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.

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.

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.

 

Super Comfy!

I'm getting the best sleep ever! My Fitbit tracker shows my awake and restless times were cut in half.

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?

very comfortable

This mattress is used on our spilt-king adjustable frame and it feels very good.Most of the time when I go to bed at night I watch TV for an hour but I fall asleep with in ten minutes. The mattress is not too firm but just right and I get a good night sleep. I looked at many mattress and and I glad I choose the colonial mattress from amerisleep.

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!

 

This is an incredibly comfortable mattress. Worth every dime

Except for my occasional bouts of insomnia I'm enjoying the best sleep of my life due vastly to this mattress

Amazing

After reading reviews day in and day out, nothing is good but everything is the best. So Typical of anything you review before you buy. I Trusted my gut and went with Amerisleep. Made right here in the good ole USA. Then you look at the warranty, they really stand behind their product. This mattress is like sleeping on a cloud. So comfortable. This is coming from a person who spent Thousands on a Tempur-pedic just 2 years ago and needed to find a better mattress.

Great Bed

5

Great Mattress. Sleeps cool and has level of firmness as described. I tend to prefer a firmer bed (back issues) and my wife prefers very soft beds. The AS4 is perfect for both of us. Soft while giving good support. I am surprised some folks have rated it as "way too firm." My wife loves a super soft bed and absolutely loves it. Would 100% buy again.

Happiness Here

I am very satisfied with this mattress. As with any new mattress, you have to sleep on it for a few weeks before you know that you've met your match and this was mine. I was so happy to send my Purple bed back and luxuriate on the Amerisleep AS4. I am both a side and back sleeper and find the mattress gives just enough, I don't have that sinking feeling of a too soft memory foam. The value and customer service are excellent and would most definitely recommend Amerisleep. P.S. I also shopped at Sleep Number ($3 - 5K) and a national mattress chain ($3 -4K) and wasn't all that impressed by what they had to offer or the outrageous prices.

This mattress has truly changed my life. Years on end I've been waking up multiple times during the night due to either heat or the stiffness/cratering of my generic mattress. Amerisleep mattress has me sleeping through the entire night both cool and comfortably, I truly feel like I am sleeping on a cloud. Thank you Amerisleep for such an amazing product! I highly recommend this product to anyone in need of a new mattress or that is currently experiencing sleep issues.

I used to have a TempurPedic. It was a great bed, but it was time to replace. My boyfriend ordered an AmeriSleep. It was amazing - soy rather than petroleum products, no off-gassing noticed, as comfortable as my old mattress when it was new.
