Amerisleep AS1 vs Amerisleep AS2

The AS1 is our firmest mattress, it offers gentle-but-firm support that stays cool all night. It's a great choice for back and stomach sleepers who like extra support.

The AS2 is our medium-firm mattress, and it's our most popular with back and stomach sleepers. It's thicker than the AS1 and contains a transition foam layer, giving it slightly more cushion.

Two layer construction:

• Bio-Pur® foam
• Bio-Core® foam support layer
• Refresh Cooling Cover.

Medium-firm mattress is engineered to facilitate healthy spinal alignment. Verywell Health even calls it the best mattress for back pain. If you're a back or stomach sleeper, the AS2 is perfect for you. Three layer construction:

• Bio-Pur foam
• HIVE transition layer
• Bio-Core foam support layer
• Refresh Cooling Cover.

Our foam is also better than traditional memory foam because it recovers its shape faster. With a typical foam mattress, you often wind up "stuck" when you change positions but the mattress is still holding your previous shape. That's because it takes around 60 seconds for the foam to bounce back.
Ours bounces back in just four seconds, so as you move at night your mattress keeps up with you, providing superior comfort.

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.

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 Bio-Pur® foam is five times more breathable than traditional memory foam, because of its advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.

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.

Bio-Pur® breathes and conforms to your body. When you lie down, you'll feel Bio-Pur® relieve your pressure points.

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.

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.
