Amerisleep AS1 vs OkiFirm

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 OkiFirm is an 8/10 on the firmness scale.

Two layer construction:

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

The OkiFirm is a 2 layer construction:

• Cooling Ice Yarn Cover
• 3" Graphite Foam (Density 2.8 lb, ILD 12)
• 7" High Density PU Foam (Density 1.5 lb, ILD 36).

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.

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 OkiFirm's graphite foam provides firm support to keep your body in its desired position and help with back and spine alignment without leaving you feeling like you are floating on top of the mattress. Our densest foam layers provide comfortable but solid support with little give to protect from unwanted contouring.

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.

Ice Yarn cover is cool to the touch, while the graphite foam with air holes creates a breathable, heat-removing mattress that lets cool air flow so you never overheat.

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

High-grade graphite foam provides exceptional support while not sinking as much as memory foam.
High-density PU foam provides the proper support needed and is the perfect base layer to pair with the Graphite Foam.

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.

Ice Yarn Zip Cover. This hypoallergenic cover is cool to the touch to help regulate body temperature and prevent you from overheating. The cover is easy to remove and machine washable.
