Have you ever heard of Infrared light and that it can improve circulation? Well, Amerisleep uses Celliant that turns your own body heat into energy. What will that do for you? Find out in our unbiased Amerisleep mattress review. Let’s see how the Amerisleep AS5 measures up and if it is the right mattress for you!

One of the unique features about Amerisleep that stood out to us was the Celliant used in the cover. Celliant is a mix of 13 thermo-reactive minerals that is woven in the top cover. When you lay on this your own body heat and natural infrared energy will be absorbed and then reflected back into your body even through layers of fabric. The result is more oxygen and better blood circulation making recovery time better after workouts and long days. So instead of going to a spa and paying a few hundred dollars for infrared light therapy, save time and sleep on your Amerisleep mattress. This makes Amerisleep a great recovery mattress for athletes and active people.

Shop Direct

Amerisleep offers amazingly high quality foam for a great price. They are able to do this by shipping direct to you instead of having brick and mortar stores throughout the nation. You might be thinking that you might want to try before you buy? I can tell you from experience, even if you could lay on it in a store you need at least 2 weeks to a month to know if a mattress is truly right for you. It takes time for your body to adjust to something new especially when it’s something you use for a third of your life. Instead of trying it in the store Amerisleep offers a long sleep trial and free shipping so that you can try it in your home, risk free.

Amerisleep Mattress Construction

Amerisleep has 5 different firmness options and all 5 have the follow features:

  • Celliant Cover: Celliant works with your own body heat and infrared to reflect it back on your body to absorb. This aids in faster recovery time and cooler sleep.
  • Greenguard Fire Sock: The law requires some kind of fire resistance in your mattress and often times its chemicals. Amerisleep fire sock has been Greenguard certified to show that their sock is safe even for your baby to sleep on.
  • Bio-Pur Comfort Layer: Open cell breathable foam that keeps you cool at night
  • Bio-Core Support Layer: “Won’t Sag Foam” plant based foam

Depending on your sleep style, Amerisleep has a variety of firmness levels to accommodate your needs.

AS1 - Firm

The firmest mattress in the Amerisleep lineup is the AS1. This will be a great choice for stomach sleepers and back sleepers who prefer a firm mattress. We would not recommend this for side sleepers or combo sleepers. The 10” mattress has 2” of Bio-Pur comfort layer and 8” of Bio-Core Support.

AS2 - Medium Firm

The AS2 is more firm – medium firm feel and will be best for stomach or back sleepers. The AS2 has an additional layer than the AS1. That layer is the 3” Affinity Layer with Surface Modification Technology (SMT), which is basically their fancy way of saying it is zoned. There will be different foam in your shoulders and lower back to provide more support where you need it. The 12” AS2 has 2” of Bio-Pur comfort layer, 3” Affinity SMT and 7” Bio-Core Support.

AS3 - Medium

Right in the middle the AS3 is a medium firm mattress. Depending on your mattress firmness preference this could be a good mattress for all types of sleepers. The AS3 is 12” and has 3” Bio-Pur comfort, 2” Affinity SMT and 7” Bio-Core Support.

AS4 - Medium Soft

Since the AS4 is a medium-soft feel this would be a better mattress for side and combo sleepers. Those that sleep on their back or side might prefer something firmer. The AS4 is 12” with 4” Bio-Pur comfort, 1” Affinity SMT and 7” Bio-Core support.

AS5 - Soft

The mattress we are reviewing is the AS5 and it comes in at a whopping 14” making it the most plush mattress Amerisleep offers. Like the AS4 this is a great choice for side sleepers and combo sleepers.

  • 3” Bio-Pur Comfort foam: This layer is a slow response memory foam
  • 2” Active flex foam: This layer is very responsive, so you won’t get that stuck in the mud feel
  • 2” Affinity SMT foam
  • 7” Bio-Core Support foam

Machine Washable

Having the ability to machine wash your mattress cover is fairly uncommon, so when we learned that Amerisleep’s mattress cover was designed to be machine washable we were pretty ecstatic. Most bed-in-a-box brands require spot cleaning of stains and dirt, so Amerisleep really stood out for this feature!

Firmness and Feel

It is important to note that firmness is subjective and things like height, weight and sleep position all affect how one will percieve firmness. We placed the AS5 at a 5.5-6 on the firmness scale. You still feel very supported when you lay on this mattress and don’t sink in far, in large part due to the responsiveness of the foams. It is almost as if you are sleeping on top of the mattress rather than in it. It took a while to get used to it as I am used to a really soft mattress and had to give it a few weeks to break in and really feel its full potential.

At first I felt that the mattress was too firm for my taste. I am a light weight side sleeper and typically prefer very soft. Although, I have felt overtime if I sleep on a mattress that is too soft it tends to lose the support needed for proper spinal alignment. After the inital adjustment period I felt Amerisleep did an amazing job of having just the right amount of softness without losing the support needed.

We also felt this mattress performed particularly well with heavy weight, side and combo sleepers. Often times soft mattresses just don’t support the weight, however, Amerisleep performed exceptionally in this area.

Is Amerisleep Good for couples?

A mattress that performs well in motion transfer is great for couples and those who sleep with children sneaking in their bed. Oh and don’t forget the furry friends that have dreams of chasing after squirrels. Jokes aside, we felt very little to no motion transfer on the AS5.

Edge Support

The edge support was ok on the Amerisleep. Typically all foam mattresses don’t do well in this category, however Amerisleep felt better than most. I think because of the 14” thickness of the bed helped. We didn’t feel as if we were going to roll off the bed although there was a bit of compression when we sat on the edge of the bed.

Does Amerisleep sleep Cool?

Nobody wants to sweat when your sleeping and that can be a real issue for some of us more than others. The Amerisleep AS5 slept very cool, in fact, more cool than most foam mattresses. My initial thoughts after reading about the infrared was I wasn’t sure how cool it would be, however, it was truly amazing, not one drop of sweat. The Celliant coupled with the open cell Bio-Pur foam really worked.

Is Amerisleep Eco-Friendly?

Eco-Friendly is becoming a household name lately. We are all trying to do our part to help preserve this beautiful planet. One way is to buy from companies that produce eco-friendly items, Amerisleep is one of them. All of the Amerisleep mattresses are made with foam that is manufactured with zero emissions. How they do this is through a process called Variable Pressure Foaming (VPF). They manufacture the foam in a completely closed chamber which ensures no emissions floating into the air. Furthermore, instead of using petroleum in their foam it is plant-based making this mattress a great eco-friendly choice.

Is the Amerisleep AS5 Mattress Right for you?

PROS- We really loved many things about the Amerisleep mattress. We can’t get over the many benefits the celliant cover provides, including increased blood flow and oxygenation, making it a great choice for athletes and active individuals in search of a performance recovery mattress. It is also one of our top picks for side sleepers, due to the balance between support and pressure-relief.

Not a side sleeper? Don’t fret, Amerisleep is available in 5 different firmness options, and could be a great fit for back, stomach and combo sleepers as well.

Lastly, if you struggle with sleeping hot we highly recommend Amerisleep. It’s literally one of the coolest mattresses we’ve reviewed so far.

CONS- Amerisleep is a bit on the pricey side, if you are looking to keep the costs down we suggest checking out of top picks under $1,000.

Amerisleep is a memory foam mattress, if you prefer the feel of a traditional innerspring mattress we suggest checking out favorite, WinkBeds.
