Founded in 2010, Amerisleep offers a small range of mattresses that are designed to be high-performance and supportive. The AS2 is the brand’s most powerful and also the cheapest option in the range. It’s available as either a full-foam or a hybrid. In this article, we’ll take a closer look at AS2, to see how it compares to the rest of the day The best mattresses.
We’ll explore factors like design, price, comfort, and support to help you decide if it’s a good fit Mattresses in a box for you. Since we haven’t had a chance to test this bed for ourselves yet, we also combed through existing customer reviews to get a picture of how the AS2 performs in practice. Let’s see if the Amerisleep AS2 mattress is the right choice for you.
Amerisleep AS2 Mattress: At a Glance
Specifically designed to promote healthy spinal alignment, the Amerisleep AS2 is marketed as a good mattress for back pain. It’s available in either all-foam or hybrid versions. Both feature the brand’s “Bio-Pur foam” instead of traditional memory foam; The full-foam version adds a custom layer designed to promote proper spinal alignment, while the hybrid has a layer of pocketed springs to increase responsiveness.

This is Amerisleep’s firmest mattress, with the brand rating it medium (there’s no rating out of 10, and no information on whether there’s a difference in firmness between the full-foam and hybrid versions, so we assume it’s the same for both). Typically, we recommend this level of firmness to stomach sleepers or sleepers, who need that extra support to keep their spine in this position. The firmer sleeping feel means the Amerisleep AS2 probably isn’t the best mattress for side sleepers of any shape or size, though, because there’s a risk of pressure points building up at the shoulders and hips. Current reviews reflect these sentiments.
Although not specifically cooling mattress, Amerisleep has set its mind to keeping sleepers cool at night. Our brand Bio-Pur foam features an open cell structure that should provide more breathability than traditional memory foam. There is also a cooling cover designed to draw heat away from the body. We expect the hybrid version to be more breathable of the two options, because the coil layer provides a place for air to circulate.
Customers also say that the layer of springs in the AS2 Hybrid also gives the mattress good edge support, and while motion transfer isn’t bad, those sharing a bed with a really restless partner might want to consider the all-foam version of the AS2 for greater motion isolation.
Prices for the AS2 start at $1,299 (MSRP) for a twin mattress (or $1,499 for a twin hybrid), but we often see generous discounts of around 30% on these mattresses, so don’t expect to pay full price.

Amerisleep AS2 mattress: design and materials
Starting at the top, the AS2 is covered in Amerisleep’s Cooling Hood, designed to help move heat away from the body. Beneath it is a layer of Bio-Pur foam, specially designed by Amerisleep to be cooler and more breathable than traditional memory foam, thanks to its open cell structure.
If you choose the all-foam version, the next layer is the HIVE transition layer. This is intended to give the head, back, and legs extra support, while also enhancing cushioning around the shoulders and hips. This sits on top of a chunky “Bio-Core” base, which is primarily found for durability and stability.
The design of the hybrid version is a bit more complicated. Underneath that top layer of Bio-Pur is a thin layer of firm foam to give the mattress stability. Below this is the main support section of the mattress – an 8-inch layer of coils, which makes for a more responsive sleeping surface. The files on the left and right sides are stiffer, to support the edge support, although this does not extend to the head and foot edges.
All foams in Amerisleep AS2 are Certi-PUR certified, which means they are free of harmful chemicals and heavy metals, and are produced without hazardous or toxic materials. Bio-Pur foam is also made with environmentally friendly vegetable oils.
Amerisleep AS2 mattress: customer reviews
AS2 scored 4.7/5 on Amerisleep, based on just over 3,200 reviews (Jan 2023). Reviews of both the hybrid and full-foam versions are grouped together.
A recurring theme throughout all of the reviews is the good job AS2 does in relieving aches and pains, and in particular, back pain. Back and stomach sleepers both report feeling well supported by the mattress, with a recurring theme being how firm Bio-Pur foam is compared to traditional memory foam. Sleepers praise the mattress for being very supportive in these sleeping positions.
Most customers praised the AS2’s temperature regulation, commenting on how well it kept cool all night. Of course as with all things not everyone agreed on this and a few customers found the mattress slept warm.
Most of the low star reviews complained that the mattress was too firm. Firmness preference is very personal, but a few specifically say the mattress is uncomfortable in the side-sleeping position. Usually, we recommend a slightly softer bed for side sleepers, to provide the needed cushioning around the shoulders and hips in this position.
All those commenting on motion transfer agree that this mattress is just as good at isolating motions as anywhere else in the bed. As a general rule, we’d expect the all-foam version to be better in this regard, as the springs increase the responsiveness of the sleeping surface (the two versions are bundled together here, so we can’t support that with review comments). Assessing long-term durability can be difficult as most reviews are left shortly after purchase, but none suggesting premature wear.
Is the Amerisleep AS2 hybrid any good?
Based on customer reviews, we think this mattress is a great choice for back pain sufferers who sleep on their backs or stomachs. The firmer feel should promote proper spinal alignment in these positions, preventing the sleeper’s hips from sinking too far into the bed. It is also strong enough to support sleepers up to 300 lbs. This wouldn’t be our recommendation for side sleepers of any weight, because the mattress is too firm to relieve pressure points at the hips and shoulders.
The general consensus is that the AS2 does a decent job of keeping late night sleepers cool, with its cooling hood, open cell foam and spaced coils. Expect the hybrid version to sleep cooler than the all-foam variant, if overheating is particularly an issue for you.
We also recommend the Amerisleep AS2 to anyone who shares a bed, with plenty of reviews praising the motion isolation offered here (the all-foam version should be your choice if motion isolation is your priority, as coils will always add some bounce). But overall, this is a mattress that will work for many sleepers and can be a godsend if you suffer from back pain.
