Which Is Better For Your Sleep Style?

Side sleepers
Spec not available

Pressure-relief data not available for one or both mattresses — spec not available.

Stomach sleepers
Cocoon by Sealy Chill Hybrid

Firmer at 5.5/10 vs 5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
