The AS3 is our most popular and versatile mattress. It evenly blends support and softness, so it’s great for people who change positions as they sleep. We combine our proprietary Bio-Pur® and HIVE® comfort layers to create a soft but responsive feel that relieves pressure points and makes you feel like you’re floating. Plus the FDA-determined Celliant® cover increases local circulation for faster recovery and more restful sleep.
A vey supportive mattress for my severe back problems; I now get a most restful sleep and a longer one
I purchased the AS3 earlier this summer and my sleep has improved dramatically since.

Celliant® is an advanced fabric made with 13 thermoreactive minerals that helps improve the performance of the mattress.
Our Bio-Pur™ foam is five times more breathable than traditional memory foam, because of it’s advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.
The affinity transition layer is soft and responsive. It reacts to your body position to evenly support your weight and can help relieve pressure points, so it feels as if you’re weightlessly resting on a cloud.
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.
Amerisleep mattresses are expertly designed to help you get more sleep — guaranteed. Our mattresses are built with performance in mind down to the last detail. That even includes the cover, which is a critical part of a mattress because it's the layer closest to your body when you sleep.
Amerisleep is officially licensed to use Celliant® in our covers. This advanced fabric combines 13 minerals into thermoreactive yarn that converts body heat into infrared.
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. Remember, you have 100 nights to try it for yourself - if you don't love it, give us a call and we'll pick up the mattress and refund you completely!
On top of that, our foam is also the most environmentally friendly. Our patented foam-making process uses plants to replace some petroleum, and is the only manufacturing method that exceeds the standards of the Clean Air Act.
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.
Was skeptic but glad I purchased :)
This company was easy to work with and delivered everything they promised and more. Unusual these days thanks amerisleep

No furniture, no problem. You can put your Amerisleep mattress directly on the floor.
If you want to use your existing box spring, place a piece of 3/4” moisture resistant plywood directly on top. Or you can shop our Amerisleep Foundation.
A flat platform will work perfectly, so long as the gaps between the slats are no more than three inches apart.
Adding an adjustable base can elevate your comfort, allowing you to read or watch tv in bed.
Imagine waking up each morning with no pain and increased energy. How would that change the way you approach your day? Would you finally be able exercise regularly? Would you be able to perform better at work instead of constantly feeling groggy and needing another cup of coffee?
Sleep quality is so important because we spend about a third of our lives in bed!
That means, besides our jobs and our families, our sleep probably has the biggest impact in our quality of life. The number of daily problems that go away with a good night’s sleep is astounding — but that only happens if you actually do something to improve your sleep.
If you just keep things the same, you’ll keep getting the same disappointing results. And don’t you deseve better?

Every mattress is protected by a 20 year warranty so you can rest easily. We offer full repair or replacement for the first 10 years and a pro-rated warranty for the last 10 years of your mattress’ life if it is judged to be defective due to workmanship or structural defects. This does not cover a normal increase in softness or decrease in the slow recovery of the mattress as these don’t affect the pressure-relieving qualities of the mattress. Learn more about how our warranty protects you on our Warranty Information page.
Back to FrontI'm usually a budget shopper but there are some things you cant skimp on. I have had neck back and shoulder problems for years. I knew I needed a good mattress. I read so many reviews of this mattress/company and people saying they had less pain. I 100% agree! I feel so much better when I wake up. Makes getting out of bed harder for myou husband he's been sleeping longer!

Amerisleep is one of the most eco-friendly mattress companies. From the way we make our foam all the way through how it arrives at your door, we work hard to use processes that are sustainable — literally from start to finish.
First, our patented Variable Pressure Foaming (VPF) process allows us to use plant-based materials to replace some petroleum, so it's better for the environment. It also reclaims and recycles any waste, so there is no air pollution. It's the only process for making foam that meets the Clean Air Act's standards.
Once we've made your mattress, we pack it up in a box made from post-consumer materials before shipping it to your door. Being more eco-friendly is just one more thing that makes our mattresses different than our competitors.

delivery
Your mattress ships to you compressed in an eco-friendly box small enough that we can use FedEx. That means it gets to you quickly, usually within a week of your purchase!
I love the AS3 Bed.
After 12 years on our old mattress, we splurged in Amerisleep and am so glad we did. Back and neck pain gone!
