Amerisleep AS2 Overview


Bouncy - The Amerisleep AS2 is a highly responsive and buoyant bed, which allows for smooth mobility on its top surface. This makes it excellent for combination sleepers, as it would allow them to switch sleeping positions easily on their bed, without feeling stuck.

Good for Back Pain - The Amerisleep AS2 mattress allows for a healthy spine alignment for back sleepers. It fills their lumbar area, distributes their weight equally on the top, and keeps them in a healthy sleep posture. This helps people with back pain and prevents pressure buildup while sleeping on your back.

Good Motion Isolation - Being an all-foam bed, the Amerisleep AS2 provides an excellent motion isolation performance. This makes it a great option for couples who have different sleeping styles and don’t want to disrupt each other’s sleep.


Not Good for Side Sleepers - Side sleepers usually need a softer mattress that can cushion their pressure points. However, The Amerisleep AS2 is a bit more firm than average mattresses, making it not suitable for these folks. If you fall into this category, then the Amerisleep AS5 would be a great option for you, as it is on the softer side.

Who we Recommend the Amerisleep AS2 for

Combination Sleepers - Combination sleepers should find the Amerisleep AS2 very comfortable. It has a bouncy feel to it that allows those folks to change their sleeping positions seamlessly all night.

Couples - When we recommend a bed to couples, we usually think of motion isolation and edge support. For motion isolation, this bed does an excellent job at absorbing motion, allowing you to enjoy a night of uninterrupted sleep. Similarly, it has decent edge support that would allow you to use the entire sleep surface of the mattress.

Hot Sleepers - The Amerisleep AS2 is a great option for those who sleep hot or live in a warm area. It has an open-cell memory foam that allows for a steady airflow through the mattress layers. It also has a Refresh Cooling Cover that gives it a cool, refreshing feel all night.

Unboxing the Amerisleep AS2

The Unboxing experience of the Amerisleep AS2 mattress was smooth and hassle-free. It arrived to us compressed in a box. The box has two handles and is light and easy to carry due to the fact that foam is naturally a light material, so you shouldn’t face a problem carrying it to your desired room. To unbox it, you simply take it out of the box, place it on your bed, carefully cut the plastic wrap, and leave it to fully expand.

When we unboxed the Amerisleep AS2 mattress, we noticed that it took a couple of hours to fully expand into its full 12-inch height. We also noticed that it expanded all the way to its very edges. Such good edge expansion makes your bed look better and indicates that it has great edge support.

Most bed-in-a-box mattresses release an overpowering, irritating odor once they are unboxed, known as off-gassing. Yet, the Amerisleep AS2 bed produced a faint smell that disappeared with a strong airflow. This shows that it is a safe bed that won’t emit any harsh chemicals and toxins into your bedroom.

Overall, we found the unboxing experience of the Amerisleep AS2 to be hassle-free and seamless which is definitely a plus for Amerisleep.

Firmness, Feel and Comfort For Amerisleep AS2

The Amerisleep AS2 Firmness

The firmness of any mattress is a subjective matter, as it depends on your body weight and preferred sleeping position. However, it is important to opt for a mattress that meets your own specific needs. A mattress that is too soft or too firm for you may negatively impact your sleep quality and overall well-being.

Amerisleep AS2 firmness scale

The Amerisleep AS2 achieved a 7/10 on our firmness scale, with 1 being the softest and 10 being the firmest. This makes it on the firm side of mattresses, which could be a plus for a wide range of sleepers. Back and stomach sleepers, in particular, would enjoy the firmness of this level the most. It would help them sleep in a healthy posture, and maintain a perfect spinal alignment.

On the contrary, side sleepers would find this bed too firm for them. They usually go for a soft mattress that can hug their shoulders and hips, and prevent pressure buildups in those areas. Therefore, the Amerisleep AS5 would be a better fit for side sleepers, as it is on the soft side.

The Amerisleep AS2 Feel

The Amerisleep AS2 has a soft plush cover that gives it a comfortable feel. The cover also wicks away moisture, offering you a dry and refreshing sleep surface. When we slept on the AS2 bed for the first time, we felt that it distributes our body weight evenly on its surface, which offers optimal support and spinal alignment.

Overall, we felt that the Amerisleep AS2 has a welcoming sleep surface that feels comfortable, soft, and with a neutral temperature.

The Amerisleep AS2 Comfort

How comfortable you feel while sleeping on a mattress is definitely subjective, as it also depends on your body weight, preferred sleeping position, and the kind of materials you like in your mattress. The Amerisleep AS2 is an all-foam bed that has a firm feel, which makes it ideal for back and stomach sleepers.

For back and stomach sleepers, this bed would make them perfectly aligned and lifted on top. It would also help prevent excessive sinkage, which protects back and stomach sleepers from pressure buildup and offers them healthy sleep.

Side sleepers, however, would find this bed too firm for them. They wouldn’t be able to cradle their shoulders and hips, which leads to pressure buildups in these areas.

Constructions, Materials, and Design

Materials and Design

The AS2 is a 12” all-foam mattress that features Amerisleep’s high-quality materials. Its Refresh Cooling Cover is specifically designed by Amerisleep to maintain a cool, refreshing sleep surface. The mattress also features a layer of Bio-Pur foam, which is a better, more cooling version of traditional memory foam. For the base layer, the mattress includes a layer of high-density foam that makes the mattress supportive, even for those who weigh more than 300 lbs.


Here is what is inside the Amerisleep AS2:

Amerisleep AS2 layers

  1. Cover - The mattress has a Refresh Cooling Cover that is designed by Amerisleep to give the AS2 a cool and comfortable feel.
  2. Comfort Layer - The comfort layer of the mattress is made with Bio-Pur foam, which is an updated version of the traditional memory foam. It has an open-cell structure, so it makes the mattress more breathable.
  3. HIVE Transition Layer - This layer acts as a transition between the comfort and support layers of the Amerisleep AS2 mattress. It is also zoned to support your neck, back, and legs, and add more cushioning to your hips and shoulders.
  4. Support Core - The support core of this mattress consists of high-density polyfoam. It makes the bed supportive, so heavy-weight sleepers shouldn’t face a problem sleeping on it. This layer also makes the AS2 bed more durable and resistant to premature sagging.

Performance of the Amerisleep AS2


If you are a hot sleeper or simply don’t like the feeling of a warm mattress while sleeping, then good cooling performance is essential for you, while looking for a new mattress.

Amerisleep AS2 mattress

We did our standard tests to evaluate the cooling performance of the Amerisleep AS2 mattress. The first test consists of taking 20-minute naps on each side of the mattress. When we did this test, we found that the mattress maintained a cool temperature, regardless of the sleeping position.

The second test involves sleeping on the mattress for a full night in all sleeping positions. The result of this test was not a surprise, as the mattress slept cool all night.

The Amerisleep AS2 mattress features cooling and breathable materials, such as the Refresh Cooling Cover and open-cell Bio-Pur foam. Such materials allow it to sleep cool all night, which is an important detail for hot sleepers.

We rated the Amerisleep AS2 mattress’ cooling performance a 4.7/5.


Mattresses that have good responsiveness performance allow sleepers to move freely and smoothly on the bed surface. Therefore, looking for a bouncy mattress with good responsiveness performance is super important.

We tested the responsiveness of the Amerisleep AS2 mattress by doing our standard responsiveness test. Our test consists of dropping a 20 lbs ball onto the mattress and then removing it. This test helps us examine how fast the mattress recovers to its original shape after being subjected to pressure. When we did this test, we found that the mattress took 0.9 seconds to regain its initial form.

This shows that the Amerisleep AS2 is a highly responsive mattress that has a bouncy feel to it. This was not a surprise to us, as the comfort layer of Bio-Pur foam gives the mattress a responsive feel. This would be a great feature for combination sleepers, as it would allow them to switch sleeping positions freely, without feeling stuck.

We rated the Amerisleep AS2 mattress’ responsiveness a solid 4.7/5.

Motion Isolation

Motion isolation is very important, especially if you are a light sleeper who doesn’t want to be disturbed by your partner’s tossing and turning on the bed all day. To assess the Amerisleep AS2 mattress’ ability to isolate motion, we ran a couple of our tests.

In the first test, we placed a glass full of water on one side of the bed and dropped a heavy ball on the other side. This test allows us to observe the motion transferred to the glass of water. When we conducted this test, we discovered that the ball drop hardly moved the water inside the glass.

Another test that we did was that we tried rolling on one side of the bed and had our partner report the motion felt on the other side of the bed. It was no surprise that this test showed the same result, as little to no motion was felt on the other side of the bed.

Such good motion isolation performance was expected from the Amerisleep AS2 mattress, as all foam mattresses usually do an excellent job at isolating motion. This makes this bed a great choice for couples who have different sleeping styles. It would allow them to move freely on the bed, and switch sleeping positions, without disturbing each other.

We rated the Amerisleep AS2 mattress’ motion isolation performance a solid 5/5.

Edge Support

Strong edge support is an important attribute to look for in a new mattress. A strong edge support would allow you to use up the entire sleep surface of the mattress and sleep near the edges, without feeling that you are going to roll out of bed. Mattresses with strong edge support also tend to last long, as you won’t be forced to sleep only towards the center of your bed, which prevents premature sagging. We performed our standard edge support tests to evaluate the Amerisleep AS2 mattress’ edge support performance.

Amerisleep AS2 mattress

The first test we did consisted of applying pressure to the edges of the mattress and observing how much it sank. This test indicates if the mattress has strong edges that make you feel supported while sleeping. When we did this test, we found that the edges of the AS2 mattress didn’t sink to much due to the dense polyfoam support core.

The second test we did involved sitting on the mattress’ edges and seeing how well it held our body weight. The results of the test also indicated that the edges of the mattress do a decent job of holding body weight.

The results of our tests showed that, despite being an all-foam bed, the Amerisleep AS2 has decent edges. This would allow you to sleep or sit near the edges of your bed, without worrying about falling.

We rated the edge support of the Amerisleep AS2 mattress a 4.5/5.


We did our standard noise test to see if the Amerisleep AS2 mattress makes any noises or squeaks. Our test consists of dropping a heavy ball onto the surface of the mattress and using highly sensitive mics to see if it makes any noises or squeaks.

Our tests showed that the Amerisleep AS2 mattress is within the “silent” mattresses. It causes no noise due to not having coils in its construction, which makes it an ideal choice for light-sleepers who are easily disturbed by noise.

We rated the Amerisleep AS2 mattress’ noise performance a well-deserved 5/5.


A mattress that is good for sex needs to have a number of elements, such as bounce, edge support, and great cooling performance. Based on our performance tests so far, the Amerisleep AS2 mattress should be a great choice for sex.

It is a responsive, bouncy mattress that allows for easy movement on its surface. It also has a support core of dense polyfoam that makes its edges supportive, so you shouldn’t worry about rolling out of bed. Finally, its cooling and breathable materials allow it to stay cool and comfortable all night.

We rated the Amerisleep AS2’s sex performance a solid 5/5.

Pressure Relief

When we sleep in our preferred sleeping position, we usually feel pressure buildup in different body areas, which are known as pressure points. It is highly advisable to opt for a mattress that relieves your pressure points, so you can enjoy a comfortable and healthy sleep.

We tested the Amerisleep AS2 mattress’ pressure relief performance by sleeping on each side and examining where pressure tends to build up. The pressure map below illustrates the results.

Amerisleep AS2 pressure map

Back sleepers - Back sleepers should feel super comfortable sleeping on this bed. It well supports them and allows for a healthy sleep posture. It also supports their lumbar area, which eases the pressure on their back.

Stomach Sleepers - The mattress’ firm feel would keep stomach sleepers well aligned, as it would prevent their hips from sinking too much. This relieves pressure on their lower back and promotes healthy sleep.

Side Sleepers - Side sleepers would experience pressure buildup while sleeping on the AS2 mattress. The firm feel of this bed wouldn’t cushion their hips and shoulders, which leads to feeling some pressure in those areas.

We rated the Amerisleep AS2’s pressure relief performance a 4/5.
