The Amerisleep AS2 and AS3 mattresses are both 12” memory foam mattresses made from the same 3 layers. Thanks to variations in the thickness of each layer, these beds are best for different sleepers.
Let’s take a look at what sets these mattresses apart.
The Amerisleep AS2 mattress is crafted from three layers of foam that contribute breathability, contouring, and support.
With a thin (2”) comfort layer, the AS2 doesn’t allow the body to sink in too low. Directly underneath the top layer of memory foam is a thicker (3”) polyfoam layer. Thanks to zoned support, this layer ensures that the spine stays supported and the hips and shoulders cushioned.
The base layer of the AS2 mattress is their sturdy Bio-Core polyfoam, whose high-density construction adds durability and prevents excess sinkage or sagging.
The Amerisleep AS3 mattress is made using the same 3 foam layers as the AS2 mattress, but thanks to variations in thickness, it boasts a softer, more conforming feel.
The upper layer of the AS3 mattress is a generous 3” of plush memory foam, which is 1” thicker than the AS2. This added thickness makes the AS3 feel much more like a traditional memory foam mattress that deeply cradles the body.
The transition foam is the same zoned foam as the AS2, just 1” thinner, and the support foam layer is identical.

Maintaining proper body alignment is just as important while sleeping as when you are awake. Because you aren’t able to control your posture when asleep, it’s up to choosing the right mattress to do it for you.
When we put these mattresses to the test, the Amerisleep AS2 scored slightly higher than the AS3 for spinal alignment. With an extra inch of zoned support foam, it makes sense that the AS2 would do a better job of keeping the body in a healthy alignment. If you struggle with aches and pains and enjoy a firmer mattress, the AS2 may help you find relief.
If you’re someone who sleeps along the edge of the bed, or if you use the edges to put your shoes on, the best mattress for you is one with solid edge support. Couples and those who share their bed with kids or pets tend to use the entire mattress surface, making edge support important.
The AS3 scored higher for edge support, earning an 8/10 (in comparison to the AS2’s 7.5/10). That, combined with impressive motion dampening abilities, makes the AS3 a great option for those who share the bed.
Memory foam mattresses have a tendency to make it harder to move around when compared to a hybrid or innerspring mattress. Some foams allow you to sink in too much, or they may simply change shape slowly. Both of these properties make it hard to get comfortable when you switch positions at night. Sleepers who toss and turn are best suited by a responsive mattress, which is one that readily adapts to your movements.
Fortunately, not all memory foam mattresses are hard to move around on. The Amerisleep AS2 scored an impressive 9.5/10 for responsiveness, in comparison to the AS3’s 7.5/10. Combination sleepers and anyone who moves around a lot at night are likely to prefer the ease-of-movement that the AS2 supports.
When looking at the performance of the AS2 vs AS3 mattresses during our in-house testing, the AS2 outperformed the AS3. Its impressive responsiveness and ability to balance lumbar support with pressure relief make it an excellent mattress for those who prefer a firmer memory foam feel.
However, there are those who prefer the AS3 to the AS2. With superior motion isolation and edge support, most couples are going to sleep more soundly on the AS3. Additionally, it’s softer and brings a more traditional memory foam feel, a combination that’s better for side sleepers.
No matter which bed you choose for your new mattress, it comes with a risk free 100-night sleep trial and generous 20-year warranty.
