Best Mattress for Side Sleepers: 6 Top Picks for 2026

About 74% of people sleep on their side at least part of the night, according to the Sleep Foundation. But side sleeping concentrates your body weight on two narrow points: your shoulder and your hip. That's why mattress choice matters more for side sleepers than any other sleep position.

Pressure relief is priority #1. Your mattress needs a soft-enough comfort layer to let your shoulder and hip sink in. If they can't sink, you get pressure buildup that causes numbness, tingling, and morning pain. Memory foam excels here because it conforms precisely to your body shape.

Spinal alignment is priority #2. While the top layer cradles your pressure points, the support layer underneath needs to keep your spine in a straight horizontal line. If your hips sink too far, your lower back curves and you wake up with back pain. A good mattress balances both.

Temperature regulation matters. Side sleepers tend to sleep hotter because more of their body surface is in contact with the mattress. Look for gel-infused foam, open-cell structures, or hybrid designs with coils that promote airflow.

If your current mattress is too firm for side sleeping but otherwise in good shape, a topper is a cost-effective fix. Here's what to look for:

• Thickness: 2-3 inches. Any thinner and it won't make enough difference; any thicker and it can make your bed feel unstable.
• Material: Memory foam (4-5 lb density) for maximum pressure relief, or latex for a cooler, more responsive feel.
• Firmness: Medium-soft to medium. You want the topper to add cushion, not more firmness.

Our pick: A 3-inch gel-infused memory foam topper in the $60-$100 range hits the sweet spot. Brands like Lucid, Sleep Innovations, and Linenspa all make solid options available on Amazon. Look for one with a removable, washable cover.

If you're waking up with shoulder or hip pain, your mattress is almost certainly the problem — not your sleep position. Side sleeping is actually one of the healthiest positions (it improves circulation, reduces snoring, and helps with acid reflux). The key is having the right surface.

For shoulder pain: Focus on mattresses with a softer shoulder zone. The Casper Original has zoned support that's specifically softer at the shoulders. Alternatively, a thick memory foam comfort layer (3"+) will naturally conform to your shoulder shape.

For hip pain: Your hips need a balance of cushion and support. Too soft and your hips sink too far, curving your spine. Too firm and the pressure builds up. A hybrid mattress like the Helix Midnight provides the best balance — memory foam on top for cushion, pocketed coils below for support.

Pro tip: Pairing your mattress with an adjustable bed base can make a significant difference. Even a slight elevation of your knees takes pressure off your hips, and raising the head slightly reduces shoulder strain. Read more below.

A great mattress handles one dimension of comfort: the surface you sleep on. An adjustable bed adds a second dimension: the angle. Together, they solve side sleeping problems that neither can fix alone.

Reduced shoulder pressure. Elevating the head 10-15 degrees shifts some of your upper body weight away from the shoulder joint. Many side sleepers report that this small adjustment eliminates morning shoulder stiffness entirely.

Hip and lower back relief. Raising your knees slightly (the "zero gravity" position) takes tension off your hip flexors and reduces the curve in your lower spine. This is especially helpful for side sleepers who also experience back pain.

Independent adjustment for couples. If one partner is a side sleeper and the other is a back sleeper, a split king adjustable bed lets each person set their own angle. You can find your perfect side sleeping position without affecting your partner.

We evaluate mattresses based on four criteria specific to side sleepers: (1) pressure relief at shoulders and hips measured by owner reviews and sleep trial satisfaction rates, (2) spinal alignment based on construction and zoning design, (3) temperature regulation, and (4) compatibility with adjustable bases. We cross-reference Amazon ratings, owner reviews across multiple platforms, and expert assessments to build our rankings.
