Firmness Info

The AS3 is our most versatile mattress. It evenly blends support and softness, so it's great for people who change positions as they sleep and couples with different sleep styles. It's also our most popular mattress overall.

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.

Mattress Construction

Materials Overview

Three layer construction:

  • Bio-Pur® foam
  • HIVE® transition layer
  • Bio-Core® foam support layer
  • Refresh Cooling Cover.
Now available in a Hybrid (no HIVE layer but with a foam-encased pocket springs layer, see the AS3 Hybrid)

3 layer construction:

  • Perfect Fit Memory Foam
  • Personalized Comfort Layer
  • Support 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.

A 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.

Support Info

Our Bio-Core® foam support layer won't sag even after decades of use. And, like our Bio-Pur® foam, it's partially made from plants instead of petroleum so it's eco-friendly.
The HIVE® 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 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.

Comfort Specs

The HIVE® 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-Pur® material features an advanced-open cell design. This makes Bio-Pur® more breathable and responsive than memory foam, which will keep you cool and comfortable all night. Plus we make Bio-Pur® from partially plant-based sources using a zero-emission process. That means it's the most eco-friendly material of its kind.

Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.

Support Specs

Bio-Pur® contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night.
Our HIVE® 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.

Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.

Fabric Specs

Refresh Cooling Cover
The Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest compared to a traditional 100% polyester cover. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy. This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep.

Our premium stretch-knit cover is infused with a proprietary "Phase Change Material" that absorbs and dissipates heat for a refreshing, cool to the touch surface.
