Amerisleep AS5 Mattress Overview


Soft and Cushioning - The Amerisleep AS5 mattress is on the soft side of mattresses. Actually, it is the softest mattress in the Amerisleep line. Such cushioning feel makes it ideal for side sleepers, as it hugs their shoulders and hips, and sinks in the right places.

Edge Support - Although it has a soft feel to it, the Amerisleep AS5 has great edge support. Thanks to the support core of high-density polyfoam, the edges of the Amerisleep AS5 bed are supportive, allowing you to utilize the entire sleep surface of your bed. This would also make you feel supported while sleeping or sitting near the edges of your mattress.

Motion Isolation - Due to being an all-foam mattress, the Amerisleep AS5 has an excellent motion isolation performance. Foam helps decrease the amount of motion felt on each side of your bed, allowing you to toss and turn all night, without disturbing your partner.

Pressure Relief - The Amerisleep AS5 provides great pressure relief. It cradles your body while sleeping in all positions, which prevents pressure buildup. It also has a zoned support core that is soft where you need it. This promotes healthy sleep, as the A5 mattress keeps you in perfect spinal alignment and sleep posture.

Safe for People with Allergies - The Amerisleep AS5 has a moist-wicking cover that is resistant to dust, fungi, and mildew. This makes it safe for those with allergies, so you shouldn’t feel worried about sleeping on it, as it prioritizes both comfort and well-being.


Not Ideal for Heavy-Weight Sleepers - The Amerisleep AS5 provides the needed support for sleepers who weigh less than 250 lbs. Those who weigh more would sink too much into it, which may cause them discomfort. Heavy-weight side and stomach sleepers, in particular, would feel pressure buildups in their shoulders, hips, and lower back. Therefore, if you fall into this category, you can opt for one of Amerisleep’s firmer mattresses that would give you more support.

Who we Recommend the Amerisleep AS5 Mattress for

Couples - The Amerisleep AS5 has excellent edge support that would allow you and your partner to use the entire sleep surface of the mattress, and feel that your bed is bigger. It also does a great job of isolating motion, allowing you and your partner to be comfortable with your sleeping styles and not disturb each other’s sleep.

Hot Sleepers - The Amerisleep AS5’s cover is cooling and moisture-wicking. It dissipates the heat away from your body and offers you a fresh and dry sleep surface. It also has layers of breathable foam that allow for a steady airflow through the mattress. Such cooling properties make the A5 mattress a great option for hot sleepers.

Side Sleepers - The AS5 bed from Amerisleep is a medium mattress that offers a soft, plush feel. This makes it ideal for side sleepers, as it would provide them with the right amount of sinkage to keep them in a perfect sleep posture. Also, its soft feel would cradle their shoulders and hips, which prevents pressure buildup.

Luxury Shoppers - If you are looking for a high-end, luxurious mattress, then the Amerisleep AS5 bed would be a great option for you. It features high-quality foam, and a plush cover and offers great cooling, pressure relief, and motion isolation performances. Therefore, it is a mattress that can give you a luxurious, well-rounded sleeping experience.

Unboxing the Amerisleep AS5 Mattress

The Unboxing experience of the Amerisleep AS5 mattress was smooth and hassle-free. It arrived to us compressed in a box, of course, since it is a bed-in-a-box mattress. The box was light and easy to carry, as 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 AS5 mattress, we noticed that it took a couple of hours to fully expand into its full 14-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 AS5 bed hardly produced any potent smell. 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 AS5 to be fun and seamless, which is definitely a plus for Amerisleep.

Firmness, Feel and Comfort For Amerisleep AS5 Mattress

The Amerisleep A5 Firmness

The firmness of any mattress depends on your body weight and preferred sleeping position, making it a subjective matter. Yet, it is of great importance to opt for a mattress that suits your specific needs. A mattress that is too firm or too soft for you would negatively affect your sleep quality and overall well-being.

Amerisleep AS5 firmness scale

The Amerisleep AS5 scored a 5/10 on our firmness scale, with 1 being the softest and 10 being the firmest. This shows that it is on the soft side of mattresses, as it has a medium feel to it. This makes it an ideal option for side sleepers, as it would sink in the right places and offer them optimal comfort.

The Amerisleep AS5 is also a good option for back sleepers, as it would hug their back and fill in their lumbar area. As for stomach sleepers, the medium feel would give them both comfort and support and keep them in a healthy alignment.

The Amerisleep AS5 Feel

The Amerisleep AS5 has a plush, cooling, and moist-wicking cover. It is soft to the touch and gives the mattress a luxurious feel. The mattress also has a comfort layer of memory foam that makes it feel comfortable and pressure relieving.

Overall, we found that the Amerisleep AS5 has one of the most welcoming sleeping surfaces we have encountered. Therefore, we recommend it for those who want a luxurious, plush sleeping experience.

The Amerisleep AS5 Comfort

The amount of comfort you get from a mattress highly depends on your body weight, preferred sleeping position, and the kind of materials you like. Sleepers who enjoy the contouring feel of memory foam mattresses would find the Amerisleep AS5 bed very comfortable.

Back sleepers should feel comfortable on this bed, as its soft feel would cushion their back and support their lumbar area. Stomach sleepers would also be in a great sleep posture on this bed, offering them optimal comfort.

However, side sleepers are those who would feel comfortable the most on this mattress. Its soft feel would offer them the right amount of sinkage. It also cradles their hips and shoulders, which offers them great pressure relief.

It is noteworthy, though, that the Amerisleep AS5 wouldn’t be comfortable for sleepers who weigh more than 250 lbs. Its soft feel would allow for excessive sinkage and not enough support. Therefore, a firmer or hybrid mattress would be a better option for them.

Constructions, Materials, and Design

Materials and Design

The Amerisleep AS5 mattress is a 14-inch bed of all-foam layers. It has comfort layers of plush, conforming memory foam, and a support core of high-density polyfoam. This makes the A5 mattress a perfect balance of comfort and support. The mattress also has a breathable, moist-wicking cover that gives it a cool and refreshing feel.

It is also noteworthy that Amerisleep uses an organic alternative for the petroleum-based memory foam in this mattress, which makes it a cleaner, safer memory foam bed.


Here is what is inside the Amerisleep AS5 mattress:

Amerisleep AS5 layers

  1. Cover - The mattress has a stretched polyester cover. It gives the mattress a cool, soft-to-the-touch feel, and is resistant to fungi, mold, and mildew.
  2. Comfort Layer - The 3” comfort layer of the AS5 mattress is made with contouring, pressure-relieving memory foam. It enhances the mattress’ cooling performance, adds a bouncy feel to it, and helps with motion isolation.
  3. Compression Layer - This 2” Active Flex layer adds to the softness of the mattress, which allows you to sink deeper into it. It also adds more bounce to your bed, which promotes easy mobility.
  4. Transition Layer - A 2” layer of zoned polyfoam acts as the transition between the Amerisleep AS5’s comfort layers and support core. Its zoned design improves the mattress’ breathability and adds pressure relief where it’s most needed.
  5. Support Core - The support core of the AS5 mattress is a 7” layer of high-density polyfoam. This helps support your body and distribute your weight evenly on the mattress’ sleep surface. It also offers the mattress strong edges and allows it to be durable.

Performance of the Amerisleep AS5 Mattress


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 AS5 mattress

We did our standard tests to evaluate the cooling performance of the Amerisleep AS5 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 neutral 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 AS5 mattress features cooling and breathable materials, such as the zoned compression layer and cooling cover top. Such materials allow it to maintain a cool sleeping surface all night, making it a great option for hot sleepers.

We rated the Amerisleep AS5 mattress’ cooling performance a 4.5/5.


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 AS5 mattress by doing our standard responsiveness test. Our test consists of dropping a 20lbs 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 0.7 seconds to regain its initial form.

This shows that the Amerisleep AS5 is a highly buoyant bed that has a bouncy feel to it. This was not a surprise to us, as the comfort foam of memory foam gives the mattress a responsive feel. This would be perfect for combination sleepers, as it would allow them to switch sleeping positions freely, without feeling stuck.

We rated the Amerisleep AS5 mattress’ responsiveness a solid 4.8/5.

Motion Isolation

Motion isolation is significant, especially if you are a light-sleeper who don’t want to be disturbed by your partner’s tossing and turning on the bed all day. To assess the Amerisleep AS5 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 had any impact on 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 AS5 mattress, as all-foam mattresses usually do a great 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 AS5 mattress’ motion isolation performance a well-deserved 5/5.

Edge Support

Strong edge support is an important attribute to look for in a new mattress. A strong edge support would make you utilize the entire sleep surface of the mattress and sleep near the edges, without feeling that you are going to fall out of bed. Mattresses with strong edge support also tend to last long, as you won’t feel pressured to sleep only towards the center of your bed, which prevents premature sagging. We performed our standard edge support tests to evaluate the Amerisleep AS5 mattress’ edge support performance.

Amerisleep AS5 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 AS5 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 holds body weight. The results of the test also indicated that the edges of the mattress do a great job of holding body weight.

The results of our tests showed that, despite being an all-foam bed. the Amerisleep AS5 has strong 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 AS5 mattress a 4.7/5.


We did our standard noise test to see if the Amerisleep AS5 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 AS5 mattress is within the “silent” mattresses. It makes zero 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 AS5 mattress’ noise performance a solid 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 AS5 mattress should be an excellent choice for sex.

It is a bouncy, buoyant bed that allows for easy movement on its surface. It also has a support core of dense polyfoam that makes its edges supportive and sturdy, 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 AS5’s sex performance a solid 4.8/5.

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 AS5 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 AS5 pressure map

Back sleepers - Those folks should feel comfortable sleeping on this bed. It cradles 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’ soft feel would hug the body of the stomach sleepers, allowing for a good spinal alignment. However, heavy-weight stomach sleepers may feel pressure buildup in their lower back, as the mattress would allow their hips to sink too much.

Side Sleepers - Side sleepers should experience little to no pressure buildup while sleeping on the AS5 mattress. The soft feel of this bed would cradle their shoulders and hips, where pressure tends to build up. This would offer them a comfortable, healthy sleep.

We rated the Amerisleep AS5’s pressure relief performance a 4.3/5.
