Best Mattress for Side Sleepers
Side sleeping puts your whole body weight on your shoulder and your hip. Here is how to pick a mattress that handles it.
The best mattress for side sleepers is a medium soft to medium hybrid or memory foam bed, roughly 4 to 6 on a 10 point firmness scale. You need three to four inches of comfort layer so your shoulder and hip can settle in, and a support core underneath that keeps the gap at your waist filled. Lighter sleepers should go softer, heavier sleepers firmer. If you wake with a sore shoulder, your mattress is almost certainly too firm.
Side sleeping is the most common sleep position. Somewhere around six in ten adults sleep on their side, and it is the position most likely to leave you with a sore shoulder or an aching hip if the mattress is wrong.
The reason is simple geometry. On your back, your weight spreads across your whole body. On your side, it lands on two narrow points, your shoulder and your hip, and everything in between has to be supported or your spine curves.

“Sleep surface is one of the few modifiable factors in chronic musculoskeletal pain that patients control directly. When a mattress fails to support neutral spinal alignment, paraspinal muscles compensate through the night, and patients present with morning stiffness that eases within an hour of getting up. That pattern is worth taking seriously.”

Why Do Side Sleepers Need Pressure Relief?
When you sleep on your side, your body weight lands on two contact points. Your shoulder takes the load from your upper body, your hip takes the load from your lower body, and the gap at your waist has nothing under it unless the mattress fills it.
If the surface is too firm, your shoulder and hip cannot sink in. Blood flow at those points gets restricted, you get numbness or a dull ache, and you roll over repeatedly through the night without waking up properly. If it is too soft, your hip drops too far and your spine bends the other way.
The sweet spot is a mattress that lets your shoulder and hip settle in while still filling the gap at your waist. That is a support core and comfort layer working together, not a firmness number.
What Firmness Is Best for Side Sleepers?
Side sleepers should choose a firmness of 4 to 6 on a 10 point scale, medium soft to medium. That range gives your shoulder and hip somewhere to go while keeping your spine level.
Firmness Recommendations by Body Weight
| Body weight | Firmness range | Why |
|---|---|---|
| Under 130 lbs | Soft to medium soft, 3 to 5 | Less weight means less sink. A medium firm will feel firm and leave your shoulder unsupported |
| 130 to 230 lbs | Medium soft to medium, 4 to 6 | The standard range. Most side sleepers land here |
| Over 230 lbs | Medium to medium firm, 5 to 7 | More weight means more sink. A soft mattress will let your hip drop too far |
Body weight ranges are a starting point, not a rule. Shoulder width and hip width change the answer too.
This is why in store testing matters more for side sleepers than any other position. Two people the same weight with different shoulder widths need different beds, and no online quiz can measure that.
Best Memory Foam and Hybrid Mattresses for Side Sleepers
Memory Foam
Memory foam contours around your shoulder and hip more completely than any other material, which makes it the best choice if pressure is your main complaint. The tradeoff is that it can feel slow to move on and it holds heat more than a hybrid.
Hybrid
Foam or latex over a pocketed coil core. You get relief at your contact points plus a support base that keeps your waist from dipping. For most side sleepers this is where we start.
Latex
Latex is responsive rather than sinking, so it holds your spine level and is easy to move on. It runs firm, so side sleepers usually want a latex hybrid with a softer top rather than an all latex build.
The Right Pillow
Side sleepers need more pillow loft than back or stomach sleepers, because there is more distance between your ear and the mattress. The wrong pillow will undo a correctly chosen mattress. Bring your current pillow when you shop, or test ours while you are lying down.
Memory Foam vs. Hybrid: Which Is Better for Side Sleepers?
| Memory foam | Hybrid | |
|---|---|---|
| Pressure relief | Excellent | Very good |
| Support at your waist | Good | Excellent |
| Cooling | Fair to good | Very good |
| Ease of moving | Fair | Very good |
| Best for | Shoulder pain, lighter sleepers | Most side sleepers, heavier sleepers |
Bottom line: choose memory foam if pressure relief is your top priority. Choose a hybrid if you want relief plus support, you sleep warm, or you change position through the night.

BedMATCH measures how your body actually distributes weight on its side, then narrows the floor to what fits.
Best Mattress for Side Sleepers with Shoulder Pain
Shoulder pain from side sleeping almost always means the mattress is too firm. Your shoulder is the narrowest, heaviest contact point on your body when you are on your side, and if it cannot sink in, all of your upper body weight sits on it for hours.
The fix is more comfort layer, not a different pillow. Look for three to four inches of memory foam or a soft latex top over a supportive core. Test by lying on your side for ten minutes and paying attention to whether your shoulder feels compressed or supported.
Best Mattress for Side Sleepers with Hip Pain
Hip pain is the mirror image. It can come from a mattress that is too firm, where your hip carries too much concentrated weight, or from one that is too soft, where your hip sinks and your lower back twists.
If your hip aches in the same spot every morning, the mattress is likely too firm. If the ache is more in your lower back and tailbone area, it is likely too soft. That distinction is the fastest way to narrow your options.

Helix
Helix builds different models for different sleep positions rather than one bed for everyone, and side sleeping is the position their lineup is most clearly designed around. The Midnight models pair a memory foam comfort layer with a wrapped coil core.
The Luxe tier adds a zoned coil layer and a thicker quilted top, which gives your shoulder more room to settle without letting your waist drop.
A Wesper sleep tracking study of Helix owners reported 87 to 94 percent of participants saw improved sleep quality after switching.
Tempur-Pedic
TEMPUR material responds to your body heat and weight, so it contours around your shoulder more completely than standard memory foam. If you wake with a compressed, aching shoulder, this is the material that solves it.
The Adapt and ProAdapt lines run soft through firm. Side sleepers usually land on Adapt Medium or ProAdapt Soft. If you run warm, the Breeze models add cooling that Tempur-Pedic measures at up to 10 degrees cooler.
Purple
The GelFlex Grid buckles under concentrated weight and stays firm everywhere else, which is close to a perfect description of what a side sleeper needs. Your shoulder and hip sink in, your waist stays held up.
Because it is an open grid rather than solid foam, air moves through it. Side sleepers who sleep hot often end up here.
Purple cites SleepScore Labs research reporting 63 to 68 percent pain reduction among study participants and 2 to 4 times better heat dissipation.
Beautyrest
Beautyrest invented the pocketed coil in 1925, and the World Class and Black lines are the most developed version of it. Coils are zoned so support varies along the length of the mattress.
For side sleepers the appeal is a plush surface that still holds your waist. If memory foam feels like too much and latex feels like too little, this is the middle ground.
Avocado
GOLS certified organic latex over pocketed coils, with organic cotton and wool in the cover, and five organic and safety certifications including GOTS and GREENGUARD Gold.
Be aware that Avocado Green sleeps firmer than most side sleepers expect. Latex pushes back rather than sinking in, which is great for alignment and less forgiving at your shoulder.
Avocado holds an endorsement from the American Chiropractic Association.
What to Test for in Store as a Side Sleeper
- Lie on your side, not your back. Sounds obvious. Most people still test on their back.
- Check your waist. Have someone look at whether there is a visible gap between your waist and the mattress. There should not be.
- Give your shoulder ten minutes. Pressure builds slowly. Thirty seconds tells you nothing.
- Use a pillow with the right loft. Testing with a flat display pillow will make every mattress feel wrong.
- Roll over. If getting from your side to your back takes effort, you will do it twenty times a night.
Common Mistakes I See on the Sales Floor
Choosing a mattress that is too firm
This is the number one mistake, and it usually comes from someone being told firm is better for your back. For a side sleeper a too firm mattress means your shoulder and hip carry all your weight on two small points. That is where the numbness and the morning ache come from.
Ignoring body weight in the firmness decision
A 120 pound side sleeper and a 240 pound side sleeper need different beds even if they sleep identically. The lighter sleeper barely compresses the comfort layer, so a medium feels firm to them. The heavier sleeper goes straight through it. I ask about weight every time, and it is not a rude question, it is the most useful variable I have.
Not testing long enough in store
Shoulder pressure builds over minutes, not seconds. I tell people to lie on their side, close their eyes, and stay there long enough to get slightly bored. That is roughly when the mattress starts telling you the truth.
Forgetting about the pillow
You can pick the right mattress and still wake up with neck pain because your pillow is two inches too flat. Side sleepers need more loft than they think. Test the pillow and the mattress together, because they are one system.
Assuming a plush top means a soft bed
A pillow top over a very firm core will feel soft for the first thirty seconds and firm for the next eight hours. What matters is how far your shoulder actually travels, not how the surface feels to your hand.

Why In-Store Testing Matters
Side sleeping is the position where fit varies most between people. Shoulder width, hip width, and body weight all change how far you sink and where the pressure lands. Two people who describe their sleep the same way can need completely different mattresses.
That is not something a product page can solve. It is something you find out in about fifteen minutes lying down.
Every Sit 'n Sleep store offers BedMATCH, a diagnostic fitting that takes about three minutes. You lie down on a calibrated bed while it takes more than one thousand measurements of your body, then narrows the floor to the comfort range that actually fits you. It is free and you do not need an appointment.
We have 37+ stores across Southern California, in Los Angeles, Orange County, the Inland Empire, and Ventura County. Find the store closest to you, and take your time. Every mattress is backed by our 120-night comfort trial.

Frequently Asked Questions
Side sleepers do best with a firmness of 4 to 6 on a 10 point scale, medium soft to medium. That range lets your shoulder and hip settle in while still supporting the gap at your waist. Adjust for body weight: under 130 pounds go softer, 3 to 5, and over 230 pounds go firmer, 5 to 7.
Both work well. Memory foam gives you the most pressure relief at your shoulder and hip, which makes it the better choice if shoulder pain is your main complaint. A hybrid gives you relief plus stronger support at your waist, sleeps cooler, and is easier to move on. Most side sleepers do well on a hybrid, and heavier side sleepers usually should start there.
Shoulder pain from side sleeping usually means your mattress is too firm. Your shoulder is the narrowest and heaviest contact point when you are on your side, and if it cannot sink into the comfort layer, your whole upper body weight sits on it for hours. The fix is more comfort layer, generally three to four inches of memory foam or a soft latex top over a supportive core.
Yes. Side sleepers need a thicker, higher loft pillow than back or stomach sleepers, because there is more distance between your ear and the mattress when you are on your side. A pillow that is too flat will leave your neck bent all night and can undo an otherwise correct mattress choice. Test your pillow and mattress together, since they work as one system.
Yes, a firm mattress is typically not recommended for side sleepers. Without enough give at the surface, your shoulder and hip carry concentrated weight all night, which restricts blood flow and causes the numbness and aching that sends people back to the store. There are exceptions for heavier sleepers, who need more support underneath, but even then the comfort layer should be generous.
It depends on which direction the mattress is wrong. If your hip aches in the same spot every morning, the mattress is likely too firm and you need more comfort layer. If the ache is more in your lower back and tailbone area, the mattress is likely too soft and your hip is sinking too far. A medium hybrid with zoned support handles both failure modes better than most alternatives.
