The AS2 is our medium-firm mattress, and it’s our most popular with back and stomach sleepers. It’s thicker than the AS1 and contains a transition foam layer, giving it slightly more cushion. We blend our proprietary Bio-Pur™, Affinity with SMT, and Bio-Core™ foam layers to provide comfortable but stable support. Plus the Celliant® cover is made with thermoreactive yarn to safely turn body heat into infrared. You'll love it, guaranteed.

High-Performance Celliant® Cover

Celliant® is an advanced fabric made with 13 thermoreactive minerals that helps improve the performance of the mattress.

Extra-Breathable cooling layer

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.

Enhanced "Feels-like-you're-floating" layer

The Affinity layer with Surface Modification Technology (SMT) is our ergonomic transition foam. It has “zones” that provide extra pressure relief in key areas like the shoulders and lower back, along with precision-cut channels that carry away even more heat and moisture. It’s enough to make you feel like you're weightlessly resting on a cloud.

Sag-free & Eco-friendly Support

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.

Tested to get you more sleep.

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.

We created a superior memory foam that helps keep you cool.

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.

More comfort. Less “stuck”.

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.


Amazing Bed!

Great feel and support. Not too firm or too soft. Just right!!! Would recommend to EVERYONE! GREAT purchase!

Use it on any frame you want (even none!)
Directly on the floor

No furniture, no problem. You can put your Amerisleep mattress directly on the floor.

Box Spring

If you want to use your existing box spring, place a piece of 3/4” moisture resistant plywood directly on top.

Flat or slatted frame

A flat platform will work perfectly, so long as the gaps between the slats are no more than three inches apart.

Adjustable Base

Adding an adjustable base can elevate your comfort, allowing you to read or watch tv in bed.

What would you do with more energy
and less pain?

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?


Money well spent!

Best mattress ever!

I have bought other memory foam mattresses before. This one is better than any I've ever had! I can't explain why. I just know I wake up in the morning after a great night sleep. I didn't toss and turn. I didn't wake up every hour and look at the clock. I didn't wake up with sore joints or muscles. I just slept. And it feels great!

We use more eco-friendly memory foams.
Yet another way we’re better.

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.


Zero emissions


Fast, Easy & Free Shipping

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!


excellent bed!

Perfect bed for that semi-firm feel.

Great mattress, AS3 worked better for us


I really liked this mattress. Clearly quality construction and I love that I can get in bed (I work late) when my wife is sleeping and she doesn't even know I snuck in bed. If she tosses and turns, I am completely oblivious because there is no movement transmission with these mattresses. The AS2 is firm, offers lots of support and is great for back and side sleeping. I liked it but my wife wanted to go with something a bit softer. In the end, we ended up going with the AS3 which is perfect for both me and my wife's liking. I would be happy with either mattress long term, now we have had the AS3 for about 6 weeks I really like this mattress also.

I expected it to be a little softer. It is comfortably firm. I love it.

Lives up to its name


After only owning my previous Sealy mattress for 5 years my husband and I were both rolling into the middle of our saggy mattress. We knew we needed more support but had a hard time committing to a more expensive foam mattress. The Amerisleep mattress had a good reputation from a couple of family members and even though I'm a combination sleeper we decided to order the A2. I couldn't believe a King mattress could come out of that box but to my amazement it was a breeze. It took a couple of nights to get used to the support it provides but now I don't know how I could return to another mattress. As someone with minor back issues I really appreciate the support yet it is still soft and comfortable. We then realized we needed more supportive pillows since we had sunk so far into our previous mattress that they began to feel Iike pancake pillows now that we were elevated higher on the mattress due to the support. It's been about 3 months since we've received the bed and I haven't even wondered where we fall in the 100 day guarantee - it's staying!



Exchanged the AS2 for the AS3. AS2 was too firm for us.


After reading an article about "what mattress are best for back pain", we ordered the AS2 King thinking it would be the best model for my husbands back pain. The mattress was too firm to the point that his back pain got worse. I am a side sleeper and my side started getting sore. After calling Amerisleep and speaking with Anastasia, she recommended we try the AS3 King. My husband and I both are impressed with the AS3 and sleep sound through the night. So far it seems to be a great fit for us. We have No complaints with the AS3.


My Back Loves This Bed


Prior to using this bed, I was having chronic lower back pain and issues that refused to heal. I knew my old spring mattress was past it's prime so I decided I needed a new bed. I bought my Amerisleep mattress after reading online reviews that it was supposed to a good mattress for people who needed good lower back support. After the first few nights sleeping on this mattress my back pain subsided and I started to feel young again. I was a little concerned because although my back clearly loved the bed, it felt a little hard for my preference. I decided to give it more time since there's the 100 day money back guarantee and I still had plenty of time left. By the time another week went by my body had adjusted and the bed had the chance to break in a little. I've had the bed now for a couple months and I'm extremely happy. I no longer have to worry about back issues constantly and I have a great bed that I feel confident will last me a long time. It is definitely comparable to other mattresses that cost over double what this one does.

The AS2 mattress we purchased from Amerisleep is fantastic!


Love the convince of the item being shipping in a box. So easy to get the the room we wanted it in. My husband has a bad back and within a week his back was relieved of pain. He had complained for years about his back. Very comfortable- hoping it lasts for a long time! I have already recommended to two friends!

Cape Cod, MA


Bed is amazing !


We tried other beds, including other "box" beds. After the last one wasn't up to par, we spent several weeks researching the web and came across this bed. Thankful there was plenty of reviews to pick through. We decided on the AS2, I have lower back pain. The first night I slept for 9 hours straight. Since then, being honest, not every night is a 8-9 hour night, but I can say I am usually getting 6-8 hours a night now and I don't wake up with any joint pain. I will also so the AS2 feels very sturdy and I feel very supported when sleeping on it, also very little partner movement. We love it !
