Amerisleep AS5 Mattress Review

The Amerisleep AS5 is one of the five memory foam mattresses in the collection of memory foam mattresses by Amerisleep. This model is the softest of all five models, but it still has responsive properties so you don’t sink into the bed and get stuck. This bed is a good match for side sleepers looking for a comfortable, contouring bed that balances with enough support to maintain proper spine alignment.

Keep reading our in-depth Amerisleep AS5 mattress review to learn more about how this mattress performs and can bring you a better night’s sleep.

Amerisleep AS5 Mattress Highlights

• The AS5 is Amerisleep’s softest mattress model and is ideal for side sleepers and combination sleepers.
• Its foam comfort layers create a soft but responsive feel that relieves pressure points and makes you feel like you’re floating.
• In addition, the cover contains Celliant, which is known to reduce pain, regulate body temperature, and promote healthy blood circulation.

AS5 Mattress Review

The Amerisleep AS5 is the softest of their memory foam mattresses. It’s built with multiple layers of plush, absorbing foam that’s more than 12″ deep! These foams include Amerisleep’s proprietary, cooling Bio-Pur®, Active Flex, and HIVE® comfort layers. Combined together, these foams create a mattress that is plush yet responsive.

Some people prefer a more firm bed. Others (like most of us out there) prefer for their bed to feel like a comfortable cloud that you can peacefully drift off to sleep on. That’s what you’ll get with the AS5.

What does all this mean? 

It means that when you’re sleeping on the AS5, not only are you ultra-comfortable from the soft surface, but you also are getting the pressure relieving support you need to avoid pain in the hips, shoulders, and knees. This bed can make you feel like you’re floating!

Top that all off with the high-performance Celliant® cover and you’re practically guaranteed a good night’s sleep. This thermoreactive cover is designed to turn your body heat into infrared energy, meaning you’ll sleep cool all night long.

Customers Reviews of the AS5

“I have purchased the most expensive beds on the market and I would choose this over any of them that I have owned.” – Leigh

“I compared every mattress made for over TWO weeks. I just wanted to get this right. It is everything i hoped it would be. I was really hesitant about the AS5 being too soft but it is not. It is perfect. I have a really bad back. My wife is a full time back sleeper. We are both thrilled to death. We have been sleeping on this bed now for 5 weeks. It is unreal. I have also slept on a purple and it does not compare to this AS5. WOW, WOW, WOW.” – Marty

“We have two twin XL mattresses in a king frame. They are amazingly comfortable, and allow for each of us to move independently without waking the other person up. We are very happy with our new purchase. It is great in terms of temperature and responsiveness. No smell, and easy to set up as well. The best part of all of this, is that they have the top customer service in the industry. I accidentally ordered the wrong size and they straightened it out and issued a refund, donating the wrong mattress as well. And they did this all pleasantly and quickly. Absolutely amazed. We will never buy from anyone else again. Great experience.” – Teri
