Firmness Info The AS4 is our medium-soft mattress. It offers plush comfort with targeted support that helps you sleep your best. Plus it stays cool all night, making it our most popular model with side sleepers. 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.

Mattress Construction
Materials Overview Three layer construction:
  • Bio-Purยฎ foam
  • HIVEยฎ transition layer
  • Bio-Coreยฎ foam support layer
  • Celliantยฎ cover.
 4 layers of construction:
  • 1.5" 4lb Density 10 ILD 3Below Gel-Infused Memory Foam
  • 2" 3lb Density 18 ILD Polymer-Reinforced ZeroG Foam
  • 1.5" 5lb Density 20 ILD Polymer-Reinforced ZeroG Foam
  • 6" 1.8lb Density 30 ILD Base Foam.
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?
We developed our foam with an enhanced "open cell structure", which means there is more air space between the foam particles. That space wicks away heat while you sleep, and can keep you cooler and more comfortable. 		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.
Support Info Our Bio-Coreยฎ foam support layer won't sag even after decades of use. And, like our Bio-Purยฎ foam, it's partially made from plants instead of petroleum so it's eco-friendly.
The HIVEยฎ layer features hundreds of foam hexagons grouped into five comfort zones. Each zone is designed to provide extra cushion where you want it and support where you need it. That way your body gets the support it needs to stay properly aligned, so you can sleep your best. 		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.
Comfort Specs The HIVEยฎ 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.
Amerisleep's Bio-Purยฎ material features an advanced-open cell design. This makes Bio-Purยฎ more breathable and responsive than memory foam, which will keep you cool and comfortable all night. Plus we make Bio-Purยฎ from partially plant-based sources using a zero-emission process. That means it's the most eco-friendly material of its kind. 		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.
Support Specs Bio-Purยฎ contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night.
Our HIVEยฎ transition layer provides targeted support and pressure relief so you can sleep in perfect alignment. It gives your head, back, and legs more support, and your shoulders and hips more cushion. 		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.
Fabric Specs High-Performance Celliantยฎ Cover
Celliantยฎ is an advanced fabric that is both soft and ultra-breathable to keep you sleeping your best each and every night.
