No mattress is more carefully engineered.
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.

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.

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?

Best mattress ever!

This is the second Amerisleep mattress we've bought. The first is in our master bedroom and we've been sleeping on it for 2 years and it is just as perfect as the day we bought it. The new mattress is for our guest bed. We also have an Amerisleep foam pad for our couch bed. And Amerisleep pillows; ah the pillows! No more neck or back aches. Just a great comfortable pain-free nights sleep.

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 Product!


Excellent product and just what I wanted.

Minneapolis, MN




My husband and I are in love with this bed! We have had it for several weeks and have zero complaints. Both of us have back issues and prefer a really firm mattress. I doubted a bed in a box would be firm enough, but it is perfect. My back pain has definitely improved since we bought this. We love it and would highly recommend!

Portland, ME


Best bed ever!


Bed is firm but comfortable; purchased it after reading the reviews. Was torn between the firm and medium firm. More reviews leaned towards medium firm but I have a bad lower back and need a firm. With Amerisleep's guarantee... We were sold on "trying" it and knew we could switch to medium firm if we weren't happy. After a month and a half, happy is an understatement. We love our bed!

Orlando, FL


Quality bed


Needed a new bed after moving. Was looking around and tried a different online based bed in a box company, but that bed was way too soft. It felt like I was sinking into the bed and could practically feel the slats underneath. Returned that bed and was looking online and found amerisleep. Got the amerisleep AS1 because I like a firmer bed and being the firmest in the lineup I chose it and the risk free returns helped me choose a mattress from amerisleep. Love the mattress. Love the firmness and would recommend the company to friends.

I would buy this product again!!!


We love our Amerisleep bed! We used to go to stay at a motel because the beds were better but not anymore! Our new Amerisleep bed is so amazing we drive more to get home to our bed!

Incredibly disappointing. Worst mattress I've ever had.


I tried 2 types of mattresses from this company.I am a side sleeper and have always slept on spring mattresses. I had been sleeping on a sofabed for many years and needed a real mattress to sleep on. First, I tried the one they recommended for side sleepers. I found it to be much too soft and then tried the AS1 which was recommended thereafter. I am tiny- 5'4 and 104 pounds. This mattress caved in the middle after SIX DAYS of sleeping on it. That should not happen. I called to let them know this was happening and that I felt it was sinking in not only where I was laying, but moreso under my hips/butt area, thereby forcing my hips to sink down and my back to be misaligned. The first person I spoke to told me to wait a few more months, that i was just not used to it. I did, and it got worse. I called again and they told me it was a defect and shipped out another one. Same exact thing happened with the next one. The mattress is terrible- too firm where my shoulders hit the mattress and weak/sunken under my hips/butt area. I have developed incredible TMJ on this mattress along with additional back problems. When I called about this, they told me to try sleeping in every possible position on the bed to try and "even out the dents." This is an unreasonable and ridiculous request- I paid a lot of money for this mattress and should not have to "run around the sides" of the mattress and sleep in every possible position all over it for it to be comfortbale. i was desperate, so i tried. It did nothing except get lumpier. i asked if there was anything they could do and they said no, I was outside the 100 night window. Interesting because the first rep I spoke to gave me MISINFORMATION when she told me to "stick it out for a few more months." Just long enough so I wouldn't be covered by the warranty? Hmm. THIS COMPANY DOES NOT CARE ABOUT IT'S CUSTOMERS! Their mattresses are terrible. I am so upset to be stuck with this mattress. BEWARE Amerisleep.

New York, NY


Great bed.


It smelled a little plasticky when I opened the box but that went away pretty quick. I slept on a futon waiting for this bed to show up and the difference is incredible. I got the A1 looking for support and it's worked out great. I overheat easily but this bed has not caused my any issues with sweating or anything like that.

DeKalb, illinois




My husband requires a firm mattress; otherwise, he wakes up with terrible back pain. Although I prefer firm mattresses, I though that the AS1 would be too firm for me and uncomfortable. I was wrong. It is extremely comfortable and I'm not as achy as I was before. I guess I didn't realize it was the mattress and assumed it was just part of getting older. So glad I found the perfect mattress for both me and my husband.

Vienna, VA


Very nice. Comfortable.


Very nice.



Fantastic Bed


Very happy with this purchase. We've purchased a lot of expensive beds (like $2,000+) and they are terrible. This bed is amazing, firm, comfortable - perfect for my husband and I. Thanks.
