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. 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.

 

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

My husband and I love Amerisleep!

5

My husband and I ordered the AS4 after reading great reviews for side sleepers. We went for the AS4 since my husband loves softer beds since he is broad shoulder. We got the bed and I was experiencing lower back pain since it was too soft for me. However, it felt awesome for my sciatica! I contacted Amerisleep and they sent the AS3 and picked up the AS4. The AS3 is perfect! The customer service and ease of purchasing the perfect mattress online was amazing and easy! Thank you.

I have never been so excited to turn in early!

i was skeptical of "foam" matresses but I have been converted by Amerisleep. The matress is much firmer than i expected. I am happy with this as the bed is solid. I love how silent the matress is compared to my old spring matress. The matress arrived in great condition and was fairly easy to put on my frame (the weight is substantial as it comes rolled up and is not stiff which is different than tossing a spring mattress on a frame. Overall I am very impressed with my matress during my first 90 days. I dont anticipate being dissapointed as time passes, but Amerisleep offers an outstanding 20 year warranty. i have reccomended this matress to a few co-workers and friends.

Most Comfortable Mattress Ever!

5

I bought this mattress to replace an older mattress that was no longer supporting my back. I have multiple spine problems that cause severe back pain. After reading the reviews for this mattress, I decided to give it a try, especially because of the 100 day trial period. I am very satisfied with this mattress. Although I do still have back issues that only surgery will help, this mattress has reduced the pain I have when rising in the morning. It so soft, yet supportive. I would recommend people to try this mattress. Everyone has different back issues. The mattress might be the cure for yours!

Best Sleep Ever! (Medium Soft Mattress)

5

This is probably the best bed I have ever slept on/laid on in my life. I kid you not. I used to have a Tempurpedic mattress and thought that was comfy but the Amerisleep mattress is amazing. I like to sleep on a soft-ish, firm-ish mattress so I ordered the medium soft. I did not sink all the way down to the floor nor was the mattress firmer than my Tempurpedic one. It was absolutely perfect. I am able to sleep through the night without waking up. I have lower back pain sometimes. When I sleep on this mattress when I have lower back pain, it relieves the pressure on my lower back by distributing equal amounts of pressure from my whole body onto the bed, which relieves my pain. I hope that makes sense. I like to sleep on my right side a lot, on my stomach and on my back and this mattress accommodates all of my sleeping positions. When I have children, I will buy them an Amerisleep mattress too. I don't think I would choose any other brand. Once you go Amerisleep, you never go back...and why would you?

Overall very pleased

In the beginning I thought the mattres was too hard. I typically don't like squishy mattresses that do not support, but felt like this mattress was not providing enough "give" to those hips and shoulders. As a side sleeper, firmer mattresses can be uncomfortable! I have since changed my review and think that this mattress has the perfect balance of support vs. cushiony comfort. Would highly recommend. My husband, a back sleeper who prefers firmer mattresses is also very happy with our purchase.

The softest mattress was a little too soft for my liking, but over all a good mattress. It was exactly as it was described. I would get one that is firm next time.

I love the mattress and sleep very well. The only con would be the Amerisleep company did not offer a base for sale at the time of purchase.

Great mattress!

I was having hip and shoulder pain when sleeping on my innerspring mattress. Online research revealed that AmeriSleep was the top rated mattress of both innerspring and foam. I was a bit hesitant because I was not able to try it out in a showroom, but decided to trust the online rating. So glad I did...love it. So comfortable...hip and shoulder pain gone!
