Firmness Info

The AS5 is our softest mattress. It wraps you in plush comfort that stays cool all night. But it also bounces back fast, so you never feel stuck.

If you already know that you love a soft or firm mattress then follow your heart. However, if you are unsure you can follow this quick guide to make a selection:
1. Back Sleepers and Stomach Sleepers should choose the Firm Mattress
2. Side Sleepers and 'Free Style' Sleepers should choose the Soft Mattress
3. If either you or your partner is heavier than 220 lbs, the Firm Mattress may be the option for you.
4. If you are lighter than 130 lbs, the Soft Mattress may be the option for you.

Mattress Construction

Materials Overview

For anyone seeking the ultimate in softness, this is the bed for you. Four layer construction:

  • Bio-Pur® foam
  • Active Flex 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 AS5 Hybrid)

Whether you prefer a firm or a softer experience, our hybrid mattresses play with varying layers of foam, natural latex and our pocket coil system.
Firm:

  • 1" Cooling Infinity Foam
  • 2" Responsive Natural Latex
  • 8" Edge-to-Edge Coil System
  • 1" High Density Support Foam
Soft:
  • 2" Cooling Infinity Foam
  • 1" Hybrid Transition Foam
  • 8" Edge-to-Edge Coil System
  • 1" High Density 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.

With reduced motion transfer, you and your partner can experience an uninterrupted night's sleep for your perfect sleepy sanctuary.

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.

The various blend of ingredients deliver the perfect amount of body contouring and pressure relief with extra soothing support. The Infinity Foam top layer is our unique material that prevents heat retention for a cooler night's sleep, and gives the perfect balance of support, contouring, and pressure relief in all the right places. This is our finishing touch to give you an unparalleled indulgent experience.

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.

Our unique foam construction provides contoured support & breathability for the coolest night's sleep.

Support Specs

Active Flex adds extra softness to the AS5, without sacrificing support. It cradles you the instant you lie down and it rebounds in seconds if you shift positions.
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.

Our edge-to-edge pocket coil system was created to provide superior edge support. Each coil is individually wrapped so it can compress and expand independently, providing you with pressure relief where you need it most. The coils are positioned between layers of foam to allow you to feel like you're floating on air.

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.
