The Perfect Sleeper Oasis Sleep 12-inch extra firm mattress is built for sleepers who like a steadier, more supportive feel. Its extra-firm comfort helps you stay lifted, while still providing contouring at the surface for a more comfortable settle-in.


At the core, a 3-zoned coil design is crafted to help balance support and pressure relief across key areas of the body. Above it, Cool Twist Gel Memory Foam adds conforming comfort that follows your shape without taking away from the extra-firm character of the bed.


If you want to fine-tune your sleep setup, upgrades are available with additional cooling layers and support. With Perfect Sleeper, we make sleep easy.
