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.

Award-winning comfort, signature "just right" feel. It's a medium-firm feel and support.

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)

The Casper Original is good for sleepers of all kinds who want both support and cooling. Three layers of construction:

  • Breathable Polyurethane Foam
  • Zoned Memory Foam
  • Durable Polyurethane 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 layer of Airscape™ perforated breathable foam increases airflow and circulates air so you don't get too hot at night.

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.

Premium foam conforms to your body to relieve pressure.
Zoned Support™ provides a layer of memory foam with 3 ergonomic zones to help align your spine and provide more relief.
The durable base is engineered to prevent sinking and sagging while supporting your whole body.

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.

Stay cool all night with the innovative cooling system. AirScape™:

  • A top layer of perforated breathable foam helps reduce heat.
  • Tiny holes move hot air and body heat away.

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.

Get all-night comfort with the innovative support system. Zoned Support™:

  • 3 zones of targeted support for proper spinal alignment.
  • Softer foam around the shoulders provides more relief to the upper body.
  • Firmer foam under the hips, waist, and lower back helps align your spine.

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.

Planet-friendly textiles. Up to 57 recycled bottles in each cover.
