SUPPORT MEETS SOFTNESS: The 12” AS3 Hybrid offers the perfect blend of support, softness, and bounce. That’s why it’s our most popular hybrid mattress for every type of sleeper.
DEEPER SLEEP: The FDA-determined Celliant cover promotes more restful sleep and faster recovery. It works by reflecting heat back into your body as infrared light, which increases local circulation.
COOLING PRESSURE RELIEF: The Bio-Pur comfort layer features an open-cell design. It wicks away warm air to keep you cool all night. And it conforms to your body to relieve pain-causing pressure points. But it also bounces back fast — so you never feel "stuck. "
POCKET-COIL BASE FOR MORE BOUNCE: The AS3 Hybrid gets its support from up to 900 pocket-coil springs. They give the mattress more bounce, similar to a traditional innerspring mattress. But the pocket-coils also help minimize motion transfer. Plus the perimeter of the pocket-coil layer is enclosed with sturdy foam for better edge support making it easier to get in and out of bed.
TARGETED LOWER BACK SUPPORT: The pocket-coil layer in the AS3 Hybrid features Amerisleep’s proprietary zoned-support system. The coils located under your lower back overlap to provide more support for extra comfort and pain relief.
The 12” AS3 Hybrid — or AS3h — is Amerisleep’s most popular hybrid mattress. It offers the perfect blend of support, softness, and bounce. The AS3h features a Bio-Pur comfort layer with an open-cell design. Bio-Pur contours to your body to relieve pain-causing pressure points and keeps you cool. Plus it bounces back fast, so you never feel “stuck” if you change sleeping positions. The AS3h also provides gentle support with more bounce using a layer of up to 900 pocket-coil springs. And the spring layer features our proprietary targeted support system. It creates three comfort zones for extra comfort and pain relief, and delivers 25% more support for your back. For edge support, we added firm foam to the perimeter of the pocket-coil layer making it easier to get in and out of bed. On top of that, the AS3h is wrapped in a cover with FDA-determined Celliant technology. Celliant reflects heat back into your body as infrared light, which increases local circulation for deeper sleep and faster recovery.
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

I have spent most nights on my Sleep Number Memory Foam Hybrid changing postions hourly as I woke up in pain between previous injuries to my neck, back and shoulder. I never experienced a truly deep uninterrupted night sleep. Three of my colleagues had been bragging about the amazing sleep they were getting on their new Amerisleep AS3 Hybrid matresses. After investigating reviews and being amazed by the price, The 100 day sleep guarantee provided all the incentive I needed to try it. From day one I experienced deep , uninterrupted and pain free sleep for the first time in years on my new King size AS3 Hybrid. The price was so reasonable I even purchased a top of the line adjustable base to go with it. When I unboxed my new AS3 mattress I was amazed as I watched it expand in front of me. The thickness of the matress and cool to the touch surface was exactly what I needed at a fraction of the price I paid for my old Sleep Number bed. I have never woken up so refreshed and ready to go.
