Side Sleepers Need Cushioning — But Not Too Much
The most common sleep position is side sleeping, and also the most likely to cause shoulder and hip pain if the mattress is too firm. Side sleepers need a mattress that cushions the shoulder and hip while keeping the spine aligned — not one that lets the body sink completely into the mattress.
Best Overall Soft: Helix Midnight
The Helix Midnight is medium feel (not ultra-soft) but it provides exceptional pressure relief at the hip and shoulder through its memory foam comfort layer. Motion isolation is excellent, and the pocketed coil core prevents full sinkage. Best-selling mattress for side sleepers in the sub-$1,200 range.
Best Ultra-Soft: Saatva Classic Plush Soft
For side sleepers who want genuine softness — the feeling of sinking into the mattress — the Saatva Plush Soft (3/10 firmness) delivers. The pillow top and additional comfort foam let the shoulder and hip sink in completely while the dual coil system prevents full collapse. Best for lighter side sleepers (under 160 lbs).

Best Soft Foam: Nectar Original
The Nectar Original has a slightly softer feel than the Premier and consistently rates well among side sleepers for its pressure relief at the hip and shoulder. Quilted cooling cover, gel memory foam, and 365-night trial make it an easy choice for side sleepers on a budget.
Best Soft Hybrid: DreamCloud Original
DreamCloud’s medium-soft cashmere blend cover and gel memory foam comfort layer provide excellent shoulder and hip cushioning. The innerspring core prevents the claustrophobic sinking-in feeling that some side sleepers experience with all-foam mattresses.
Firmness Target for Side Sleepers
Most side sleepers do best in the 3–5/10 range (soft to medium). Lighter side sleepers (under 130 lbs) may prefer 2–4/10. Heavier side sleepers (200+ lbs) often need 4–6/10 to prevent excessive sinkage despite the softer preference.

Frequently asked questions
What firmness is best for side sleepers? Medium-soft to medium — soft enough to let the shoulder and hip sink in while keeping the spine straight.
Memory foam or hybrid for side sleeping? Both work; memory foam gives more pressure-relieving hug, a plush hybrid adds support and bounce.
Will a firm bed hurt side sleepers? It can — too-firm beds create pressure at the shoulder and hip, leading to numbness and tossing.
