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 bed

Purchased for bed ridden mother with an electric hospital bed. Mattress bends well and comes back to original shape.

Mattress is causing back pain. Apparently, I may be sinking straight to hard layer.

Los Angeles, CA

By far the best mattress I ever had


So far no cons besides making it impossible to get out of bed in the morning...

Ithaca, NY


Great mattress.


This mattress is one of the best mattresses we have Purchased. Doesn't sink when you get into it. My wife always complained that the bed would sink in when I got into bed not anymore. No problems. Thanks





We have been trying this mattress for a few weeks now. It's sturdy and comfortable, a bit hard at first but we chose the firmest mattress (AS1). Once we got used to our new mattress (took 2-3 days), we are totally in love. It's the best use of our honeymoon money! We'll save up and have a real honeymoon in a few years. I would highly recommend Amerisleep to all my friends and family. It's also very convenient because it's shipped right to your doorstep. If you are on the fence, do it! We shopped around for and in store, and This is the best price for a high quality mattress.



AS1 Review


I was really hoping the AS1 would be the right fit. I am more of a back and side sleeper and after awhile my shoulder and hips started hurting. I like that you sleep on top of mattress and don't sink in. I like that it was firm and felt like it was a good quality mattress. I have exchanged to AS3, Amerisleep recommendation, so far my back has hurt with this one but maybe I need time to adjust b/c it's softer then the AS1. Not confident the AS3 will work for me either.



Average product - AS1 Mattress


I've been using the AS1 mattress for over two months. The mattress seems to be sturdy but has weaker edge support, vibration and less comfortable.




Perfect for my needs. Very comfy.

San Francisco, CA




This is my primary bed. I need a very firm mattress and this one is perfect! Absolutely love.

Wife's back aches disappeared!


We had a Sleep Number bed and originally thought that would provide comfort for both of us while being firm enough for her back needs. That turned out to be false after many years, no matter how firm the bladder was. We looked for another alternative and read about the Amerisleep brand of memory foam mattresses. Not only did we get a bigger mattress (king) for about half as much as we paid for the previous queen, it also came with their 100-day sleep guarantee! It only took less than two weeks for her back aches to fade away. I find it quite firm but sleep better than before. Other pluses: There isn't ANY noise and it holds its shape very well - I can't even tell when she gets into or out of bed. I wish we had bought this mattress years ago!

Smithfield, VA


Great mattress!!


My wife and I have back pain but have enjoyed sleeping with no pain!
