The brand Amerisleep is known for their wide array of mattresses, as it seems they wanted to make a model to fit any sleeper position. AS1 is the firmest and most inexpensive mattress in the Amerisleep lineup. It isn’t quite as thick as the other beds, but that’s because it uses slightly less foam to achieve a firmer, more supportive feel. If you’re in the market for a firm, dense memory foam mattress (we’re talking to you back and stomach sleepers), keep reading on to hear our thoughts on the AS1 Amerisleep Mattress.
Amerisleep AS1 Mattress Firmness and Feel

Because there’s memory foam in the top layer of the AS1 mattress, it’s going to feel like a memory foam mattress. In general, memory foam is known for its conforming behavior. In other words, as you lay down on memory foam, you nestle into it, and the foam starts to contour to your body’s shape.
In Amerisleep’s case, we actually think the beds have what’s considered a dense memory foam feel, somewhat similar to the Nectar mattress. We also found it fairly easy to switch between positions on the Amerisleep beds. Sometimes with memory foam beds, sleepers will find it requires a little extra effort to switch positions. Luckily, that’s not the case here.
Firmness
Like we said earlier, this is the firmest mattress from the Amerisleep bunch. As you can tell from our graphic above, we rated it on the firmest end of our scale.
Pressure Relief
If you’re seeking pressure relief, you will not find it on the AS1 Amerisleep mattress. Instead, we suggest the AS3 model or anything higher. This bed’s bread and butter is support, and we don’t think it’ll be too great at relieving pressure points.
Temperature
The Bio-Pur memory foam the company uses isn’t from the 1980s. It has an open-cell structure, which makes it much more breathable than traditional memory foam. As a result, it’s more temperature regulating. It’s also more firm, so you sit on top of the bed rather than inside it.

Amerisleep AS1 Construction and Design
The AS1 mattress is the firmest mattress in the lineup, and as a result, is also the thinnest because it doesn’t contain as much foam as the others in the catalog. Here’s how the 10” AS1 layers stack up:
Bottom
This foam layer is 8” of Bio-Core foam, and its job is to support the rest of the mattress. It’s also eco-friendly, partially made with a plant-based material!
TopThe top layer is made with Bio-Pur Memory Foam. It’s found in every Amerisleep mattress, and it’s built to be more open-celled, so it doesn’t retain heat like a traditional memory foam mattress does.
Will Amerisleep Beds Work For Couples?
For people sleeping with a loved one, we recommend you consider a bed’s motion isolation and edge support. Lucky for you, we went ahead and tested that out for you too.
Motion Isolation
The water in the glass didn’t move around all that much despite the activity on the surface of the mattress during our motion isolation test. This means you likely won’t feel too much of your partner’s movements throughout the night.
Edge Support
In addition, the beds also provide fairly decent edge support. We really didn’t notice any major issues in this department during our tests. This is an important subject for people who share a full or queen size mattress. Solid edge support means both partners will be able to use the entire surface area of the mattress and still feel properly supported.

Amerisleep Pricing & Coupon Code
Amerisleep beds are priced near the middle-to-higher end of the online mattress space. The AS1 mattress is the cheapest model in the lineup (AS1) and has a queen size MSRP of around $1,200.
Speaking honestly, we think the pricing is a little high; however, to be fair, the numbers mentioned above are based on MSRP. Amerisleep does seem to be fairly aggressive when it comes to discounts and coupon codes. In most cases, you can expect to receive a $200-$250 discount on your purchase.

Amerisleep Review Verdict
If you’re in the market for a firm memory foam mattress that won’t retain heat like the older models from a decade ago, this is a good choice. It’s not as affordable as other dense memory foam beds we’ve tested, but it also comes with an extra perk like a machine washable cover. Though, people over 230 lbs will likely want a more supportive bed since this one is solely made out of foam.
