Side sleeping is the most common sleeping position — roughly 60% of adults sleep primarily on their side — and it’s generally considered one of the healthiest positions for spinal alignment and breathing. But side sleeping also creates unique challenges for mattress selection. When you lie on your side, your body weight concentrates on two relatively narrow areas: the shoulder and the hip. These are the widest points of your body, and they need to sink into the mattress enough to keep your spine straight. A mattress that’s too firm creates painful pressure points at the shoulder and hip. A mattress that’s too soft lets the hips sink too deep, curving the spine and causing lower back pain.
As an ergonomics specialist, I evaluate mattresses specifically for how well they handle this side-sleeping challenge. The ideal mattress for side sleepers provides deep pressure relief at the shoulders and hips while maintaining enough support through the midsection to keep the spine in a neutral, straight line. Here are the mattresses that do this best.
Helix Midnight Luxe<br />
Our Top Picks
1. Helix Midnight Luxe — Best Overall for Side Sleepers
The Helix Midnight Luxe was designed with side sleepers as the primary audience, and it shows. The zoned coil system uses softer coils in the upper third (shoulder zone) and firmer coils in the center third (hip and lumbar zone). This means your shoulders sink in for pressure relief while your hips receive enough support to maintain spinal alignment — exactly what side sleepers need.
The quilted pillow top adds a plush comfort layer that cushions the shoulder and hip without the excessive sinking of thick memory foam. The gel memory foam comfort layer contours to your body’s curves, and the Tencel cover is breathable and moisture-wicking. At 14 inches tall with a medium feel (about 5.5-6/10), it provides the cushioning that side sleepers need without feeling too soft for occasional back sleeping.
Motion isolation is excellent — the individually wrapped coils and foam layers absorb movement effectively, so you won’t be disturbed by a partner’s movements. Edge support is strong for a hybrid, with reinforced perimeter coils that prevent the roll-off feeling some side sleepers experience near the edge of the bed.
2. Nectar Premier — Best Memory Foam for Side Sleepers
Memory foam is inherently well-suited for side sleepers because it contours closely to the body, distributing weight evenly and eliminating the pressure points that cause shoulder and hip pain. The Nectar Premier takes this further with a 3-inch gel-infused memory foam comfort layer that provides deep contouring without the excessive heat retention of traditional memory foam.
The medium-firm feel (about 6/10) is slightly firmer than some side sleepers prefer, but the memory foam’s contouring ability compensates — it feels softer than the firmness rating suggests because it molds to your body rather than pushing back. Side sleepers under 200 lbs will find the pressure relief excellent. Heavier side sleepers may want to consider the Nectar Premier Copper, which adds a copper-infused layer for additional support and cooling.
At $949 for a queen during frequent sales (MSRP around $2,382), the Nectar Premier offers premium memory foam performance at a competitive sale price. The 365-night trial gives you a full year to evaluate, and the lifetime warranty provides long-term coverage.
3. WinkBeds EcoCloud — Best Latex for Side Sleepers
The WinkBeds EcoCloud uses natural Talalay latex as its primary comfort material, which provides a different feel than memory foam — more responsive, bouncier, and naturally cooler. For side sleepers who find memory foam too “sinky” or too warm, latex offers excellent pressure relief with a more buoyant feel. The EcoCloud’s medium feel (about 5.5/10) is well-suited for side sleeping, allowing adequate shoulder and hip sinking while maintaining support.
The construction includes a 4-inch Talalay latex comfort layer, a transitional poly foam layer, and individually wrapped coils. The organic cotton cover and natural latex make this one of the more eco-friendly options available. Talalay latex is also naturally hypoallergenic and resistant to dust mites — a benefit for allergy sufferers.
At $1,599 for a queen, the EcoCloud is priced in the premium range. The 120-night trial and lifetime warranty are included. If you prefer a natural, responsive feel over the conforming hug of memory foam, this is the best option for side sleepers.
4. Brooklyn Bedding Signature Hybrid — Best Value for Side Sleepers
The Brooklyn Bedding Signature Hybrid delivers impressive side-sleeper performance at a price that undercuts most competitors. The construction uses a quilted top with gel memory foam, a comfort foam transition layer, and individually wrapped coils. It’s available in three firmness options — Soft (4/10), Medium (6/10), and Firm (7.5/10) — and side sleepers should choose the Soft or Medium option depending on body weight.
The Soft option is particularly well-suited for side sleepers under 180 lbs, providing deep pressure relief at the shoulders and hips. The Medium option works better for side sleepers between 180-230 lbs who need a bit more support to prevent excessive hip sinking. The gel memory foam comfort layer provides good contouring, and the coil base adds responsiveness and airflow that all-foam mattresses lack.
At $665 for a queen (frequently on sale for $532), the Signature Hybrid is one of the best values for side sleepers. The 120-night trial and 10-year warranty are standard for the price range.
5. Nolah Signature — Best for Shoulder Pain
The Nolah Signature uses proprietary AirFoam that the company claims provides better pressure relief than traditional memory foam while sleeping cooler. In practice, the foam does feel different — it’s more responsive than memory foam with less of the slow-sinking feel, and it does seem to sleep slightly cooler. For side sleepers with shoulder pain specifically, the Nolah Signature’s comfort layer provides excellent contouring around the shoulder area.
The construction includes a 2-inch AirFoam comfort layer, a high-resilience foam transition layer, and a high-density foam base. The medium feel (about 5.5/10) is well-calibrated for side sleeping. The mattress is 12 inches tall and ships compressed in a box.
At $999 for a queen (frequently on sale for $749), the Nolah Signature is competitively priced. The 120-night trial and lifetime warranty provide good coverage.
What Side Sleepers Need in a Mattress
Pressure Relief at Shoulders and Hips
This is the most critical factor. When you lie on your side, your shoulder and hip bear most of your body weight on a relatively small surface area. The mattress needs to allow these areas to sink in enough to distribute the pressure evenly. Insufficient pressure relief causes numbness, tingling, and pain that disrupts sleep and causes you to toss and turn.
Spinal Alignment
While the shoulders and hips sink in, the mattress needs to support the waist and midsection to keep the spine straight. If you imagine looking at a side sleeper from behind, the spine should form a straight horizontal line from the neck to the tailbone. If the hips sink too deep (mattress too soft) or the shoulders don’t sink enough (mattress too firm), the spine curves and lower back pain results.
Firmness Range
Most side sleepers do best with a medium to medium-soft mattress (4-6 on a 10-point scale). The exact firmness depends on body weight:
- Under 130 lbs: Soft to medium-soft (3-5/10) — lighter bodies don’t compress mattresses as much, so a softer surface is needed for adequate pressure relief
- 130-200 lbs: Medium (5-6/10) — the standard range that most mattresses target
- Over 200 lbs: Medium to medium-firm (6-7/10) — heavier bodies compress mattresses more, so a firmer surface prevents excessive sinking while still providing pressure relief
Pillow Considerations for Side Sleepers
Your pillow is just as important as your mattress for side sleeping. Side sleepers need a thicker, firmer pillow than back or stomach sleepers to fill the gap between the shoulder and the head, keeping the neck aligned with the spine. A pillow that’s too thin lets the head drop, straining the neck. A pillow that’s too thick pushes the head up, creating the opposite strain. Look for pillows with a loft of 4-6 inches for most side sleepers.
Frequently Asked Questions
Is memory foam or hybrid better for side sleepers?
Both work well, but they feel different. Memory foam provides deeper contouring and better motion isolation — ideal if you want maximum pressure relief and share the bed with a restless partner. Hybrids provide a more balanced feel with better responsiveness, edge support, and airflow. If you sleep hot, a hybrid is usually the better choice. If pressure relief is your top priority, memory foam has a slight edge.
Can side sleepers use a firm mattress?
Generally, no. Firm mattresses (7-10/10) don’t allow enough sinking at the shoulders and hips for proper side-sleeping alignment. This creates pressure points and spinal misalignment. Some heavier side sleepers (over 250 lbs) may need a medium-firm mattress (6-7/10), but truly firm mattresses are best suited for stomach sleepers and some back sleepers.
Why do my shoulders hurt when I sleep on my side?
Shoulder pain during side sleeping is almost always caused by a mattress that’s too firm, a pillow that’s the wrong height, or both. The shoulder needs to sink into the mattress to avoid bearing excessive pressure. If your mattress doesn’t allow this, the shoulder joint is compressed all night, causing pain and stiffness. Switching to a softer mattress or adding a mattress topper can often resolve this.
Should I put a pillow between my knees?
Yes — a pillow between the knees is one of the most effective and free improvements for side sleepers. It keeps the hips aligned, reduces strain on the lower back, and prevents the top knee from pulling the spine out of alignment. A regular pillow works, but contoured knee pillows ($15-30) are shaped to stay in place throughout the night.
The Bottom Line
Side sleepers need mattresses that prioritize pressure relief at the shoulders and hips while maintaining spinal alignment through the midsection. The Helix Midnight Luxe’s zoned support system is the most targeted solution, with softer coils where you need cushioning and firmer coils where you need support. The Nectar Premier is the best memory foam option for deep contouring. The Brooklyn Bedding Signature Hybrid offers the best value with three firmness options. Whichever you choose, aim for medium to medium-soft firmness, pair it with a properly-sized pillow, and consider a knee pillow for optimal alignment.
