Mattress Construction

Materials Overview 4 layer foam construction:
  • The top layer is 1.5" of 3.5 lb. density Temperature Responsive Gel Memory Foam.
  • The 2nd layer is 1" of 3.0 lb. density foam.
  • The 3rd layer is 1.5" of 3.0 lb. density highly resilient foam.
  • The base layer is 7" of premium foam.
Comfort Info The 11" 4Sleep Mattress offers the most comfortable, supportive, and cooling sleep experience available. Each of the uniquely engineered foam layers have been specially designed to work together to keep the mattress at just the right comfort level so you can sleep better and live better.
Support Info Your mattress should feel like it's working for not against you. Our specially engineered foam maps to your body's unique pressure points as you move throughout the night, all while giving you the orthopedic support your body needs. Enjoy pain and pressure free sleep with the 4Sleep mattress.
Comfort Specs Achieving the ideal sleep temperature is no easy feat, and standard gel memory foam just won't do. We engineered a unique gel memory foam that dynamically both retains and liberates body heat to maintain an optimal sleep temperature range of 87° to 90° (30-32°C).
Support Specs Each of the layers of the 4Sleep mattress perfectly map your body's unique pressure points. The result is cloud like comfort and orthopedic support. Our foam formulations prevent your body from sinking, cratering or getting "stuck" in your mattress. With 4Sleep you'll toss and turn noticeably less, which means an incredibly restful sleep experience.
Sleep edge-to-edge without the fear of rolling off. Unique to the 4Sleep Mattress, our support system resists over-compression and is designed to gently nudge you back from the edge. Most other memory foam mattresses sink to the baseboards when you sit on the side. Or they leave you feeling like you'll roll off of it if you get too close to the edge. You can stretch and sleep on the entire surface of the 4Sleep mattress.
Fabric Specs Our cover is like a performance shirt fabric, it wicks away moisture, is breathable, lightweight, and has "Cooling On Demand" technology that actually has built in gel to help keep you cool.
