The Cocoon by Sealy Medium Hybrid is a 12-inch mattress-in-a-box that pairs gel memory foam with fabric-wrapped coils and a reinforced Quantum Edge steel perimeter. It is aimed at adult sleepers who want a medium feel with more airflow and easier movement than an all-foam bed. Against rivals, the edge support and cooling foam are its main selling points; the trade-off is that it is a bed-in-a-box hybrid, not a traditional innerspring or a premium coil mattress.

This is a 12-inch medium hybrid mattress that ships in a box. It combines gel memory foam with supportive fabric coils. The coils allow increased airflow and limit motion transfer. A core support layer is powered by Active Support Technology.
A Quantum Edge steel perimeter reinforces the edges. This helps the mattress feel larger and makes getting up easier. The mattress accommodates all adult sleepers.
The soft stretch-knit cover is made with spun poly fibers and has Surface-Guard Technology. It is breathable. The mattress includes Moisture Protect and can be spot-cleaned and air-dried.
