Best Side-Sleeper Mattresses 2026: Picked by a Sleep Science Coach

Here are mattresses we liked for side sleepers, but weren't the best of the bunch.

Puffy Cloud for $949: The Puffy Cloud’s all-foam construction offers a softer feel to sleepers, but doesn’t overdo it so that spine alignment’s an afterthought. It does a good job of keeping pressure off the hips and shoulders for side sleeping, like a soft hug. —Julia Forbes

Casper The One for $999: We found that this all-foam mattress from Casper had a firmer feel and delivered on pressure relief, but not as well as the brand’s Dream Hybrid. Still, it’s a good option for those who want an affordable memory foam mattress that’s easy to move around. —Julia Forbes
