The first mattress specifically engineered to deliver better sleep.

We launched an unprecedented sleep study, tracking testers' sleep, night after night, for more than two years. We went through 27 rounds of prototyping, researching and testing new materials to improve sleep performance. We developed our new polymer-reinforced ZeroGravity foam for improved responsiveness, and our new gel-infused 3Below foam to prevent overheating.

We then endlessly tested and refined all components, developing a foam system with optimally balanced comfort, support, responsiveness, and temperature, to deliver a better night's sleep.

Four precisely tuned layers combine to form a perfectly balanced foam system

Ultra high-density memory foam provides ultimate comfort, infused with heat wicking gel particles to conduct heat away from your body.

Two middle layers of our proprietary Zero Gravity foam, polymer-reinforced for improved responsiveness, provides bounce and support.

High-density base layer provides additional structural support and durability.

The fabric shell is removable for easier cleaning, with ventilated corners for improved breathability, and a quilted top surface for additional airflow between sheets and mattress.
Free shipping & installation - we'll set up your new mattress, and can haul your old one away for recycling if you don't want it anymore.

Risk-free 120-night trial - you've got four months to try things out. If you're not happy, for any reason, we'll pick up the mattress at our expense and refund 100% of your money, no questions asked.

15 year guarantee - if you notice any change in the performance of your mattress, such as sagging, softening, or dents, we'll replace it with a new one, free of charge.
