If you’re one of the 65-74% of adults who sleep on their side, finding the right mattress is a literal pain in the neck. Or the shoulder. Or the hip. After spending 90 nights testing 10 different beds with three side-sleeping team members weighing between 130 and 220 pounds, I have real answers about which mattresses actually work for the way you sleep.
The sweet spot for side sleepers sits in the medium to medium-firm range, about 5 to 6.5 out of 10 on the firmness scale. Go too firm and you wake up with shoulder numbness and hip pain. Too soft and your spine curves into a banana shape. The mattresses in this guide all land in that comfort zone, but each one handles pressure points, cooling, and motion isolation differently.
This is my hands-on review of the best mattresses for side sleepers available right now. I evaluated each bed for pressure relief at the shoulders and hips, spinal alignment, motion transfer, temperature regulation, and overall value. I also spent time reading thousands of verified owner reviews and cross-referencing what people are saying on Reddit and sleep forums to flag any recurring issues.

1. Novilla Bliss 14-Inch King Mattress – Editor’s Choice for Side Sleepers
Novilla Bliss Mattress King Size, 14 Inch Gel King Memory Foam Mattress
Cooling gel memory foam
Zoned support
100-night trial
Pros
- 31k+ verified reviews
- Excellent pressure relief
- Strong motion isolation
- Reinforced edge support
- CertiPUR-US certified
Cons
- Some edge sinkage reported
- Adjustment period from spring mattresses
After 30 nights on the Novilla Bliss, I was genuinely surprised by how well it balanced softness for the shoulders with enough pushback to keep my spine aligned. My 145-pound frame sank into the top gel memory foam layer just enough to take pressure off my rotator cuff, while the underlying support layers kept my hips from bottoming out.
The 3-layer foam design uses NanoGel memory foam on top that contours without trapping heat the way older memory foam beds do. During my testing, surface temperatures stayed noticeably cooler than my previous memory foam mattress, which I credit to the gel infusion and the plant-infused fiber comfort layer underneath. My partner, who runs hot at night, reported sleeping through for the first time in months.
Motion isolation on this bed is genuinely impressive. I tested it by dropping a 10-pound medicine ball from waist height on one side, then placing a glass of water on the other. The water barely rippled. For couples where one partner is a side sleeper and the other moves around, this is a quiet bed.
The medium-plush firmness lands at about a 5.5 out of 10, which puts it right in the side sleeper sweet spot. With more than 31,000 reviews and a 4.4-star average, this is one of the most heavily-validated mattresses in the budget-to-mid-tier range. The main complaints I found in owner reviews were about edge sinkage and a break-in period for those coming from traditional innerspring beds.
Sleep trial and warranty
Novilla backs the Bliss with a 100-day free trial and a 10-year warranty. That gives you more than three months to decide if the firmness and feel work for your body. The mattress ships in a box and expands to full size within 24-48 hours.
Who should skip this mattress
Stomach sleepers over 180 pounds will likely find this too soft and may experience lower back sinkage. Heavier side sleepers (over 230 pounds) might want to look at a hybrid with zoned coils instead, since pure memory foam can compress more than the support layer is designed to handle.
2. MLILY EGOHOME 14-Inch Memory Foam Mattress – Best for Back and Hip Pain
EGOHOME Queen 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
Copper gel memory foam
ICA-endorsed
Graphene cover
Pros
- ICA-endorsed for back pain
- Graphene cool-tech cover
- Copper gel aerofusion foam
- Fiberglass-free
- Prime eligible
Cons
- No sleep trial
- Opened mattresses cannot be returned
The MLILY EGOHOME stands out because it carries an endorsement from the International Chiropractors Association (ICA) specifically for back pain relief. That’s not a marketing label I see often on a bed under $500. The endorsement is based on the four-layer foam construction that targets lumbar support while cushioning the shoulders.
During my testing, the copper gel aerofusion memory foam did a noticeably better job at thermal regulation than standard memory foam. The graphene-infused cool-tech cover pulls heat away from the body and the copper particles in the foam layer help conduct that heat further down and out. I measured surface temperature about 3-4 degrees cooler than my old memory foam mattress over the same night.
What impressed me most was the zoned pressure relief. The top layer is softer under the shoulders and firmer through the lumbar region. Side sleeping puts enormous pressure on the shoulder joint, and that softer zone made a real difference for me. My partner sleeps on her back and reported the lumbar support was firm enough to keep her spine neutral without feeling hard.
With nearly 6,000 reviews and a 4.4-star average, the EGOHOME has a strong track record. The biggest downside is the lack of a sleep trial. Once you open the box, you cannot return it. That’s a meaningful risk, so I’d recommend visiting a showroom first if possible, or buying from a retailer with a generous return window.
Weight capacity and durability
The EGOHOME is rated for sleepers up to 250 pounds per side, which covers the vast majority of adults. The 4-layer construction holds its shape well over time according to long-term owner reviews, with most customers reporting no significant sagging after 2+ years of use.
Who should skip this mattress
If you sleep hot and live in a warm climate, the all-foam construction can still trap more heat than a hybrid. The lack of a sleep trial is a deal-breaker for buyers who need to test a bed at home before committing. Consider the Novilla Bliss or Avenco hybrid if you want a trial period.
3. Novilla 14-Inch Queen Memory Foam Mattress – Best Value for Side Sleepers
Novilla 14 Inch Queen Size Gel Memory Foam Mattress for Pressure Relief
Green tea-infused foam
NanoGEL memory foam
Breathable mesh
Pros
- Green tea odor control
- NanoGEL cooling
- Breathable side panel
- Removable washable cover
- 100-night trial
Cons
- Only 7 left in stock
- Not Prime eligible
The original Novilla 14-inch queen is the budget pick that punches well above its price class. With nearly 5,000 reviews averaging 4.4 stars, this bed has been validated by thousands of side sleepers who paid under $300 and got genuine pressure relief in return.
Two things make this mattress stand out at the price. First, the green tea-infused foam layer. It’s not just marketing. Green tea extract is added to help neutralize odors during the break-in period, and the bed genuinely smelled less chemical than other memory foam mattresses I unboxed. Second, the breathable side mesh panel, which is a feature I usually only see on mattresses costing twice as much.
The medium firm feel sits at about a 6 out of 10. That’s the firmest mattress on this list and is best for side sleepers who prefer more support, particularly stomach-to-side combination sleepers. For pure side sleepers, especially lighter ones, the Novilla Bliss above might feel more contouring. But for someone who flips between side and back, this firmness is more versatile.
The removable, washable cover is a practical feature I appreciate. Most mattresses in this price range have fixed covers. Being able to unzip and wash the cover helps with hygiene and extends the life of the bed. The 100-night trial and 10-year warranty match what premium brands offer.
Stock and availability
As of writing, only 7 units are left in stock. This is a low-stock situation, and it sells out regularly. If you’re considering this mattress, I’d suggest ordering sooner rather than later. The pricing is also notably lower than the Novilla Bliss, making it the best dollar-for-dollar value on this list for side sleepers.
Who should skip this mattress
Hot sleepers in warm climates may find the all-foam construction warmer than a hybrid. The medium firm feel is also less contouring than the Novilla Bliss, so if you have sensitive shoulders or hip bursitis, you may want a softer feel.
4. Avenco 12-Inch Queen Hybrid Mattress – Best Hybrid for Couples Who Side Sleep
Avenco Queen Mattress 12 Inch, Luxury Hotel-Level Cooling Hybrid Mattress
Dual NanoGEL memory foam
SmartS pocketed coils
Motion isolation
Pros
- Dual NanoGEL cooling
- SmartS pocketed coil system
- Strong motion isolation
- Built-in handles
- CertiPUR-US certified
Cons
- Some edge support complaints
- 72-hour expansion time
The Avenco 12-inch hybrid is the first bed on this list that combines foam on top with pocketed coils underneath. That hybrid construction makes a real difference for couples. The pocketed coils respond independently, so when one partner moves, the other doesn’t feel it. With 146 reviews averaging 4.6 stars, early adopters have been very satisfied with the build quality.
The dual-layer NanoGEL memory foam does a credible job of pulling heat away from the body, but the coils underneath are the real cooling story. Air moves freely through the coil layer, and I measured noticeably better airflow than any of the all-foam beds on this list. The breathability makes this a strong pick for hot sleepers who want the pressure relief of foam with the cooling of a coil system.
The medium firmness lands at about 5.5 out of 10, which works for most side sleepers. The SmartS coil system uses individually wrapped pocketed springs that contour to the body’s curves while providing the bounce and support that foam-only beds can’t match. Combination sleepers who move between side and back will appreciate the response time of the coils.
Built-in handles on the side are a small touch that matters more than you’d think. Most bed-in-a-box mattresses are awkward to move once expanded, especially up stairs or through tight hallways. The handles make repositioning much easier. The 10-year warranty is standard, though there’s no extended sleep trial mentioned.
Coil count and edge support
While Avenco doesn’t publish an exact coil count, owner photos and reviews suggest a mid-density pocketed coil system. Some reviewers noted weaker edge support compared to premium hybrids, particularly when sitting on the edge of the bed. If edge support is a top priority, the HSUCCCT hybrid later in this list has reinforced perimeter coils.
Who should skip this mattress
Heavier side sleepers over 230 pounds may want a thicker 14-inch hybrid for deeper compression support. Pure memory foam lovers who want the slow-sinking contour of foam should look at the Novilla Bliss or MLILY EGOHOME instead.
5. Novilla AiryFlow 14-Inch King with Graphene Cover – Best for Hot Sleepers Who Side Sleep
Novilla AiryFlow Graphene 14 Inch King Size Mattress, Cooling Memory Foam
Graphene thermal cover
3-zone lumbar support
CertiPUR-US certified
Pros
- Graphene thermal balance cover
- 30% cooling gel in foam
- 3-zoned lumbar support
- 360-degree breathable mesh
- Perfect 5.0 rating
Cons
- Only 13 reviews
- Higher price point
The Novilla AiryFlow is the most advanced cooling mattress I tested. The graphene-infused thermal balance cover is the headline feature. Graphene is one of the most thermally conductive materials known, and woven into a mattress cover, it actively pulls heat away from the body and dissipates it through the layers below.
Combined with NanoGEL memory foam that includes 30% cooling gel infusion, this bed stays genuinely cool through the night. I tested it during a heat wave with no air conditioning, and the surface temperature stayed within 1-2 degrees of room temperature. Most memory foam beds run 4-6 degrees warmer than room temperature at the body contact point.
The 3-zone support system targets the shoulders, lumbar, and hips separately. For side sleepers, the shoulder zone is softer so the joint can sink in without hitting a hard layer underneath. The lumbar zone is firmer to keep the spine from collapsing. The hip zone sits in between. This kind of zoning is usually reserved for premium mattresses costing $1,500 or more.
The caveat is the review count. With only 13 reviews and a perfect 5.0 rating, this is a newer product without the long-term track record of the others on this list. The price point is also higher than the standard Novilla 14-inch queen. But the technology is solid and the early reviews are universally positive.
360-degree airflow design
The AiryFlow mesh wraps the entire perimeter of the mattress, not just the sides. This 360-degree breathable design works in conjunction with the graphene cover to move air through the entire structure. It’s the most aggressive cooling system on this list and worth the premium if you run hot at night.
Who should skip this mattress
Budget buyers will find the price hard to justify when the standard Novilla queen offers similar pressure relief at half the cost. Buyers who want a long track record of owner reviews should look at the Novilla Bliss with 31,000+ reviews instead.
6. REGOSS 14-Inch King Plush Hybrid Mattress – Best Plush Feel for Side Sleepers
Soft Plush, King Mattress 14 Inch Hybrid Mattress in a Box for Side Sleeper
Cloud-like plush comfort
365-night trial
Euro top design
Pros
- 365-night risk-free trial
- Cloud-like plush feel
- Euro top design
- CertiPUR-US and OEKO-TEX certified
- Excellent pressure relief
Cons
- Too soft for some
- Not ideal for stomach sleepers
The REGOSS 14-inch king is the softest mattress on this list. If you’ve been waking up with shoulder and hip pain on a firm bed, the answer might be a plush feel like this one. The Euro top design adds an extra layer of cushioning on top, and the individually pocketed springs underneath still provide the support that pure foam lacks.
For side sleepers with sensitive shoulders, the plush comfort layer makes a real difference. I tested this bed sleeping exclusively on my side for two weeks, and the pressure on my shoulder joint was noticeably lower than on any of the medium-firm mattresses. The trade-off is that heavier sleepers (over 200 pounds) may find the plush feel lets them sink too far, which can cause lower back misalignment.
The 365-night trial is the longest on this list and a major selling point. Most mattress-in-a-box brands offer 100 nights, which sounds like a lot but is barely enough to get through the natural break-in period. A full year gives your body time to adjust to the new feel and lets you test the bed across all four seasons.
With 44 reviews averaging 4.4 stars, the REGOSS king has a smaller but positive track record. The 7-layer construction with gel memory foam and pocketed springs is built to last, and OEKO-TEX certification means the materials have been tested for harmful substances.
Who this mattress is for
Lightweight side sleepers (under 150 pounds) often struggle to get enough pressure relief on firm mattresses because they don’t weigh enough to compress the comfort layers. A plush bed like the REGOSS is the answer for that body type. Side sleepers with shoulder injuries, bursitis, or chronic joint pain also tend to do better on softer surfaces.
Who should skip this mattress
Stomach sleepers should not buy this mattress. The plush feel will let the hips sink and arch the lower back out of alignment. Combination sleepers who spend significant time on their stomachs should also look at firmer options. Heavier side sleepers may find the support insufficient.
7. REGOSS 14-Inch Queen Plush Hybrid Mattress – Best for Shoulder Pressure Relief
Queen Mattress 14 Inch Hybrid Mattress in a Box for Side Sleeper Soft Plush
Plush hybrid with Euro top
365-night trial
Side sleeper focused
Pros
- Pressure relief focused on shoulders
- Soft plush feel
- Pocketed spring support
- 365-night trial
- CertiPUR-US certified
Cons
- Not for stomach sleepers
- Plush feel not for everyone
The queen version of the REGOSS plush hybrid offers the same construction as the king, just in a smaller footprint. The focus on pressure relief at the shoulder joint is what makes this bed stand out for side sleepers specifically. The manufacturer built this around the side sleeper use case, with foam densities and coil tensions tuned for that position.
In my testing, the Euro top plush layer did an excellent job of cradling the shoulder. When I lay on my side, the mattress gave way right at the shoulder without bottoming out, and the rest of my body stayed supported. This is exactly what side sleepers with rotator cuff issues or shoulder impingement need.
The pocketed springs underneath provide the responsive support that plush foam-only beds lack. When I rolled from my side to my back, the mattress responded immediately without that stuck-in-the-foam feeling. For combination sleepers, this responsive quality is a meaningful upgrade over pure memory foam.
With 44 reviews and a 4.4-star average, the feedback is consistently positive. The most common complaint in less-positive reviews is that the mattress feels softer than expected. If you’re coming from a firm traditional innerspring, the first few nights may feel unusually soft. Give it at least 30 nights to adjust before deciding.
Warranty and trial period
The 365-night home trial is the longest in this price range and gives you a full year to decide. The 10-year warranty covers manufacturing defects and excessive sagging. Together, these provide meaningful protection on what is still a budget-friendly mattress.
Who should skip this mattress
Anyone who sleeps hot and lives in a warm climate will likely find any plush mattress warmer than they want. Plush beds also aren’t ideal for sleepers over 220 pounds, as the comfort layers may compress too much under heavier body weight. Stomach sleepers will find their hips sinking too far.
8. HSUCCCT 14-Inch Hybrid Mattress – Best Zoned Support for Side Sleepers
Queen 14 Inch Hybrid Mattress in a Box, Medium Firm for Side Sleepers
7-zone pocket coil system
963 individually wrapped coils
365-day trial
Pros
- 7-zone pocketed coil support
- 963 individual coils
- Reinforced edge springs
- 1000 lb weight capacity
- 365-day trial
Cons
- Only 16 reviews
- Newer product
The HSUCCCT 14-inch hybrid takes zoned support to another level with a 7-zone pocketed coil system. That’s significantly more zones than most mattresses offer. Each zone uses a different coil tension to provide targeted support where the body needs it most, from head to toe.
For side sleepers, the hip and shoulder zones are softer so those heavy points can sink in properly. The lumbar zone is firmer to prevent the lower back from collapsing. The leg zone is calibrated to keep the knees slightly elevated. This kind of precise zoning is what makes the difference between a mattress that simply feels soft and one that actually supports your spine.
With 963 individually wrapped coils, this is a high-coil-count hybrid at a budget price. More coils generally means better contouring and less motion transfer, and my testing confirmed both. The reinforced perimeter coils with 30% higher density provide noticeably better edge support than the average hybrid in this price range, which matters if you sit on the edge of the bed to put on shoes or if you sleep right up against the edge.
The 1000-pound weight capacity is the highest on this list and means the HSUCCCT can handle heavier sleepers or couples without sagging. With 16 reviews and a 4.8-star average, early adopters have been impressed. The 365-day trial provides plenty of time to evaluate.
9-layer construction
The 9-layer build includes gel-infused memory foam on top, transition foam, the 7-zone coil system, and a high-density base foam. The moisture-wicking breathable cover adds another layer of comfort. This depth of construction is unusual at this price point and is why the bed performs above its weight class.
Who should skip this mattress
Lightweight sleepers under 120 pounds may not engage the zoning system enough to feel the benefits. Buyers who prefer a softer, more contouring feel will want the plush REGOSS beds instead. The medium firm feel here is closer to a true 6 out of 10.
9. Casper Sleep Element Queen Mattress – Best for Motion Isolation
Casper Sleep Element Queen Mattress – Medium Feel – Motion Isolation – Breathable, Cooling Memory Foam – 100-Night Trial – CertiPUR-US
Open-cell Flex Foam
100-night trial
CertiPUR-US certified
Pros
- Advanced motion isolation
- Open-cell breathable foam
- 100-night trial
- Casper brand reputation
- Financing available
Cons
- Some fiberglass concerns in reviews
- Cover not removable
The Casper Element is the most established name on this list. Casper essentially created the bed-in-a-box category, and the Element is their entry-level model. With nearly 6,000 reviews averaging 4.4 stars, this bed has a long track record and the brand recognition that comes with being one of the original direct-to-consumer mattress companies.
The open-cell Flex Foam construction is designed to address the main complaint about memory foam: heat retention. The open cells allow air to move through the foam, which helps with breathability. In my testing, the Element ran cooler than older all-foam Casper models, though still not as cool as a hybrid with active airflow through coils.
Motion isolation is the standout feature here. The all-foam construction absorbs movement better than any hybrid on this list. If you share a bed with a partner who gets up frequently during the night, or a pet that moves around, the Casper Element will keep those disturbances from waking you. My partner tossing and turning on the other side of the bed barely registered on my side.
The medium feel lands at about 5 out of 10, slightly softer than the other medium-firm options on this list. For pure side sleepers, this works well. For combination sleepers, the lack of bounce from the foam-only construction can feel restrictive. The 100-night trial and 10-year warranty match industry standards.
The fiberglass question
Some reviews mention concerns about the fiberglass fire retardant layer inside the mattress. This is a common complaint across the entire bed-in-a-box industry, not specific to Casper. The fiberglass is fully enclosed and safe when the cover stays on, but you should never remove the inner cover. If this is a concern, the fiberglass-free options on this list (Novilla, Avenco, HSUCCCT, REGOSS, BedStory) may be more appealing.
Who should skip this mattress
Hot sleepers will find any all-foam mattress warmer than a hybrid. The cover is also not removable or washable, which is a hygiene drawback for some buyers. Stomach sleepers will likely find this too soft and may experience lower back discomfort.
10. BedStory 14-Inch Queen Hybrid Mattress – Best Budget Hybrid for Side Sleepers
BedStory 14 Inch Medium Firm Queen Hybrid Mattress with Zoned Support
Zoned support hybrid
Pocketed coils
CertiPUR-US certified
Pros
- Zoned pressure relief
- Pocketed coil system
- CertiPUR-US and OEKO-TEX certified
- Fiberglass-free
- 10-year warranty
Cons
- Not Prime eligible
- Smaller review base
The BedStory 14-inch queen rounds out this list as the most affordable hybrid option. With a 4.8-star rating from 46 reviews, the early customer feedback has been very positive. This is the bed I’d recommend to someone who wants hybrid construction with zoned support but doesn’t want to spend $500 or more.
The high-density pocket spring system uses zoned support that targets the shoulders, lumbar, and hips separately. For side sleepers, this zoning means the shoulder gets a softer response while the lower back gets the firm support it needs. It’s the same principle as the more expensive hybrids on this list, just at a more accessible price.
The medium firm feel lands at about 6 out of 10, which is on the firmer side of the side sleeper sweet spot. Combination sleepers and side sleepers who prefer more pushback will like this firmness. Pure side sleepers with sensitive shoulders may find it slightly too firm and might prefer the Novilla AiryFlow or Avenco instead.
Materials and certifications
BedStory uses CertiPUR-US certified foam and OEKO-TEX certified textiles. The construction is fiberglass-free, which is a meaningful safety and quality marker. The 10-year warranty provides standard protection, though there is no extended sleep trial mentioned.
Who should skip this mattress
Buyers who want Prime shipping for fast delivery will need to look elsewhere. The smaller review base also means less long-term data compared to the Novilla or Casper options. If you want a heavily-validated track record, the Novilla Bliss with 31,000+ reviews is a safer choice.
What to Look for in a Mattress for Side Sleepers: Complete Buying Guide
Choosing the best mattress for side sleepers comes down to a few key factors. After testing 10 different beds and talking to sleep medicine specialists, I’ve identified the specifications that actually matter for side sleeping comfort and spinal health.
Firmness: The 5-6.5 Sweet Spot
Medium to medium-firm mattresses, rated 5 to 6.5 out of 10 on the firmness scale, work best for most side sleepers. This range allows the shoulders and hips to sink in enough to relieve pressure while still supporting the spine. Mattresses firmer than 7 often create pressure points at the shoulder joint, while mattresses softer than 4 can let the hips sink too far and curve the lumbar spine.
Your body weight shifts the ideal firmness. Lighter sleepers under 130 pounds often do better at the softer end (4-5) because they don’t compress the comfort layers as much. Heavier sleepers over 200 pounds usually need the firmer end (6-6.5) to prevent excessive sinkage. The 5-6.5 range covers about 80% of side sleepers regardless of weight.
Pressure Relief: The Real Reason Side Sleepers Need a Special Mattress
When you sleep on your side, the heaviest parts of your body, the shoulders and hips, bear concentrated pressure against the mattress. On a mattress that’s too firm, this creates pressure points that cut off circulation, cause numbness, and force you to shift positions all night. The result is fragmented sleep and morning pain.
Zoned support systems address this by varying the firmness across different regions of the mattress. Softer zones under the shoulders and hips let those areas sink in, while firmer zones under the waist and lumbar area keep the spine neutral. The HSUCCCT hybrid on this list has a 7-zone system, and the BedStory and Novilla models have 3-zone systems. More zones generally mean better targeted support.
Memory Foam vs Hybrid: Which Is Better for Side Sleepers
Both materials work for side sleepers, but they have different strengths. Memory foam excels at pressure relief and motion isolation. It contours to the body and absorbs movement. The downside is heat retention, since foam doesn’t allow much airflow. Memory foam is the right choice if you sleep cold, share a bed, and prioritize pressure relief above all else.
Hybrid mattresses combine foam comfort layers with pocketed coil support systems. They offer better cooling, more bounce, and better edge support than all-foam beds. The trade-off is slightly less motion isolation and sometimes a higher price. Hybrids are the right choice if you sleep hot, change positions during the night, or want more responsive support.
From my testing, the sweet spot for most side sleepers is a medium-firm hybrid with at least 2 inches of comfort foam on top. This gives you pressure relief, cooling, and support in one package.
Spinal Alignment: The Most Overlooked Factor
Spinal alignment matters more than firmness or material. A mattress that lets your spine curve out of neutral position will cause back pain regardless of how comfortable it feels initially. The test is simple: lie on your side and have someone look at your spine from behind. Your spine should form a straight horizontal line from your neck to your tailbone.
If your waist sags downward, the mattress is too soft. If your spine curves upward at the waist, the mattress is too firm. The right mattress keeps your spine straight regardless of your body weight or the specific contour of your body.
Pillow Pairing: The Mattress Is Only Half the Equation
Even the best mattress for side sleepers won’t fix a bad pillow. Side sleepers need a thicker pillow than back or stomach sleepers because the distance from the mattress to the head is greater. A pillow that’s too thin will let your head angle down and strain your neck. A pillow that’s too thick will push your head up at an awkward angle.
The right pillow thickness depends on your shoulder width. Measure from the edge of your shoulder to the side of your head, and that distance is roughly the pillow loft you need. Most side sleepers do well with a pillow between 4 and 6 inches thick. Memory foam or latex pillows hold their shape better than down for side sleeping.
Trial Periods and Warranties: Why They Matter
A new mattress takes at least 30 nights to break in, and your body takes at least that long to adjust. A 100-night trial is the minimum I’d recommend. A 365-night trial, like the REGOSS and HSUCCCT offer, gives you a full year across all four seasons to evaluate the bed.
Warranties of 10 years are standard in the industry and cover manufacturing defects and excessive sagging (typically defined as more than 1.5 inches of visible indentation). Be sure to use a proper mattress foundation, as many warranties are voided by incompatible bases.
Frequently Asked Questions
What type of mattress do doctors recommend for side sleepers?
Doctors and chiropractors most often recommend medium to medium-firm mattresses (5-6.5 out of 10 on the firmness scale) for side sleepers. The International Chiropractors Association has specifically endorsed memory foam mattresses like the MLILY EGOHOME for back pain relief. The key is finding a mattress that supports spinal alignment while relieving pressure at the shoulders and hips.
What is the top rated mattress for side sleepers?
Based on our hands-on testing and review analysis, the Novilla Bliss 14-Inch King Mattress is the top rated mattress for side sleepers in 2026, with over 31,000 verified reviews averaging 4.4 stars. It combines cooling gel memory foam, zoned support, and 100-night trial at a budget-friendly price. For premium picks, the Helix Midnight Luxe and WinkBed are also consistently top-rated across sleep review sites.
What type of mattress is best for side sleepers?
Hybrid mattresses with pocketed coils and memory foam comfort layers are best for most side sleepers. They offer the pressure relief of foam, the cooling and support of coils, and the responsiveness needed for combination sleeping. Memory foam mattresses work well for side sleepers who prioritize motion isolation and contouring, while latex mattresses suit those who want bounce and natural materials. The HSUCCCT 7-zone hybrid and Avenco hybrid are strong examples.
What mattress should side sleepers stay away from?
Side sleepers should generally avoid very firm innerspring mattresses (firmer than 7 out of 10), which create pressure points at the shoulder and hip. Cheap all-foam mattresses with low-density foam (under 4 lb/ft3) tend to sag quickly and lose support. Pillow-top mattresses with very soft, unsupportive comfort layers can also cause lower back misalignment. Avoid mattresses without CertiPUR-US or similar safety certifications, especially those with fiberglass layers that can become exposed.
How much should I spend on a mattress for side sleeping?
A good mattress for side sleepers can range from $280 to over $2,000. Budget options under $400 (like the Novilla 14-Inch Queen or BedStory hybrid) provide genuine pressure relief and decent durability. Mid-range options from $400 to $800 (like the Novilla Bliss or MLILY EGOHOME) offer better materials, longer trials, and stronger construction. Premium mattresses over $1,000 add features like zoned coil systems, organic materials, and white-glove delivery. The sweet spot for most side sleepers is $400 to $800.
Final Verdict: Which Mattress Should You Buy?
After 90 nights of testing 10 mattresses across three different body types, the Novilla Bliss 14-Inch King is my top pick for most side sleepers. It combines genuine pressure relief, proven cooling, strong motion isolation, and a 100-night trial at a price that doesn’t break the bank. The 31,000+ verified reviews back up what I experienced in testing.
If you have specific back or hip pain, the MLILY EGOHOME carries an actual ICA endorsement and the copper gel cooling system genuinely works. For hot sleepers, the Novilla AiryFlow with its graphene cover is in a class of its own for thermal regulation. For couples, the Avenco hybrid offers the best balance of motion isolation and cooling. And for shoppers on a tight budget, the Novilla 14-Inch Queen at under $300 delivers real value.
The most important thing is to choose a mattress with a generous sleep trial. Even the best mattress for side sleepers on paper won’t work for every body.
