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.

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

The Active Flex layer is our most responsive comfort foam — and it only comes in the AS5. Because it bounces back so fast, it lets us add even more softness and cushioning to the AS5, but without making you feel stuck as you move around at night.

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.


I love my new Independence bed

I get a good nights sleep every time I sleep on my Independence bed. Very comfortable and easy to set up.

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?

Great mattress fantastic company top customer service

We have two twin XL mattresses in a king frame. They are amazingly comfortable, and allow for each of us to move independently without waking the other person up. We are very happy with our new purchase. It is great in terms of temperature and responsiveness. No smell, and easy to set up as well. The best part of all of this, is that they have the top customer service in the industry. I accidentally ordered the wrong size and they straightened it out and issued a refund, donating the wrong mattress as well. And they did this all pleasantly and quickly. Absolutely amazed. We will never buy from anyone else again. Great experience.

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!


I would recommend this product

I have purchased the most expensive beds on the market and I would choose this over any of them that I have owned.

Great product




Fantastic mattress!


Great mattress- no more hurting shoulders. I used to toss and tumble all night trying to relieve pain in my shoulders, hips, back, etc and then get up with pain in my shoulders that would last all day- after just a couple of weeks on our new mattress...all of that is gone! We got the softest mattress and love it- it's very comfortable without sinking down into the bed.

Sleeping on a cloud!!


The bed is great!! Very soft with plenty of support. Perfect for side and stomach sleepers. Me and my girlfriend now use the bed more than the couch. Works well with an adjustable frame.

Atlanta GA


Definitely breaks in and gets a little softer


I got the AS5 and have decided to keep it, but would have been fine with the AS4 after break in. Either way it is very comfortable and has improved my sleep.

Northern California


Exceptional mattress!


Not sure what the others reviews are about as being to hard or soft. I am a side sleeper and have done thorough research on my options. This is exactly as described.



Not too soft!


I was on the fence with this one. My husband likes soft mattresses and I like medium to firm. I was very afraid this one would be too soft but after reading the reviews on the other mattresses, I feared those would be too firm for him. I made the right choice! This one is perfect for both of us.

Sleep On A Cloud


OMG this is the Best. Bed. Ever!! I have *never* slept on a more comfortable mattress, and lemme tell ya... at my age... I've slept on a lot of mattresses. This is the first memory foam type mattress I've ever owned but it's worth every single penny! It's made of awesome, layered with pillowy cloud-like substance, wrapped in a cooling fabric that must be brought from heaven because seriously, I feel like I'm in Mattress Heaven with this mattress! My aching lower back and arthritic left hip pain immediately diminished to almost nil the first night I slept on this mattress, plus my shoulder joint pain is completely gone. The mattress supports my heavy weight and lumbar region, without putting my joints into agony like traditional mattresses. I've tried memory foam toppers, and mattresses with memory foam tops already built in, but they are NOTHING like this mattress. I'll never go back to a traditional inner spring mattress again. I'm completely over the top happy with my purchase!! Best yet - the 100 Night Sleep Trial didn't start until the bed was fully setup and I know I won't need to return the mattress. It's too awesome to send it back! I love this mattress!!! Thank you, Amerisleep, a million times over!!

Jackson, MI


I would definitely buy this product again


Exceeded my expectations.

New york


Great purchase!


It took a couple of weeks to get used to it since it's so different from our old, lumpy bed. But, then started to love it! So comfy!

Rockville, MD


Great bed overall but wrong firmness


I would have given this bed five stars if it was a little more firm. I struggled between getting this mattress and the next one up that was a little more firm. When reading the reviews, it seemed that people thought even this mattress was too firm. As someone who deals with rheumatoid arthritis and has a lot of back pain and joint pain, I need something soft enough, but not too soft, which is why I originally chose this mattress. This bed is excellent overal, but is too soft and I will likely be returning it for one that is just a little more firm. I had been sleeping for years on a sleep number bed which could no longer provide the amount of joint support I needed. If you are a chronic pain sir, I highly recommend Amerisleep.
