Amerisleep AS2 Mattress Review Highlights

The Amerisleep AS2 mattress is a memory foam mattress from Amerisleep’s series of mattresses. AS2 is their firmer model, and in this review, we’ll break down what you need to know about this mattress. That includes sizes, prices, pros, cons, how it scored in our lab evaluations, and more.

To learn all about the AS2 and see if it’s the best mattress for you, keep reading.

What we love about the AS2:

  • The Amerisleep AS2 model is a top mattress for back sleepers and one of the best mattresses for stomach sleepers – it has thicker foam than the AS1 model and contains a transition layer which gives it a little more cushion.
  • The AS2 also offers great cooling properties – the top layer is designed to help wick heat away from your body and the cover incorporates fiber with strong energy transfer capabilities, to give you a cool-to-the-touch feel.
  • Like all of Amerisleep’s other mattresses, the AS2 is made in the USA and comes with a 100-night risk-free sleep trial.

AS2 Performance Highlights

✅ Pros

  • Motion Transfer: People who sleep with their partners, children, or pets don’t want to be woken up by each other’s movements. The AS2 offers great motion isolation to keep away motion transfer that will rouse your partner.
  • Pressure Relief: The AS2 mattress gives superior pressure point relief in the body’s most sensitive areas that press into the mattress to most, like the hips, shoulders, and lower back.
  • Spine Alignment: While sleeping on your side, you want your spine to stay perfectly straight, and while sleeping on your back your spine should maintain its natural curve. The AS2 does just that.
  • Responsiveness: Combination sleepers and those who move around at night need a responsive mattress that can keep up. The AS2 received a nearly perfect 9.5 out of 10 in our responsiveness test.

❌ Cons

  • Off-Gassing: When you free the AS2 mattress from its box, you will likely encounter a slight off-gassing scent. This is normal when opening all-foam mattresses and should go away after airing out the mattress for a few hours.
  • Edge Support: AS2 may not be the best choice for people who sleep on the edge of the bed or spend a lot of time sitting there to get ready for the day since it performed poorly in this evaluation area during our testing.

Product Information

How Firm is the AS2 Mattress?

AS2 is a firm mattress, falling at an 7/10 on the firmness scale. Back and stomach sleepers benefit most from a firm bed. If you prefer a softer mattress, consider one of Amerisleep’s softer mattresses, like the AS5 and AS4.

What Sleeping Position Does the AS2 Mattress Support?

The AS2 is a great choice for all sleeping positions. Firmness-wise, it’s best for stomach sleepers and back sleepers. When it comes to pressure relief and alignment, it wins as a great side sleeper mattress. The AS2’s responsiveness also makes it a good mattress for combination sleepers.

Does the AS2 Mattress Sleep Hot?

Memory foam mattresses are known to trap heat and sleep hot, but the AS2 mattress uses open-cell breathable foam paired with a Refresh Cooling Cover that changes your body heat into infrared for a cool-to-the-touch feel.

Even with these cooling layers, AS2 still won’t be as cool as a latex mattress or an innerspring bed.

How Much Weight Does the AS2 Mattress Support?

The Amerisleep AS2 can hold up to 400 lbs on twin-full size beds and 800 lbs for queen size and above. This means that AS2 supports most body types and sizes.

What Foundations of Bed Frames Can be Used with AS2?

Amerisleep recommends putting your AS2 on a flat surface. This includes a slatted platform frame, box spring, adjustable base, or even the floor.

What is the AS2 Mattress Made of?

The AS2 mattress is a memory foam bed made using CertiPUR-US certified foam layers.

  1. Refresh Cooling Cover: Designed to keep you from overheating by converting your body heat into infrared for a cool-to-the-touch feel.
  2. Bio-Pur foam: Contouring, breathable, cooling comfort layer with an open-cell structure.
  3. Affinity layer: A layer of transition foam; the ergonomic design provides pressure relief.
  4. Bio-Core foam support layer: A base layer made of high-density and eco-friendly support and durability.

AS2 Mattress Unboxing

The mattress comes compressed in a conveniently sized box, so you can easily take it to your room. It took us less than two minutes to unbox AS2. It even comes with side handles to make the setup process easier.

AS2 does have an off-gassing smell, so we recommend airing out your new mattress before dressing it up with sheets and bedding.

Customer Reviews

  • “There are not enough stars to give this mattress – I could give it easily 10stars rating. We call it ‘our cloud’ as this is what I could imagine feeling sleeping on a cloud (if it was possible). I had lots of problems with my back (burst disc, bulging discs) and wasn’t happy with my old mattress – I paid 750 for it and it was never really good. After the first night on my new Amerisleep mattress, I cannot recommend it highly enough. No pain in the morning in my low back, no stiffness. I’m just one happy client. Hopefully it will last for many years.” – W.L.
  • “This mattress has immensely relieved my back pain. It is just the perfect balance with firm support and a soft feel. I could stay in bed all day without the pain that I was feeling from my old, much softer, mattress.” – Jenny
  • Incredibly comfortable and supportive. My husband and I woke up with zero aches and pains the very first morning we used it and we knew we could never go back to a spring mattress. I was worried about it holding in warmth since we are both hot sleepers but we have had no problems with that at all. It’s comfortable sleeping on my back, my side, and even my stomach. It literally cradles every part of you. I would buy this again in a heartbeat. I have nothing bad to say, even customer service and shipping was great.” – Autumn
