Customer Reviews of the AS3

Amerisleep AS3 mattress reviews from customers with back and joint pain:

  • “After 12 years on our old mattress, we splurged in Amerisleep and am so glad we did. Back and neck pain gone!” —Sam
  • “I’m usually a budget shopper but there are some things you can’t skimp on. I have had neck back and shoulder problems for years. I knew I needed a good mattress. I read so many reviews of this mattress/company and people saying they had less pain. I 100% agree! I feel so much better when I wake up. Makes getting out of bed harder for my husband he’s been sleeping longer!” —Marileezy
  • “A very supportive mattress for my severe back problems; I now get a most restful sleep and a longer one” —Ika

Amerisleep AS3 mattress reviews on comfort:

  • “We were in the market to buy a new mattress and read excellent reviews for the AS3. It was comparable in price versus other foam options. We were pleasantly surprised to realize that the great reviews were true! We’re big fans of this mattress because of its comfort while also being cool to the touch.” – The Stins
  • “The AS3 is spectacular. We came from a 10 year old mattress and it was time to upgrade. We looked at a ton of mattresses in the stores. Some were great and incredibly expensive, others were just ok and cheap. After doing some research, we found Amerisleep. Honestly, we were very skeptical about purchasing a mattress online but with their warranty/return policy, it wasn’t an issue. After receiving the mattress (great packing, by the way) and sleeping on it for a couple of months now, we couldn’t be more happy with it. It blows away any other mattress we tried in the stores.” – Chad

Amerisleep AS3 mattress reviews on sleep quality:

  • “Great bed I use personally. I’m a very light sleeper and this thing keeps me sleeping all night!” – T. Knox
  • “This bed is amazing! I went from a Serta memory foam mattress to this bed and I can’t believe that I waited so long to make the switch. It’s comfortable and I sleep way better on this mattress. It will change your life. The only problem (its minor-most nights I don’t even notice)Is that it stays a little warm. Love the product and it’s worth every penny.” – Ben
  • “Never bought a mattress in a box, but very glad we did. Have been sleeping on it for about 4 weeks and have nothing but good things to say about this product. Great support,value and overall comfort. Getting a good night sleep finally.” – AJ
