This firm hybrid mattress starts with a support layer of wrapped coils that responds independently to your movements for customized spinal alignment and reduced disturbances from restless partners. A layer of comfort foam on top provides pressure relief like memory foam, but without that sink-in feeling. Made with Certi-PUR US® certified foams, this hybrid mattress guarantees the highest quality and no harmful chemicals where you sleep. It’s expertly compressed, packed, and shipped to you in one convenient box—along with a 10-year limited warranty for added peace of mind.
