Quick answer: the best mattress for most side sleepers is a medium to medium-firm hybrid, roughly 5 to 7 out of 10, with a contouring comfort layer over supportive coils. Our top pick is the Helix Midnight Luxe, a medium-feel hybrid its maker markets for side sleepers. Too firm and the shoulder and hip have nowhere to sink; too soft and the hips drop below the shoulders, so the right choice also depends on your weight and how you sleep.

Who This Is For
- You sleep mainly on your side and wake up with sore shoulders or hips
- Your current mattress feels fine lying down but uncomfortable after a few hours
- You wake up and shift position frequently to relieve pressure
- You’re shopping for a new mattress and aren’t sure what firmness to choose
- This isn’t a fit if your pain began after an injury, is sudden or severe, or has not improved in a couple of weeks. That needs a doctor, not a new bed (see the section on when to see a doctor below).
Why Side Sleepers Need Something Different
Side sleeping concentrates your body weight onto two relatively small areas, the shoulder and the hip, instead of spreading it across your back. A mattress that’s too firm won’t give at those points, which creates pressure and can leave your spine tilted rather than straight. A mattress that’s too soft lets the hips sink lower than the shoulders, which pulls the lower back out of alignment the other way.
Firmness advice that is specific to side sleepers mostly comes from mattress testing rather than medical research. In Sleep Foundation’s lab reviews, the WinkBed Luxury Firm (6 out of 10) scored best for side sleepers weighing 130 to 230 pounds, the Brooklyn Bedding Signature Hybrid in Medium Firm (6) was singled out for the same weight range, and the Leesa Sapira Chill review says its medium and medium-firm versions suit side sleepers under 230 pounds while the firm version suits heavier ones. In other words, lighter side sleepers tend to do well a notch softer and heavier ones a notch firmer.
The general medical guidance is less specific. Cleveland Clinic says a medium-firm mattress can help with chronic back pain and suggests starting on the firmer side so you can adjust, since you can always add softness with a topper. It does not give side-sleeper-specific firmness advice. A small study of 27 adults with chronic low back pain (most of them side sleepers) found less back and shoulder pain after 12 weeks on prescribed medium-firm mattresses, though a study that small, without a comparison group, is suggestive rather than proof.

How We Chose
How we picked these: each pick is compared on manufacturer specifications, independent lab and tester reviews, and patterns across verified buyer reviews, then rated on a 10-point scale for how well it fits the specific need named in its heading, not just general quality.
We don’t accept payment for placement in this list, and picks are updated if a better option emerges or a listing goes stale. Specs, trial terms and prices were last checked on 4 October 2026 against manufacturer pages and Amazon listings. Where a current price or trial term is not quoted, check the maker’s page or the listing before buying.
What to Look For
Medium to medium-firm feel (not firm)
A mattress marketed as “firm” or “extra firm” rarely works well for side sleeping because there’s little give at the shoulder and hip. Look for a stated firmness of about 5 to 7 out of 10, and go toward the softer end if you are lighter and the firmer end if you are heavier.
Zoned or contouring support
Some mattresses use softer foam or different coil support under the shoulders and hips, with firmer support under the waist and lower back to prevent sagging. Not every mattress that says medium-firm does this, so check whether the maker or an independent tester describes zoning.
Enough contouring material on top
A foam or pillow-top comfort layer over coils lets the shoulder sink in while the coils hold the midsection up. For the full trade-off between foam and coils, see our comparison of memory foam vs. hybrid mattresses.
Cooling, if you run hot
Sleep Foundation notes that materials such as memory foam can trap heat, which may bother hot sleepers. If overheating already disrupts your sleep, prioritize a hybrid with a cooling cover or better airflow over a dense all-foam design. See our guide to the best mattresses for hot sleepers if cooling is your main priority.
Best Mattresses for Side Sleepers
Prices and promotions change often, so use the links and the brand’s site to check the current price before buying.
Helix Midnight Luxe: Best Overall
Rating: 9.2/10
What it is: A 13.5-inch hybrid that Helix describes as a medium feel, great for side sleepers, with zoned lumbar support and a GlacioTex cooling cover. In independent testing, Mattress Clarity measured it at about 6 out of 10 firmness and describes a pillow top, gel memory foam and more than 1,000 pocketed coils.
Pros: Adaptive foam cushions pressure points well; the coil core stops the midsection from sinking too far, which keeps the spine more level than an all-foam bed; Mattress Clarity’s testing rates it highly for side sleepers.
Cons: Premium price point, and prices and trial terms change, so check both on Helix’s page before buying; one Mattress Clarity tester still noted some pressure at the shoulders and hips; hybrids run heavier and are harder to move than all-foam mattresses.
Best for: Side sleepers who want the closest thing to a “safe default” pick.
Why we recommend it: The combination of pressure-relieving foam, coil support and a medium feel that matches the firmness range testers favor for side sleepers is why this is the safest default recommendation for most side sleepers.
Keetsa Pillow Plus: Best Medium-Firm Hybrid
Rating: 8.7/10
Check current pricing at Keetsa
What it is: A medium-firm hybrid with a soft, moisture-wicking cover, body-contouring memory foam, a double layer of comfort foam and individually wrapped coils. Keetsa sells it direct with a 90-night in-home trial and a 12-year warranty, and its own site showed a 4.8 out of 5 average from more than 1,100 reviews on 4 October 2026. Sale pricing changes, so check the current queen price before you buy.
Pros: A medium-firm feel in the range this guide recommends for side sleepers; memory foam over pocketed coils combines contouring with support; a 90-night trial and a 12-year warranty.
Cons: Some reviewers on Keetsa’s site found it firmer than they expected, so lighter side sleepers should be cautious; it is sold direct, so there is no store to test it in beyond the home trial; reviews on the maker’s own site are not independent lab testing.
Best for: Side sleepers who want a medium-firm hybrid from a direct brand with a real trial period.
Why we recommend it: It pairs a medium-firm feel with contouring foam over coils and a 90-night trial, which makes it a lower-risk way to test a medium-firm bed than a mattress with a short return window.
Casper Original Hybrid: Best for Zoned Support
Rating: 8.6/10
What it is: An 11-inch hybrid that Casper describes as a medium feel with zoned support, meaning firmer foam under the hips, waist and lower back, with breathable open-cell foam over encased coils and a 100-night trial. The Amazon listing averaged 4.3 out of 5 from about 1,300 ratings on 4 October 2026.
Pros: Zoned support targets the hips and lower back, where side sleepers tend to sink; open-cell foam is meant to sleep cooler than dense memory foam; a well-known brand with a large number of Amazon ratings.
Cons: At 11 inches it is thinner than the luxury hybrids here; size and price vary by listing, so confirm the queen option and the current price on Amazon; Casper’s own description is not independent testing.
Best for: Side sleepers who want zoned support from a widely reviewed hybrid.
Why we recommend it: Zoned support under the hips and lower back, a medium feel and a large pool of buyer ratings make it a practical middle option between the premium hybrids and all-foam beds.
Nectar Premier: Best Memory Foam Option
Rating: 8.4/10
What it is: A 13-inch memory foam mattress in a medium-firm feel with a 1-year trial, which its Amazon listing says adds an extra inch of contouring foam and a cooler cover compared with Nectar’s Classic model. The queen listing averaged 4.1 out of 5 from about 310 ratings on 4 October 2026.
Pros: Deep contouring foam for pressure relief at the shoulder and hip; a medium-firm feel; a cooler cover over the foam; a trial period long enough to test it properly.
Cons: All-foam beds can sleep warmer than coil hybrids, which matters if you run hot; fewer ratings than the Casper listing; confirm size, price and trial terms on the listing before you order.
Best for: Side sleepers who prefer deep foam contouring to a bouncier coil feel.
Why we recommend it: Medium-firm contouring foam is a straightforward fit for the shoulder and hip, which is why it earns the all-foam pick.
Aviya Mattress: Best Premium Hybrid
Rating: 8.9/10
Check current pricing at Aviya Mattress
What it is: A hybrid mattress with individually wrapped coils under high-density foam and a cooling comfort layer, with CertiPUR-US certified foams. Aviya now lists three firmness levels: Plush (3.5 out of 10), Luxury Firm (5.5, its best seller) and Firm (8.5). Aviya’s site showed prices starting at $649 on 4 October 2026, during a sale, so expect the regular price to be higher. It comes with a 100-night in-home trial and a 10-year warranty.
Pros: Real innerspring bounce avoids the “stuck in a hole” feeling of all-foam beds while still cushioning pressure points; the Luxury Firm level lands in the recommended range; a 100-night trial and 10-year warranty.
Cons: Aviya sells direct, so there is no store to test it in, only the at-home trial; there is less independent lab testing of it than of the other picks here.
Best for: Side sleepers who want genuine coil support under a contouring comfort layer, with a choice of firmness and a real trial period.
Why we recommend it: The combination of coil support, a cooling comfort layer and a mid-range price that starts well below the luxury picks makes it a strong direct-to-consumer alternative to the other picks above.
How to Choose Based on Your Situation
- Want a reliable default: Helix Midnight Luxe
- Want a medium-firm hybrid with a long home trial: Keetsa Pillow Plus
- Want zoned support from a widely reviewed brand: Casper Original Hybrid
- Prefer deep foam contouring: Nectar Premier
- Want direct-from-brand with a real trial period: Aviya Mattress
Common Buying Mistakes
- Buying “firm” or “extra firm” out of habit. A lot of people default to a firmer mattress thinking it means better support, but for side sleeping it usually just means unrelieved pressure at the shoulder and hip.
- Judging only by the firmness number. Two mattresses can both say “medium-firm” and feel completely different depending on the comfort layers and whether the support is zoned.
- Choosing all-foam without considering heat. If you already run hot at night, a dense all-foam mattress without cooling features can make that worse, even if the pressure relief is good.
- Assuming softer is always better for side sleeping. Too little support lets the hips sink lower than the shoulders, which pulls the spine out of alignment in the other direction.
- Ignoring trial terms. Several brands require a minimum number of nights before a return and some charge a return fee, so read the terms before you order.
When to See a Doctor Instead
A new mattress is a reasonable fix for ordinary aches that follow how you sleep. It is not the right fix for every shoulder or hip pain. The NHS advises seeing a GP if shoulder pain is getting worse or has not improved after 2 weeks, or if it is very difficult to move your arm or shoulder. It advises urgent help for sudden or very bad pain, pain that started after an injury such as a fall, being unable to move the arm, pins and needles that do not go away, severe pain in both shoulders, or feeling feverish or unwell (NHS 111 Wales: shoulder pain). If your pain follows that kind of pattern, see a doctor before spending money on a mattress.
Frequently Asked Questions
What is the best mattress for side sleepers in 2026?
For most side sleepers, a medium to medium-firm hybrid is the best starting point, and our top pick is the Helix Midnight Luxe. If you are unsure about firmness, a brand that sells several firmness levels, such as Aviya, lets you choose the one that matches your weight.
What firmness is best for side sleepers?
Medium to medium-firm, roughly 5 to 7 out of 10. Independent testers tend to favor about 6 out of 10 for side sleepers between 130 and 230 pounds, a bit softer for lighter sleepers and a bit firmer for heavier ones.
Is memory foam or hybrid better for side sleeping?
Both can work well. Memory foam gives deep pressure relief but can trap heat; hybrids combine foam contouring with coil support and are generally more responsive and better ventilated.
How do I know if my mattress is causing my shoulder or hip pain?
If the pain is worse in the morning and eases as you move around during the day, that pattern points to your sleep setup rather than a separate injury. See a doctor if the pain is getting worse or has not improved after 2 weeks, started after an injury, or comes on suddenly and severely.
How often should I replace my mattress?
Cleveland Clinic says it’s best to change a mattress about every 10 years, especially if you’ve had physical changes such as an injury or a significant weight gain or loss.
What This Mattress Cannot Fix
A better mattress addresses pressure and alignment while you sleep, not every source of shoulder or hip pain. If your pain doesn’t ease as you move around during the day, or shows up regardless of how you slept, that points away from your mattress and toward something worth a doctor’s opinion, as covered above. A mattress also can’t fix poor sleep posture on its own: if you sleep with your top arm tucked under a pillow or your knees unsupported, no amount of zoned foam will fully compensate. Pairing the right mattress with a pillow suited to side sleepers with shoulder pain and, where useful, a pillow between the knees gets closer to solving the whole problem than the mattress alone.
Key Takeaways
Side sleepers do best on a medium to medium-firm mattress, about 5 to 7 out of 10, with real contouring at the shoulders and hips, not the firmest option on the shelf. Hybrids are the safest general pick; which specific one is worth it depends mostly on budget, your weight and whether you want to choose your own firmness level. Pain that is sudden, severe, worsening or follows an injury needs a doctor, not a mattress.
