Is Amerisleep AS2 a Good Mattress For You?

Before I dive into the details, here’s my recommendations for who the Amerisleep AS2 is and isn’t good for.

Who I Recommend the Amerisleep AS2 Mattress For

  • The AS2 is a bit on the firmer side and I found that it did a good job of keeping my hips from sinking in while I was on my back and stomach. This is important for back and stomach sleepers, as it maintains their spinal alignment.
  • The AS2 performed well on both the motion transfer and edge support tests. These are the two tests I reference most when trying to decide if a mattress would be good to share with a partner.
  • I think the AS2 is a good fit for those who like the feel of memory foam, but don’t want to feel stuck or sink too deeply into the mattress. The AS2 offers some contouring, but you can still move easily.

Who I Don’t Recommend the Amerisleep AS2 Mattress For

  • Because this mattress is on the firmer side, I wouldn’t recommend it for side sleepers or combination sleepers who frequently sleep on their side. The AS2 doesn’t offer enough pressure relief on the hips and shoulders, and that buildup in pressure leads to pain over time.
  • If you love the feeling of sinking deep into memory foam, I also wouldn’t recommend the Amerisleep AS2. You’ll feel more on top of the mattress, rather than in it.

How Firm Is the Amerisleep AS2 Mattress?

Now that we’ve gone through the overview on this mattress, let’s dive into the firmness. People will feel the firmness of a mattress differently based on different weights and body types. Instead of just giving my opinion on the overall firmness of the Amerisleep AS2 I brought in three other people to give it a try as well. This range of opinions should give you a better idea of the firmness you can expect from this mattress.

Amerisleep AS2 Firmness Graph
Amerisleep AS2 Firmness Graph

A 6.5/10 is generally considered to be medium firmness and with the AS2 responses averaging almost 8/10 on the firmness scale, you can expect this mattress to be pretty firm. I rated the mattress at a 7.5/10, and while I did feel the classic memory foam feel on top, I found the transition layer below to be pretty firm.

I would say that the AS2 provides good support to keep the back aligned well and bounce to keep the sleeper from feeling stuck in the mattress when changing positions.

The initial feel when pressing into the AS2 is of the memory foam comfort layer, which allows me to sink in and contours to my hand a bit. When I applied more force and pressed into the mattress with both hands I went through the memory foam and began to interact with the poly foam layer beneath. This firmer layer provides a smooth transition from the soft layer of memory foam to the firm base layer at the bottom.

Amerisleep AS2 Mattress Performance

Firmness level is just one factor in a mattress, so I’ve also tested the Amerisleep AS2 for performance in different sleeping positions, motion isolation, and more.

Testing the Amerisleep AS2 Mattress In Different Sleeping Positions

Everyone is different, so a mattress will feel different to different people. What position you primarily sleep in and how much you weigh can change what a mattress will feel like to you—and ultimately, determine if it will be a good fit for you.

Is the Amerisleep AS2 a Good Mattress for Light Sleepers (Under 130 pounds)?

  • Light Back SleepersLight back sleepers should be comfortable on the Amerisleep AS2, especially if they prefer a firmer mattress. They won’t sink in much, so their spine should stay aligned, but they should still get good pressure relief from the foam.
  • Light Side Sleepers For light side sleepers, the Amerisleep AS2 is probably going to be too firm. I’d recommend a softer mattress for pressure relief on hips and shoulders.
  • Light Stomach SleepersLight stomach sleepers should also enjoy the Amerisleep AS2. This firmer mattress will keep their hips elevated as they sleep, preventing lower back pain.

Is the Amerisleep AS2 a Good Mattress for Average Weight Sleepers (130 – 250 pounds)?

  • Average Weight Back SleepersThe Amerisleep AS2 will be a good fit for average weight back sleepers. Back sleepers may sink in a little, but will primarily feel that they are lying on top of the mattress, rather than in it.
  • Average Weight Side SleepersFor side sleepers, this mattress is probably too firm to allow them to sink into the mattress for pressure relief on the hips and shoulders. I’d recommend looking at one of the softer mattresses in the Amerisleep line.
  • Average Weight Stomach SleepersStomach sleepers should enjoy the Amerisleep AS2. Because it is firmer, it should keep the hips elevated. Also, good pressure relief in the chest will ensure stomach sleepers breathe easy.

Is the Amerisleep AS2 a Good Mattress For Heavy Sleepers (over 250 pounds)?

N.B. The Amerisleep AS2 is supportive enough for heavy people up to about 300 pounds, but sleepers above that should opt for a mattress designed for heavy people.

  • Heavy Back SleepersHeavy back sleepers should find the Amerisleep AS2 fairly comfortable. Being a firmer mattress, it should give them good support and keep their spine well aligned.
  • Heavy Side SleepersHeavy side sleepers will sink into this mattress more than light and average sleepers, but it still may be too firm and not offer enough pressure relief to be comfortable for side sleeping.
  • Heavy Stomach SleepersBecause the Amerisleep AS2 is a firmer mattress, stomach sleepers should be comfortable, as their hips will stay elevated. However, if you’re worried about sinking in too deeply, a hybrid mattress may provide more support.

Amerisleep AS2 Mattress Pain Relief Performance

Sleeping on the wrong mattress can lead to pain in your back and joints over time. To prevent pain, it’s important to find the right blend of pressure relief and support. Pressure relief will prevent pain from buildup in pressure points like shoulders and hips, while support will prevent pain from being out of proper alignment.

In order to give a visual representation of where someone may feel pressure points while lying on the Amerisleep AS2, I placed a pressure map on top of the mattress and lied on my back, side, and stomach. In the image below, pressure will be represented from blue (low pressure) to red (high pressure).

Back PainThe results from lying on my back show blue for low pressure across my body, which matches what I felt while on the mattress. I could feel the foam layers filling in the space beneath my lower back, which is a plus in preventing pain for those that sleep on their back.

Shoulder Pain – As I mentioned before, the AS2 is designed to be the second firmest mattress in the Amerisleep line, which helps to explain the higher pressure shown on the results above. This increased pressure on a firmer mattress can cause issues in the shoulders, which dig into the mattress a bit more. I did feel the increase in pressure while lying on the AS2 and if you are a strict side sleeper I would recommend a softer mattress from Amerisleep’s line.

Hip Pain – Like with shoulders, the firmness of this mattress can lead to increased pressure buildup in the hips. To prevent hip pain, I’d recommend a softer mattress.

Amerisleep AS2 Mattress Performance for Couples

If you share a mattress with a partner, there are a few important things to consider before you buy. Namely, motion transfer, sex, cooling, and edge support. Let’s take a look at how the Amerisleep AS2 performs in each of these categories.

Motion Transfer

If you are going to share your bed with a partner, you will want to know what it will feel like when the other person gets into and out of bed or tosses and turns during the night. This next test is helpful in showing the intensity of motion that is detectable from one side of the mattress to the other.

For this test I dropped a 10-pound steel ball from heights of 4 inches, 8 inches, and 12 inches and measured the disturbance on the other side of the mattress. This should be pretty intuitive: the bigger the lines, the bigger the disturbance.

The 4 inch drop simulates a small disturbance to the bed, such as someone changing positions across the mattress, and the result shown above is a good outcome when compared to other mattresses I have put through this test.

The 8 and 12 inch drops are meant to show the disturbance that would be felt when someone climbs or jumps into bed. These results are a bit higher than the 4 inch drop, as should be expected, but they are about average for foam mattresses.


A mattress that works well for sex is generally responsive and allows you to move around easily. Even though the Amerisleep AS2 is an all-foam bed, I found it to still be quite responsive and didn’t feel stuck or like I was sinking down into the foam. That responsiveness, plus good motion isolation, should make this a good mattress for sex.


When two people share a bed, it can sometimes lead to overheating from two times the body heat. In order to combat that, couples will want a mattress that has good cooling capabilities.

The Amerisleep AS2 has an open-cell structure foam that allows for more airflow within the mattress than traditional memory foam mattresses. That airflow will prevent heat building up, and keep you and your partner cooler throughout the night.

Edge Support

If you’re going to share your mattress and need to use the entire surface then edge support is something you are going to want to take a look at. While some foam mattresses struggle to live up to the edge support of traditional innerspring mattresses, I have seen good performances from other Amerisleeps in the line, so I was excited to see that the AS2 showed good edge support when I sat and laid along the edge of the bed.

What Is the Amerisleep AS2 Mattress Made Of?

The Amerisleep AS2 is an all foam mattress made of three layers and totaling 12 inches in height. The mattress is meant to be the second firmest in the Amerisleep line and uses a combination of a thin memory foam layer and a poly foam transition layer to provide pressure relief without the feeling of being stuck in the mattress. Let’s take a look inside!

Amerisleep AS2 Cover

Cover – The cover is the company’s Refresh Cooling Cover. The material aims to keep sleepers extra cool by drawing heat away. The company also says the fabric uses minerals to help promote daily performance and energy.

Comfort – The comfort layer of the AS2 is made of 2 inches of memory foam. Memory foam allows the sleeper to sink in for pressure relief and is known for the classic feel of contouring to the body. At times memory foam can have a reputation for trapping body heat, but Amerisleep uses their Bio-Pur foam with an open-cell design to defend against overheating.

Transition – Below the comfort layer is 3 inches of poly foam, creating what Amerisleep calls the HIVE transition layer. This layer is convoluted (wavy design) to allow space for air to flow through the mattress for temperature regulation and cooling.

This layer is made of a pretty firm foam to provide some initial support and has a quick response to pressure, which gives the mattress some bounce. This bounce and support helps keep the sleeper from feeling stuck in the mattress as they change positions. The firmer foam used in this layer provides a transition from the soft comfort layer above to the base of the mattress below.

Base – The foundation of the mattress is Bio-Core foam, a 7 inch layer of high density poly foam. This is a firm foam that provides support to the layers above as well as deep compression support to the sleeper. This layer also provides the mattress with its shape and lends some durability to the structure.

Amerisleep AS2 Mattress Unboxing and Off-Gassing

The Amerisleep AS2 is a bed-in-a-box, meaning that it will arrive at your house compressed and rolled into a box. To unbox the mattress, all you need to do is open the box, remove the mattress, unroll it, and cut off the packaging. The mattress will be heavy, so be sure to enlist a friend to help.

Once the mattress is open and on its base, it will start to inflate. The mattress will also need to decompress and off-gas, which means it will release gasses trapped during compression. I’d recommend placing your unboxed bed in a ventilated room for 24 hours before using it, so it can fully decompress and off-gas.

My Final Thoughts about Amerisleep AS2 Mattress

Now that we’ve gone over all the nitty gritty details, here are my final thoughts on the Amerisleep AS2 mattress.

My Favorite Things About the Amerisleep AS2 Mattress

I really liked this bed for back and stomach sleepers. Because the mattress is on the firmer side, I found that it supported my hips and prevented them from sinking into the mattress. This will help prevent back pain for back and stomach sleepers.

I also think this mattress is a good option for couples, because the Amerisleep AS2 performed so well on both motion transfer and edge support tests.

And finally, I appreciated how the Amerisleep AS2 gave me the feeling of a memory foam mattress, but I didn’t sink in so deeply that it was difficult to move. This is a plus for combination sleepers, as well as people with mobility issues.

My Amerisleep AS2 Mattress Complaints

Because of the firmness and slight buildup in pressure on the hips and shoulders, I would say this is not the best mattress for strict side sleepers. A softer mattress that offers more contouring and pressure relief will work better.

Amerisleep AS2 Mattress Policies and FAQs

Amerisleep AS2 Mattress Vs

After testing out the Amerisleep AS2, I thought it would be helpful to compare this mattress to some of its competitors, Purple and Casper. Let’s go over the similarities and differences between these beds.

Amerisleep AS2 Mattress vs Purple Mattress

  • The Purple is also a foam mattress, but features the unique hyperelastic grid on the top layer that has made Purple famous. This grid has open-cells, for airflow, and creates a sensation of floating on top of the mattress.
  • Like the Amerisleep AS2, the Purple mattress is also very responsive, which is great for combination sleepers or anyone who loves a bouncy mattress.
  • And when it comes to pain relief, the Purple mattress is great at relieving pressure, making it a comfortable mattress for all sleeping positions.

Amerisleep AS2 Mattress vs Casper Mattress

  • The Casper mattress is one of the most well-known mattresses in the bed-in-a-box market, and for good reason. It’s a memory foam bed that features Zoned Support, which provides extra support under areas like head, shoulders, and hips.
  • Being a firm mattress, the Casper is a great option for back sleepers, especially those who like a firm feel.
  • The Casper mattress also sleeps cool, thanks to its AirScape open-cell foam, which allows for breathability.
  • For more information, read my full Casper mattress review.

Other Models from Amerisleep

Now that I’ve put the Amerisleep AS2 head-to-head with its competitors, let’s compare it to some other Amerisleep mattress models.

Amerisleep AS2 Mattress vs Amerisleep AS3 Mattress

  • The AS3 is the medium-firm mattress in Amerisleep’s line of five mattresses. Medium-firm is a firmness level that is comfortable for a wide variety of sleepers, which is why this model is Amerisleep’s most popular.
  • However, that firmness level means that the mattress isn’t firm enough for strict stomach sleepers.
  • The Amerisleep AS3 also offers great pressure relief, thanks to the memory foam that offers just enough sinkage, without feeling stuck in the mattress.
  • Learn more in my full Amerisleep AS3 mattress review.

Amerisleep AS2 Mattress vs Amerisleep AS1 Mattress

  • The Amerisleep AS1 is the firmest mattress in the line, making it a great option for stomach sleepers.
  • The AS1 also uses open-cell foam to promote airflow within the mattress, making it a good option for hot sleepers.
  • Additionally, the Amerisleep AS1 is the lowest priced mattress available from the brand.
  • For more information, read my full Amerisleep AS1 mattress review.
