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.

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!

    Comments about Firm Memory Foam Twin Mattress by Amerisleep - AS1 10" x 38" x 74":

    This has been buy far one of the best purchases I've ever made. My fiance and I went through 3 different mattresses before we hit the jackpot with this one. We both suffer from back pain and could not find a firm mattress that was actually comfortable...until this one! We could not be happier. And the price is the best part! We tried some of the higher end foam mattresses and felt this one was far superior in terms of quality and comfort. Have already recommended several friends and family members. 5/5 stars, no hesitation

              I used to sleep on a very firm Tempurpedic mattress, which I loved. When it came time to replace it, I bought the firmest mattress Tempurpedic now makes, but it was totally different--and way too "squishy." So I researched other options, and came across Amerisleep's offering. Based on the reviews, it seemed that this was the mattress I wanted. And at a much better price-point than Tempurpedic! It did not disappoint. Firm, with no "bounce." I hate bounce. But it cradles your pressure points so it's never "hard." It's so comfortable that I bought another one for my weekend home. Now I sleep on an Amerisleep mattress wherever I rest my head!

              Service and delivery comments:

              Delivery was quick--even faster than the original estimate. The package takes a bit of time to unwrap, but once you set the mattress free from its shrink-wrapped package, it expands quickly and is ready to sleep on almost immediately.
