This 12-inch medium memory foam mattress is designed to provide you with a cooler, more comfortable night's sleep. It features three layers of foam, including a top layer infused with CopperChill technology that helps regulate temperature and wicks away moisture. The middle layer offers adaptive support that conforms to your shape, distributing your weight evenly to relieve pressure points so you wake up feeling refreshed. Plus, this mattress comes with a removable, machine-washable cover for easy care.

Mattress is really wonderful. The 12” high fits perfectly on my bed and I got a great night’s sleep. The memory foam kind of “hugs” you a bit and pulls you in, and that’s a terrific feeling. Recommend.. Randall. Sonoma, CA. Fri May 23 2025
