Mattress Construction | |
Materials Overview | |
Three layer construction:
| Whether you prefer a firm or a softer experience, our hybrid mattresses play with varying layers of foam, natural latex and our pocket coil system.
|
Comfort Info | |
Traditional memory foam is made from dense material, so it traps your body heat and can make you sweaty and uncomfortable while you're in bed - and who can sleep like that? | With reduced motion transfer, you and your partner can experience an uninterrupted night's sleep for your perfect sleepy sanctuary. |
Support Info | |
Our Bio-Core® foam support layer won't sag even after decades of use. And, like our Bio-Pur® foam, it's partially made from plants instead of petroleum so it's eco-friendly. | The various blend of ingredients deliver the perfect amount of body contouring and pressure relief with extra soothing support. The Infinity Foam top layer is our unique material that prevents heat retention for a cooler night's sleep, and gives the perfect balance of support, contouring, and pressure relief in all the right places. This is our finishing touch to give you an unparalleled indulgent experience. |
Comfort Specs | |
The HIVE® transition layer has precision-cut channels that carry away even more heat and moisture. It's enough to make you feel like you're weightlessly resting on a cloud. | Our unique foam construction provides contoured support & breathability for the coolest night's sleep. |
Support Specs | |
Bio-Pur® contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night. | Our edge-to-edge pocket coil system was created to provide superior edge support. Each coil is individually wrapped so it can compress and expand independently, providing you with pressure relief where you need it most. The coils are positioned between layers of foam to allow you to feel like you're floating on air. |
