Allswell Supreme vs Amerisleep AS1

That just-right medium-firm feel. Rated a 4.5 to 6.5 on the very unscientific firmness scale.

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 Supreme mattress by Allswell is the best in their lineup, constructed of the following layers:

• Quilted Cover + Euro Top
• Graphite & Copper Gel Infused Memory Foam
• Energex™ Foam
• Quantum Edge Individually Wrapped Coils.

Two layer construction:

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

Stay asleep with individually-wrapped coils which help minimize motion transfer.

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.

Two-sided edge support with Reinforced Quantum Edge - use the whole sleeping surface and easily get in and out of the bed.

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.

Cooling graphite and copper gel layer absorbs and transfers heat away from the body.

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.

Energex™ foam provides pressure relief over a wide range of temperature.

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

Quilted top panel woven with our signature A. This is a Euro top mattress with two layers of high-performance memory foam underneath its plush quilted surface which makes for a supreme sleep experience.

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.
