The ergonomic zones of this mattress are great for side sleepers (most of us, it turns out!). As Cary pointed out, those who sleep on their side will want to be mindful of their sleep posture because this position can easily strain the back and hips. Casper’s Nova Hybrid zones (soft under the head and feet and firmer under the shoulders, hips, waist, and lower back for a more comfortable fit) can help keep you in good sleep form.This mattress has a cushy feel, well suited for side sleepers seeking a softer bed. It’s made of a combination of polyurethane foam and memory foam (we’d prefer to see natural latex, but Casper at least tests its foam for emissions).
