The AS4 delivers exceptional comfort with our latest innovations. Our new technologies Bio-Pur+™ and Surface Modification Technology will help you sleep cooler and feel targeted pressure relief.
The firmness of a mattress is determined by how it initially feels when you lay down.
Note: Firmness does not directly relate to the amount of pressure relief and support that a mattress provides.
We're here to make sleeping easy and hassle free. When you order your mattress we'll ship it to you for free. Not in love with how you're sleeping? There's no need to ship your mattress back. Call us and we'll handle the mattress pick up and refund you in full.
Foundations, adjustable beds, mattress toppers, pillows, protectors, sofa beds, or any other accessories are not available for return.
My husband and I have both noticed a reduction in back pain and better overall sleep.

Our innovative and proprietary materials let us build one of most comfortable mattresses ever
Celliant® is an advanced fabric made with 13 thermoreactive minerals that helps improve the performance of the mattress.
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.
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.
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.
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.
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.
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'm getting the best sleep ever! My Fitbit tracker shows my awake and restless times were cut in half.
I sleep on this bed every night and it is very comfortable. plus..it is made in America! Would order more products from Amerisleep and highly recommend to others.

No furniture, no problem. You can put your Amerisleep mattress directly on the floor.
If you want to use your existing box spring, place a piece of 3/4” moisture resistant plywood directly on top.
A flat platform will work perfectly, so long as the gaps between the slats are no more than three inches apart.
Adding an adjustable base can elevate your comfort, allowing you to read or watch tv in bed.
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?
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.

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.

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!

We've slept on this bed for 9 months now. It's the perfect blend of softness and support. It's so comfortable we have accidentally slept till noon on many occasion! My husband has had knee and shoulder surgery and this bed is comfortable for him to sleep on his side. My back and hip pain from standing at work all day is decreased. My kids are always trying to sneak in to sleep on it. This is the best bed we've ever owned.

My mom slept on the bed and said she had the best sleep ever. The bed is 2 years old. The mattress squeaks a bit but not to noisy.

The Amerisleep was a great option for us based on the multiple bed choices and the environmentally friendly nature of the product.

I love this mattress. I normally like very soft mattresses and I was afraid that this one would be too soft, but it definitely is not. It's soft in all the right places but stays firm and supportive.
Sleeps a lot

I sleep better, mostly uninterrupted compared to before, change my pillow as well since the mattress does part of the job for head support.

Get the as4! My wife and I are both under 160 lbs and this bed has been awesome! As3 felt stiff for us but this bed has been great!

Sleep better without a doubt. Less neck and back pain. Got the medium-soft mattress and still seems a bit too stiff at times. Still a great purchase.

We have had our Amerisleep AS4 for about two months now. It is living up to the hype so far. My husband and I both have back problems and needed support plus give in the mattress. The Amerisleep AS4 fits our needs perfectly (for reference purposes, my husband and I are both under 160lbs). In fact, the first night we had our new Amerisleep, my husband slept for 10 hours straight! That has never happened in the 20+ years we've been married! I haven't been waking up in the middle of the night with pressure-point pain in my hips for the first time in a long time. It's been a smashing success so far. I have noticed that by morning, there is a slight dip in the mattress where we sleep, but at bedtime, the mattress is back to mostly original fill. If that changes and a permanent cavity develops, I'll update here. My hope is that I won't have to replace for several years. And when I do, it will be most likely be another Amerisleep.
