Best Side-Sleeper Mattresses 2026: Picked by a Sleep Science Coach
SOURCE:Wired|BY:Martin Cizmar, Julia Forbes
We’ve tested hundreds of the top hybrid, memory foam, and cooling mattresses to find the best combination of support and pressure relief.
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
