How It Feels
The Cocoon by Sealy delivers a medium-feel sleep surface that works well for side and back sleepers. The comfort layer provides enough contouring to relieve pressure at the shoulders and hips, while the support core keeps the spine aligned. It's not the bounciest mattress, but it's not the slowest either.
Cooling is adequate for most sleepers. If you're a strict hot sleeper, a hybrid with more airflow may serve you better. But for average temperature regulation, the Cocoon by Sealy handles it well.
