The perfect balance of comfort, support, and bounce

To provide a great night’s sleep, your mattress has to be in the sweet spot: soft enough to be comfortable, yet fully supportive, and also responsive enough. We tested our foam system through 27 iterations, using real pressure-mapping and force-resistance data to identify the optimal balance to help you sleep more deeply.


Breathable and cool

To keep our mattress from overheating, we developed an extraordinary new foam called 3BELOW™. It’s a fully breathable, open-cell material, infused with heat-conductive gel particles. That means it actually draws heat from your body and disperses it throughout the mattress so it escapes more quickly.

As a result, the W1.27 sleeps three degrees cooler than other foam mattresses, right in the sweet spot for deep, uninterrupted sleep.

Built on real sleep data

To ensure our products actually perform better, we recruited an army of testers and tracked their sleep, night after night, for more than two years. We tracked sleep quality through 27 rounds of testing, continually refining our product until it delivered deeper and better sleep than anything else.
