  • 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.

Customer Reviews on the Amerisleep AS3 Mattress

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

Amerisleep AS3 FAQs

How does the 100-night trial work?

From the day your Amerisleep AS3 mattress is delivered, you will have 100 nights to decide if the mattress is right for you. If you decide to return your AS3, you’ll simply contact the customer support team within your trial period window and they will walk you through the return process. A representative will arrange for your mattress to be picked up from your home and donated to a local charity in need. You won’t need to put the mattress back in the box it came in.

How long will it take for my AS3 mattress to ship?

The Amerisleep AS3 Ships free to the lower 48 states and usually arrives within 5-10 business days.

Is the AS3 mattress eco-friendly?

All the foams in the AS3 mattresses are CertiPUR-US® certified, meaning they meet some of the most rigorous standards for emissions, content, performance, and durability.

Will the AS3 mattress have a break-in period?

It does – in fact, all mattresses do! It can take up to 30 days to fully break in your new mattress. During this time, your body will get used to the new mattress feel and the mattress will have time to fully take shape and provide all the benefits it was designed to offer. But the good news is you have plenty more than 30 days in your trial period!

Amerisleep offers 5 different foam mattress models in varying levels of firmness:

  • AS2: Medium-firm; popular among stomach and back sleepers
  • AS3: Medium; best-selling model, most versatile
  • AS4: Medium-soft; popular among side sleepers
  • AS5: Softest of the 5

Will I need to flip my Amerisleep mattress?

You won’t, and you shouldn’t! The Amerisleep AS3 is meant to be used on one side only.

  • Amerisleep sells an adjustable bed base ($1,900 for queen) as well as sheets, pillows and mattress protectors.
