Enjoy the therapeutic comfort of a visco memory foam mattress with the Sleep Science 10” Memory Foam Mattress. The mattress has 3-inches of Sleep Science premium visco memory foam comfort layer with medium/firm support. It relieves pressure points with its top layer of visco memory foam, yet supports body weight with its supportive base foam.

This 10" mattress features the Sleep Science patented wedge, edge to edge support system, which increases and stabilizes the sleep surface, offers 20% more sleep surface and extends the life of the mattress.

The Sleep Science 10" also features a 2" air comfort layer in the middle of the mattress. The air comfort layer is made of an enlarged cellular material to allow the flow of air between the top and bottom layers of the mattress to neutralize the temperature of the mattress as it absorbs body heat. This ensures optimized comfort throughout your sleep experience. The mattress is covered in a soft velour jacquard fabric.
