Sleep in perfect alignment

Our HIVE® transition layer gives your body targeted support to ease tension and help you sleep in perfect alignment. It provides added support under your head, back, and legs. And it gives your shoulders and hips extra cushion. We’ve also designed HIVE® to reduce pain-causing pressure points.

Zone system offers more lower back support for extra comfort and pain relief

Amerisleep’s proprietary zoned-support system features three comfort zones. It delivers more support for your back, and offers more cushion above the shoulders and below the hips. That helps keep your body aligned, resulting in more comfortable sleep with less pain.

Frequently asked questions

 
What does the Amerisleep AS3 feel like?

The AS3 gently contours to your whole body, with targeted support for your back.

 
Do I have to flip or rotate my mattress?

No, we use durable materials designed to last for decades. They won’t sag or develop soft spots, and the ultra-breathable white should always face upward.

 
What kind of bed sheets should I use with my mattress?

Thick sheets can trap heat and reduce the breathability of our mattresses. We recommend you pair your Amerisleep mattress with our luxurious and breathable bedding.

 
Where can I try the Amerisleep AS3?

The best place to try a new mattress is in your own home. That’s why we offer a risk-free, 100-night trial. It lets you experience the best your mattress has to offer, and if you don’t love it we’ll give you a full refund.

But if you do want to try the Amerisleep AS3 in person, you can visit one of our retail locations. (You’re still covered by the 100-night trial, even if you order in one of our stores.)
