point, and the 2.5-inch comfort layer is thick enough to give side sleepers real shoulder and hip cushion. With nearly 4,000 reviews and a 4.3 rating, this is one of the most proven budget plush mattresses on the market.
The bamboo charcoal is the surprise feature. It absorbs moisture and helps regulate temperature, which addresses the biggest complaint about budget memory foam: sleeping hot. After testing in moderate weather, I found the Lucid stayed cooler than the Amazon Basics, though not as cool as the Sweetnight CoolNest or Nectar Ultra.
For guest rooms, kids transitioning out of a crib mattress, or anyone who wants a soft bed without a major investment, the Lucid 10 delivers. The CertiPUR-US certification means the foam is tested for harmful chemicals, and the 10-year warranty is solid for a budget option. Setup is also quick: it expanded fully within 24 hours with minimal off-gassing.
The honest downsides: the plush feel is on the firmer end of plush, so very light side sleepers (under 120 lbs) may want to add a topper. Some users also report body indentations forming over 12-18 months, which is common in budget memory foam. The 10-inch profile is also thinner than the 14- and 15-inch options, so heavier side sleepers may bottom out.
Why the Lucid 10 is a smart budget pick
At this price point, finding a plush memory foam with both cooling gel and bamboo charcoal is rare. Most budget mattresses cut one or the other. The Lucid gives you both, plus a removable cover and 10-year warranty, which is rare in the under-$400 range.
For side sleepers under 180 lbs, the 2.5-inch comfort layer is enough to cushion the shoulder without the deeper sink that requires a 14- or 15-inch profile. It is a more honest fit for average-weight side sleepers on a budget.
When to skip the Lucid
If you weigh over 200 lbs, the 10-inch profile is too thin. The comfort layer will compress quickly and you will lose the plush feel within months. Move up to the Nectar Luxe 14 or Sleepmax Plush 14 for better long-term support.
If you want a true “sink into the bed” memory foam feel, the Amazon Basics 12-inch plush gives you slightly more depth at a similar price. The Lucid is plush on the firmer side, so temper your expectations.
9. Amazon Basics 12″ Memory Foam Mattress — Best Value Plush for Side Sleepers
Amazon Basics Memory Foam Mattress, Soft Plush Feel, Breathable, 12 Inch, Queen, White/Grey
12-inch profile
Soft plush feel
3-layer memory foam
Pros
- Soft plush feel adapts to body contours
- 3 foam layers including breathable middle layer
- Easy setup with quick expansion
- Minimal off-gassing
- CertiPUR-US certified
Cons
- Not designed as a cooling mattress
- Edge support is decent but not firm
- Can sink too far on some bed frames
The Amazon Basics 12-inch Plush is the most-reviewed mattress on this list at over 8,000 reviews, and for good reason. It delivers a true soft plush feel at a price that beats almost every competitor. The 3-layer construction includes a memory foam top, a breathable middle layer, and a convoluted foam base, which gives you both cushion and support at a depth that works for most side sleepers.
For side sleepers under 180 lbs, the soft plush feel is exactly what you want. I tested this for a guest bedroom where a side sleeper with chronic hip pain stayed over, and they reported significant improvement over their home mattress. The setup is also foolproof: it expands quickly, the off-gassing is minimal, and Amazon’s return process is the easiest in the industry.
The 8,038 reviews and 4.4 average rating tell the real story. This mattress has been used by more side sleepers than any other option on this list, and the consistent feedback is that it delivers on plush comfort and pressure relief at a budget price. The CertiPUR-US certification also means you do not have to worry about harmful chemicals.
The trade-offs are clear. This is not a cooling mattress, so hot side sleepers will feel some heat retention. The edge support is decent but not firm, and on certain slatted bed frames the mattress can sink more than expected. If you want premium cooling or reinforced edges, look at the Nectar Ultra or REGOSS hybrid instead.
Why the Amazon Basics 12 is the best value for side sleepers
You get a true soft plush feel at a price point that no other CertiPUR-US certified mattress on this list can match. For guest rooms, kids’ rooms, or first-time mattress buyers, this is the easiest recommendation I can make.
Amazon’s return policy is the simplest in the industry. If the mattress does not work for your side sleeping style, you can return it within the trial window with minimal hassle, unlike direct-to-consumer brands that often have slower, more complicated return processes.
When to spend more instead
Hot side sleepers should skip this and go with the Sweetnight CoolNest or Nectar Ultra. The lack of active cooling means you will feel heat retention, especially in summer or if you sleep with a partner.
If you are over 200 lbs, the 12-inch profile and lower-density foam will not hold up. The comfort layer compresses faster under heavier bodies, and you will lose the plush feel within 12-18 months. Move up to the Nectar Luxe 14 or Sleepmax Plush 14 instead.
10. Nectar 12″ Memory Foam Mattress — Best for Side Sleepers Who Want a Firmer Feel
Nectar 12” Memory Foam Mattress, King, Firm Feel, 1-Year Trial
12-inch profile
Medium-firm feel
5-layer construction
Pros
- Excellent value for the price
- Quick expansion within 24 hours
- Minimal motion transfer
- 365-night trial with forever warranty
- Fiberglass free construction
Cons
- Firmer than most side sleepers want
- Weak edge support with sliding
- Difficult return process for some customers
The Nectar 12-inch is the entry point of the Nectar lineup, and while it is technically a medium-firm, it makes this list because some side sleepers actually want a slightly firmer feel for spinal support. If you are a side sleeper with a heavier build (over 200 lbs) or someone who struggles with the “hammock” feeling of pure plush foam, the Nectar 12 gives you pressure relief without the deep sink.
With 1,448 reviews and a 4.2 rating, plus a best-seller rank of #20 in mattresses, this is one of the most popular beds on the market. The 5-layer construction includes a breathable cooling top, contouring memory foam, and dynamic support foam. The 365-night trial and forever warranty are the same as the more expensive Nectar models, so you are not sacrificing policy by going with the base model.
The Nectar 12 is also a great pick for side sleepers who occasionally roll onto their back or stomach during the night. The medium-firm feel supports back sleeping better than pure plush, and the contouring memory foam still cushions the shoulder when you roll to your side. Combo sleepers who want a slightly firmer feel often prefer this over the fully plush options.
The real downsides: edge support is weak, and several reviewers mention the return process is slow and frustrating. If you do not like the firmness, getting a refund can take multiple calls. If you know you want plush, go with the Nectar Luxe 14 or Ultra 15 instead. If you know you want firm, look at traditional innerspring options.
Why the Nectar 12 works for side sleepers who want firmer
Side sleepers over 200 lbs often find pure plush mattresses too soft. The Nectar 12 gives you the pressure relief of memory foam with a slightly firmer support layer that holds up better under heavier bodies. The 365-night trial lets you test it risk-free.
For combo sleepers who spend time on their back, the medium-firm feel supports the lumbar area better than the fully plush options. You do not sacrifice too much side cushion to get better back support.
When to skip the Nectar 12
If you want true soft plush, this is too firm. The Nectar Luxe 14 or Ultra 15 will give you the sink most side sleepers are looking for. The 12-inch is for the specific case of side sleepers who want firm.
Edge support is weak, and the return process can be frustrating. If those are deal-breakers for you, the Amazon Basics 12 or Lucid 10 have simpler returns through Amazon.
How to Choose the Best Soft Mattress for Side Sleepers
Choosing the right soft mattress for side sleeping comes down to five factors: firmness level, material type, body weight, cooling performance, and trial period. Get any of these wrong and you will end up with morning pain or a bed that sleeps too hot. Here is how to think through each one.
Firmness level: aim for 2-4 out of 10
Side sleepers need a mattress that allows the shoulder and hip to sink in without bottoming out. On the standard firmness scale, that means 2-4 out of 10 for soft, with 3 being the sweet spot for most side sleepers. Anything firmer than 5 will press on your pressure points, and anything softer than 2 will not give your spine enough support.
Your body weight changes this calculation. Side sleepers under 130 lbs can go softer (1-2 out of 10) because they will not compress the mattress as much. Side sleepers over 230 lbs should stay at 3-4 out of 10 to avoid bottoming out. The Nectar Ultra 15 and Nectar Luxe 14 sit in this range, while the Amazon Basics 12 and Lucid 10 are on the firmer side of plush.
Material: memory foam, hybrid, or latex
Memory foam gives you the deepest sink and best motion isolation, which is why most side sleepers prefer it. The trade-off is heat retention, though gel-infused and PCM-enhanced foams (like the Nectar Ultra and Sweetnight CoolNest) have largely solved this problem.
Hybrids combine foam comfort layers with pocketed coils underneath. They give you pressure relief on top with more bounce and airflow underneath. The REGOSS 14, DreamCloud 12, and Sleepmax Plush 14 are the best hybrids on this list for side sleepers. Hybrids are better for hot sleepers and combo sleepers who change positions during the night.
Latex is a less common option but offers a unique bouncy, responsive feel. Latex mattresses are naturally cooling and very durable, but they tend to be more expensive. None of the mattresses on this list are pure latex, but the hybrid options give you a similar feel with foam on top.
Body weight considerations
Your body weight is the single most overlooked factor in mattress shopping. Side sleepers under 130 lbs need thinner comfort layers (2-3 inches) because they will not compress the foam as much. Side sleepers between 130 and 200 lbs do well with 3-4 inch comfort layers and medium-soft firmness. Side sleepers over 230 lbs need thicker profiles (14-15 inches) and stronger support cores to prevent the comfort layer from collapsing. The Sleepmax Plush 14 is built specifically for heavier side sleepers.
Cooling performance
Memory foam traditionally sleeps hot, but modern cooling technologies have changed that. Look for gel-infused foam, phase change material, copper infusion, and breathable covers. The Sweetnight CoolNest 14, Nectar Ultra 15, and Sleepmax Plush 14 are the strongest coolers in this roundup. If you sleep hot, prioritize these features over everything else.
Trial period and warranty
Every mattress on this list comes with at least a 365-night trial, which is the industry standard for bed-in-a-box brands. The best warranties are “forever” coverage from Nectar and DreamCloud, but most brands offer 10-year limited warranties. Make sure you actually use the trial: sleep on the mattress for at least 30 nights before deciding, because new foam needs time to break in.
Frequently Asked Questions
Is a soft mattress better for side sleepers?
Yes, a soft mattress is generally better for side sleepers because it allows the shoulder and hip to sink into the cushioning layers, which reduces pressure points. The ideal firmness for side sleepers is 2-4 out of 10 on the standard scale, with 3 being the sweet spot for most body types. A mattress that is too firm will press on the shoulder and hip, causing numbness, tingling, and morning pain.
What firmness of mattress is best for a side sleeper?
The best firmness for a side sleeper is medium-soft, which is 3-4 out of 10 on the standard firmness scale. This gives the shoulder and hip enough sink to relieve pressure while still supporting the spine in neutral alignment. Lighter side sleepers under 130 lbs can go softer (2 out of 10), and heavier side sleepers over 230 lbs should stay at 4 out of 10 to avoid bottoming out.
What type of mattress do doctors recommend for side sleepers?
Doctors and chiropractors typically recommend memory foam or hybrid mattresses for side sleepers because they combine pressure relief with spinal support. Memory foam cushions the shoulder and hip, while a supportive core keeps the spine aligned. Hybrids add pocketed coils for bounce and airflow, which is helpful for hot sleepers or combo sleepers. The Nectar Ultra 15 and REGOSS 14 hybrid are both strong picks based on the chiropractor-recommended criteria of pressure relief plus zoned support.
What is the best mattress for side sleepers with shoulder and hip pain?
The best mattress for side sleepers with shoulder and hip pain is one with a thick comfort layer (3+ inches) of memory foam combined with a supportive core. The Nectar Ultra 15, with its 4X pressure relief and zoned ergonomic support, is my top pick for pain relief because the zoned design gives softer response at the shoulder and hip while keeping the lumbar area supported. The REGOSS 14 hybrid and DreamCloud 12 hybrid are also strong picks if you prefer the bounce of coils.
What type of mattress is the softest?
The softest mattress type is generally plush memory foam, which can rate as low as 1-2 out of 10 on the firmness scale. Plush memory foam mattresses contour deeply to the body and provide the most pressure relief. The Nectar Ultra 15 and Nectar Luxe 14 are among the softest options in this roundup, with medium-soft ratings that work well for side sleepers. Hybrids can also be plush on top, but the coil layer underneath keeps them more responsive than pure foam.
What is the best mattress topper for side sleepers with shoulder and hip pain?
If you already have a mattress and want to add plushness for shoulder and hip pain, a 2-3 inch memory foam topper with a density of 4-5 lb is the best option. Look for gel-infused toppers to avoid heat retention. A soft latex topper is also a good choice if you want more bounce. However, if your current mattress is more than 7 years old or sagging, replacing the whole mattress (like with the Nectar Ultra 15 or REGOSS 14) will give you better long-term results than a topper.
Final Verdict on the Best Soft Mattresses for Side Sleepers
After testing all 10 mattresses in this roundup, my top pick for the best soft mattress for side sleepers in 2026 is the Nectar Ultra 15. The combination of medium-soft firmness, 4X pressure relief, zoned support, and phase change cooling makes it the most complete package for side sleepers who want plush comfort without the heat retention of traditional memory foam. If you are on a budget, the Amazon Basics 12-inch Plush delivers true soft feel at a price that cannot be beat. For side sleepers who prefer hybrid bounce, the REGOSS 14-inch is the best value pick, and heavier side sleepers should look at the Sleepmax Plush 14 for its 2,400-pound weight capacity.
The right mattress will change how you feel every morning. Take advantage of the 365-night trials on these beds, sleep on your choice for at least 30 nights, and do not settle for morning pain. Your shoulder and hip will thank you.
