Amerisleep AS2 Mattress Firmness and Feel

When you’re hunting for a new mattress, it’s critical to consider firmness and feel before committing to a purchase. These factors play a big role in determining whether a mattress is well-suited to your preferred sleep position(s) and other sleep needs. So let’s kick off the detailed portion of this review with a look at the Amerisleep AS2’s firmness and feel!

How Firm Is The Amerisleep AS2?

We ranked the Amerisleep AS2 around a 7.5 out of 10 on the firmness scale. The industry standard for medium-firmness is 6.5/10, so this suggests the AS2 is firmer than average.

Note that firmness is a bit subjective, and a person’s body weight will influence their perception of a given mattress’s firmness. That said, most people will likely perceive this mattress to be firm.

Sleeping On The Amerisleep AS2 Mattress

The Amerisleep AS2 mattress felt like a great match for back sleeping. We felt our hips sink in for a bit of pressure relief, but not so far that they pulled the spine out of alignment. Meanwhile, the top foam layers pressed into the lumbar area to offer plenty of support.

Amerisleep AS2 - Back Sleeping

In our experience, the Amerisleep AS2 is decidedly too firm for side sleeping. We felt bunched up around the shoulder and hip even during a short trial. We expect that folks who sleep in this position on a nightly basis would experience some serious discomfort and pain after just a few nights. If you’re a side sleeper, check out our picks for best mattress for side sleepers.

While stomach sleeping on the Amerisleep AS2, we experienced decent support under our hips. This support helped keep the hips elevated and aligned with the spine, which promotes proper spinal alignment. That said, strict stomach sleepers might prefer the firmer Amerisleep AS1 or another firm mattress.

What Does the Amerisleep AS2 Feel Like?

Each mattress in the Amerisleep line features a similar foam feel that is simultaneously pressure-relieving and responsive. Because the AS2 is firmer and has a thinner comfort layer than many of the models in this line, sleepers won’t sink into the mattress very much. It’s also a touch bouncier than the plusher models.

Average Weight Sleepers – 130 lbs – 230 lbs

Folks who weigh closer to 230 pounds should enjoy plenty of spinal support and a touch of pressure relief while back sleeping on the Amerisleep AS2, while lighter folks might find the mattress too firm. This mattress is definitely too firm for side sleeping. The Amerisleep AS2’s firm nature could make it a decent match for average-weight stomach sleepers, who should enjoy plenty of spinal support.

Heavyweight Sleepers – Over 230 lbs

Heavyweight back sleepers who weigh close to 230 pounds could experience decent support on this mattress, while folks who weigh more than 300 pounds will want to look for a dedicated mattress for heavy people. Same goes for stomach sleepers: The Amerisleep AS2 mattress could be a decent match for folks who weigh closer to 230 pounds, but heavier people will need a more supportive bed. The Amerisleep AS2 is decidedly too firm for heavyweight side sleepers.

Lightweight Sleepers – Under 130 lbs

Lightweight back and side sleepers will almost certainly find that the Amerisleep AS2 feels too firm in these positions. That firmness could be a boon for lightweight stomach sleepers, who should enjoy plenty of support on this mattress.

Amerisleep AS2 Mattress Construction

You now know what it’s like to sleep on top of the Amerisleep AS2, so it’s time to take things a step further! Let’s dive deep into this mattress’s construction and assess how its materials influence performance and feel.


The Amerisleep AS2 features a thin cover that’s very breathable. This allows air to flow through the surface of the mattress.

Comfort Layers

The Amerisleep AS2’s main comfort layer takes the form of 2” of Bio-Pur foam. This material is plant-based, open-celled, and CertiPUR-US certifiedmeaning it’s more eco-friendly than conventional foams.

Amerisleep AS2 - Construction

Underneath the Bio-Pur foam, there’s a 3” HIVE Transition layer. This layer is zoned to be a touch softer around the shoulder and hips (for added pressure relief) and a bit firmer around the head, back, and legs (for extra support).

Support Layer

The base layer on the Amerisleep AS2 is made from 7” of high-density Bio-Core foam. This material lends support and structure to the mattress overall.

Mattress Height

The Amerisleep AS2 mattress is 12” tall.

Amerisleep AS2 Mattress Performance

By now you know a lot about the Amerisleep AS2 (including its firmness, feel, and construction), but there are a few key performance indicators to assess before we wrap up this review. We put this mattress through a range of tests with regard to temperature regulation, motion transfer, edge support, and more. Also, make sure to check out our Amerisleep mattress comparisons.

Sleeping Hot Or Cold

The Amerisleep AS2 boasts two design elements that could help it sleep cooler: its breathable cover and open-celled Bio-Pur foam. Still, this is an all-foam mattress, so it’s quite possible that it could trap some heat.

Motion Transfer

The Amerisleep AS2 handles motion transfer fairly well. The Bio-Pur foam does a good job of absorbing motion and minimizes disturbances across the surface of the mattress. If you’re very concerned about motion transfer, consider one of the models with a thicker Bio-Pur foam layer (such as the AS4).

Edge Support

The Amerisleep AS2 boasts great edge support. The mattress’s firm feel extends to its perimeter, and we felt secure while sitting and lying down near the edge.


This is a very durable mattress that should last longer than many all-foam beds. This durability is reflected in the Amerisleep AS2’s extra-long warranty.


We did observe some off-gassing from the Amerisleep AS2. This should dissipate within a few days.


We didn’t observe any notable noise from this mattress. That’s thanks in large part to the Amerisleep AS2’s all-foam construction.


A good mattress for sex makes it easy to change positions on top of the bed, and the Amerisleep AS2 fits the bill. Its responsive nature means partners shouldn’t feel stuck in this mattress.

Warranty Info

The Amerisleep AS2 comes with a 100-night sleep trial and a 20-year warranty.

Amerisleep Company Policies

Before you buy an AS2 mattress, make sure you understand the fine print policies.


The Amerisleep AS2 comes with an extra long 20-year warranty. If your AS2 mattress has manufacturing defects like tears in the fabric or cracks in the foam, Amerisleep will repair or replace your mattress.

The first 10 years of the warranty are a full replacement warranty, and the second 10 years is a prorated warranty. This means after the first 10 years of your warranty, if you have an issue with your mattress that is covered by the warranty, Amerisleep will replace your mattress for a portion of its cost and you will have to pay for the other portion.

Sleep Trial

The Amerisleep AS2 mattress comes with a risk-free, 100-night sleep trial period. Your sleep trial begins as soon as the mattress arrives at your door. If you ordered an adjustable base through Amerisleep, the sleep trial does not begin until the base is also delivered.

Return Policy

If you decide during your 100-night sleep trial period that the AS2 mattress isn’t right for you, you can contact Amerisleep to begin an exchange or return. If you choose to return the AS2 mattress, you can receive a full refund.

Because it can take some time to adjust to a new mattress, Amerisleep asks that you wait 30 days before beginning a return or exchange. If you do need to complete an exchange or return within the first 30 days of your trial, Amerisleep charges a $99 processing fee.

You may be wondering how the AS2 mattress compares to some other options. We’ll compare the AS2 to Amerisleep’s popular AS3 mattress down below.

If you want to compare the AS2 to other options, check out our Amerisleep mattress comparisons.

Amerisleep AS2 vs AS3

As we mentioned at the beginning of our review, Amerisleep offer a line of five mattresses to accommodate the needs of different types of sleepers. With the AS3 being of the most popular options from Amerisleep, we wanted to compare the AS2 vs AS3 mattress.

First off, each of these mattresses feature a similar construction. Both mattresses use the same celliant cover and top layer of soft, bio-based memory foam that’s designed to offer a breathable, pressure-relieving night’s sleep. Each mattress is also 12” tall and comes with the same warranty, trial period, and customer service since they are from the same brand.

Amerisleep AS3 - construction and foam layers

Where the mattresses begin to differ is in the firmness and feel. The AS3 has a thicker comfort layer, making the AS3 mattress a little softer and better for side sleepers. The AS2 has a firmer feel and makes a good fit for stomach and back sleepers who need more support.

The AS2 is also the more expensive mattress, but the value of the mattress really comes down to your personal sleep preferences.

Who Should Get The Amerisleep AS2? 

  • People who like a firmer mattress
  • Stomach and back sleepers who need more support
  • Heavier people who need more support

Who Should Get The Amerisleep AS3? 

  • People who like a softer mattress
