Firmness info

The Cocoon Chill is a medium firmness, about a 6 on the firmness scale. We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a mattress with our Perfect Fit memory foam that adapts to your unique body size, shape and sleep position.

It rates as a medium-firm mattress, but really combines the best of both firm and soft products. It's the perfect balance of comfort and support. Our provides superior pressure relief, with little bounce, and zero motion transfer. Essentially you feel like you're floating on a cloud. Unlike other memory foam mattresses, we sped up our foam's response rate so that you don't sink too far down into the core, and so you don't feel stuck in the foam.

ComfortA top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model. Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.Four layers of high-density memory foam, refined through two years of R&D and 27 rounds of prototyping to provide the perfect balance of comfort, support, responsiveness, and breathability. Zero motion transfer. To keep our mattress from overheating, we developed an extraordinary new foam called 3BELOWย™. 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.
SupportOur high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you. Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.Our four-layer weightless foam system combines a plush top layer with increasingly firmer base layers, to deliver an optimal combination of comfort and support. We refined our mattress through 27 rounds of testing, optimizing for pressure-relief at all five key pressure points. We tested a range of body types and sizes, ensuring that the W1.27 would be supremely comfortable for almost all people, while still providing full body support. The core of our W1.27 is 100% viscoelastic memory foam. We tested every possible material, including memory foam, latex foam, coils, coil / foam hybrids, hand-rolled cotton, horsehair, and found that memory foam gives us the greatest precision in crafting a truly great product. We've made the best memory foam mattress on the market. The W1.27 achieves unparalleled balance, meaning that it's supremely comfortable to lay on, but also provides better body support than other products.
