Mattresses for Side Sleepers

Why Side Sleepers Need a Different Kind of Mattress

Side sleeping is the most common sleep position, used by an estimated 60% of adults. While it offers benefits like reduced snoring and improved digestion, it also creates unique challenges for your mattress. When you sleep on your side, your full body weight concentrates on a smaller surface area — primarily your shoulder and hip — creating intense pressure points that demand a specific type of support. The best mattress for side sleepers cushions these pressure points while keeping your spine aligned from head to tailbone.

At LA Mattress Stores, we have curated a collection of mattresses specifically chosen for side sleepers. Our selection includes options from Tempur-Pedic, Stearns & Foster, Helix, and Diamond Mattress — each tested and selected for their ability to deliver the pressure relief and support that side sleeping demands.

What Side Sleepers Need in a Mattress

Understanding the biomechanics of side sleeping helps explain why not every mattress works for this position:

• Shoulder Pressure Relief: Your shoulder is the widest point bearing weight in the side position. A mattress that is too firm creates painful pressure here, leading to shoulder pain, numbness, and frequent position changes that disrupt deep sleep. The mattress must allow your shoulder to sink in enough to prevent this buildup.
• Hip Cushioning: Your hip is the heaviest point of contact with the mattress when side sleeping. If the mattress cannot cushion the hip, it creates misalignment with the lower spine and can trigger or worsen lower back pain. Adequate contouring at the hip is essential for a side sleeper mattress.
• Spinal Alignment: For side sleepers, proper spinal alignment means your spine forms a straight horizontal line when viewed from behind. If the mattress is too soft, your hips sink below your shoulders. If too firm, your hips stay elevated above your shoulders. Either scenario creates spinal misalignment and muscle strain.
• Conforming Comfort Layers: Side sleepers benefit most from mattresses with thick, body-conforming comfort layers — memory foam, TEMPUR material, or high-density polyfoam. These materials fill the gap between your body's curves and the mattress surface, distributing weight more evenly and reducing point pressure.

How to Choose the Best Mattress for Side Sleepers

If you are searching for a mattress for side sleepers near me in Los Angeles, here are the key factors to prioritize:

• Firmness Level: Most side sleepers do best with a medium to medium soft mattress (4–6 on the firmness scale). Lighter side sleepers (under 130 lbs) may prefer medium soft for adequate pressure relief. Average-weight side sleepers (130–230 lbs) typically find medium ideal. Heavier side sleepers (over 230 lbs) may prefer medium firm, as their body weight naturally compresses the comfort layers more.
• Comfort Layer Thickness: Look for at least 3 inches of comfort foam above the support layer. Thinner comfort layers do not provide enough cushioning for shoulder and hip pressure relief. Premium side sleeper mattresses like the Tempur-Pedic LuxeAdapt feature 4+ inches of contouring material.
• Memory Foam vs. Hybrid: All-foam mattresses (especially memory foam and TEMPUR material) generally provide the best pressure relief for side sleepers due to their deep contouring properties. hybrid mattresses with thick foam tops can also work well, offering pressure relief with added airflow and bounce. The Helix Midnight was specifically designed for side sleepers in a hybrid format.
• Motion Isolation: Side sleepers tend to change positions more frequently than back sleepers. If you share a bed, strong motion isolation prevents your movements from disturbing your partner. Memory foam and TEMPUR material excel here.
• Pillow Compatibility: Side sleepers need a thicker pillow to fill the gap between their head and the mattress surface. A mattress with good shoulder contouring reduces this gap, allowing a more comfortable pillow height. Our sleep consultants can recommend pillow pairings with your chosen mattress.

Side Sleeper Mattress Comparisons

Memory Foam vs. Hybrid for Side Sleepers

All-foam memory foam mattresses deliver the deepest contouring and best pressure relief for side sleepers. They excel at absorbing your shoulder and hip, creating a cradling sensation that distributes weight evenly. The trade-off is less airflow and minimal bounce. Hybrid mattresses offer a balance — foam comfort layers contour to your body while coil support provides airflow, edge support, and responsiveness. For side sleepers who sleep hot or want more bounce, a hybrid like the Helix Midnight Luxe is an excellent choice. For maximum pressure relief, a memory foam mattress like the Tempur-Pedic TEMPUR-ProAdapt Soft is hard to beat.

Soft vs. Medium for Side Sleepers

A soft mattress (3–4 on the scale) provides maximum cushioning but may not offer enough support for heavier side sleepers, potentially allowing the hips to sink too deep. A medium mattress (5–6 on the scale) balances pressure relief with support and works for the widest range of body types. Our general recommendation: start with medium and only go softer if you are under 150 lbs or specifically need more cushioning.

Side Sleeper Mattress FAQ

Is a firm mattress bad for side sleepers?

Generally, yes. A firm mattress does not allow sufficient sinkage at the shoulder and hip, creating concentrated pressure points and spinal misalignment for side sleepers. This can lead to shoulder pain, hip pain, numbness in the arms, and restless sleep. Side sleepers should avoid anything above a 7 on the firmness scale. If you need more support due to higher body weight, choose a medium firm rather than firm — the comfort layers will still compress under your weight while providing better pressure relief than a true firm surface.

What causes shoulder pain when sleeping on your side?

Shoulder pain from side sleeping is almost always caused by excessive pressure. When the mattress is too firm to allow your shoulder to sink in, your body weight concentrates on a small area, compressing blood vessels and creating pain. A mattress with adequate contouring — like memory foam or a thick pillow top — distributes this pressure across a larger surface area. Additionally, using a supportive pillow at the right height prevents your head from tilting and creating neck and shoulder strain.

Can side sleepers use an adjustable base?

Yes. While adjustable bases are often associated with back sleeping positions, side sleepers can benefit from slight head elevation (which can reduce snoring and acid reflux) and slight foot elevation (which can improve circulation). The key is choosing a mattress that flexes well — memory foam and hybrid mattresses are ideal for adjustable bases. Explore our adjustable bed collection for compatible options.

Should couples who are both side sleepers choose a specific mattress?

If both partners are side sleepers, prioritize pressure relief and motion isolation. Memory foam mattresses like Tempur-Pedic excel in both areas, preventing either partner's movements from disturbing the other while cushioning both sleepers' shoulders and hips. A queen or king size gives each side sleeper room to find their comfortable position. Our mattresses for couples collection features additional options selected for shared sleep compatibility.
