The Amerisleep AS3 Overview
Great Motion Isolation - The Amerisleep AS3 does a great job at isolating motion from one side of the bed to the other. This makes it a great option for couples with different sleeping styles, or very light-sleepers who are easily disturbed by movement.
Cooing and Breathable - The Amerisleep AS3 has a cooling cover that gives it a refreshing feel. Its memory foam layers are also breathable and allow for an airflow through its internals. This gives your AS3 mattress a cool, dry feeling to enjoy all night.
Generous Trial Period - There is no risk in buying the AS3 mattress, as Amerisleep offers a generous free trail period of 100 nights. This gives you plenty of time to try and adjust to your new mattress. However, if you end up not liking it, you can return it for a full refund during the trial period.
Too Soft for Stomach Sleepers - Stomach sleepers usually need a firmer mattress that can support and keep them in a perfect alignment. However, being on the softer side of mattresses, the Amerisleep AS3 allows the hips of stomach sleepers to sink, which could cause lower back pain. Therefore, if you fall into this category, you can opt for one of Amerisleep’s firmer beds.
Who we Recommend the Amerisleep AS3 for
Couples - When we recommend a bed to couples, we usually think of motion isolation and edge support. For motion isolation, the Amerisleep AS3 does a great 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, without feeling that you will roll out of bed.
Hot Sleepers - The Amerisleep AS3 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 AS3
The Amerisleep AS3 arrived to us compressed in a box that was slightly heavy. However, it had two handles that allows two people to easily carry it to the desired room, so make sure to have someone to help you while unboxing this mattress. 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 AS3 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 a good edge support.
Most bed-in-a-box mattresses release an irritating, irritating odor once they are unboxed, known as chemical off-gassing. Yet, the Amerisleep AS3 bed only produced a faint new-product 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 AS3 to be hassle-free and seamless which is definitely a plus for Amerisleep.
Firmness, Feel and Comfort For Amerisleep AS3
The Amerisleep AS3 Firmness
The firmness of any mattress is a subjective matter, as it depends on your body weight and preferred sleeping position. Yet, it’s important to opt for a mattress with a firmness level that suits your specific needs. A mattress that it too firm or soft for you may negatively impact your sleep health and overall well-being.
The Amerisleep AS3 achieved a 5/10 on our firmness scale, with 1 being the softest and 10 being the firmest. This makes it a medium-firm mattress, which is typically the firmness level that satisfy the need of most sleepers.
For back sleepers, this firmness level should give them the needed support, while cradling their back and filling their lumbar area. Side sleepers, as well, would enjoy the firmness level of this bed, as it is soft enough to hug their pressure points. However, stomach sleepers need a firmer bed due to the fact that the AS3’s medium feel would allow for excessive sinkage and cause them back pain.
The Amerisleep AS3 Feel
The Amerisleep AS3 has a soft, cooling and moist-wicking cover. It is plush and gives the mattress a luxurious feel. The mattress also has a comfort layer of memory foam that makes it feel comfortable and relieving to your pressure points.
Overall, we found that the Amerisleep AS3 has one of the most welcoming sleeping surface we have tried. Therefore, we recommend it for those who want a luxurious, plush sleeping experience.
The Amerisleep AS3 Comfort
The amount of comfort you get from a mattress depends on your body weight, preferred sleeping position, and the kind of materials you like. Sleepers who enjoy the contouring feel of memory foam mattress would find the Amerisleep AS3 mattress very comfortable.
Back and side sleepers, especially, would enjoy sleeping on this bed. Back sleepers would feel that their weight is evenly distributed on the surface, and side sleepers would feel that the mattress cushions their pressure points. However, stomach sleepers may experience some lower back pain due to the soft feel of the AS3.
|Sleeper Weight||Back Sleepers||Side Sleepers||Stomach Sleepers|
|Lightweight (Under 150 lb)||Excellent||Excellent||Good|
|Average (150 – 250 lb)||Excellent||Excellent||Fair|
|Above Average (Over 250 lb)||Very Good||Very Good||Not Recommended|

The AS3 is a 12” all-foam mattress that features Amerisleep’s high-end materials. Its Refresh Cooling Cover is specifically designed by Amerisleep to maintain a cool, dry sleep surface.
The mattress also has 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 AS3:
- Cover - The mattress has a Refresh Cooling Cover that is designed by Amerisleep to give the AS3 a cool and comfortable feel.
- Comfort Layer - The comfort layer of the mattress is made with Bio-Pur foam, which is an improved version of the traditional memory foam. It has an open-cell structure, so it makes the mattress more breathable.
- HIVE Transition Layer - This layer acts as a transition between the comfort and support layers of the Amerisleep AS3 mattress. It is also zoned to support your neck, back, and legs, and add more cushioning to your hips and shoulders.
- 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 AS3 bed more durable and resistant to premature sagging.
Performance of The Amerisleep AS3 Mattress
If you sleep hot 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.
We did our standard tests to assess the cooling performance of the Amerisleep AS3 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 most of the night.
The Amerisleep AS3 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 feature for hot sleepers.
We rated the Amerisleep AS3 mattress’ cooling performance a 4.6/5.
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 AS3 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 evaluate 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 1.3 seconds to regain its initial form.
This shows that the Amerisleep AS3 is has decent responsiveness and some bounce to it it. This was not a surprise to us, as the comfort layer of Bio-Pur foam gives the mattress a responsive feel. This makes it a decent option for combination sleepers, as it would allow them to switch sleeping positions freely, without feeling stuck.
We rated the Amerisleep AS3 mattress’ responsiveness a solid 4.3/5.
Motion isolation is essential, 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 evaluate the Amerisleep AS3 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 AS3 mattress, as all foam mattresses usually do a very good 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 AS3 mattress’ motion isolation performance a solid 4.8/5.
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 AS3 mattress’ edge support performance.
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 AS3 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 AS3 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 AS3 mattress a 4.3/5.
We did our standard noise test to see if the Amerisleep AS3 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 AS3 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 AS3 mattress’ noise performance a 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. According to our performance tests results so far, the Amerisleep AS3 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 AS3’s sex performance a solid 5/5.
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 AS3 mattress’ pressure relief performance by sleeping on each side and examining where pressure tends to build up. The pressure map below illustrates the results.
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 fills in their lumbar area, which relieves the pressure on their back.
Stomach Sleepers - The mattress’ medium-firm feel might allow the hips of stomach sleepers to sink too much, which causes lower back pain. Therefore, a firmer mattress would be a better option for them.
Side Sleepers - Side sleepers should feel extremely comfortable sleeping on the AS3 mattress. It’s soft enough to cradle their shoulders and hips, which gives them healthy, pain-free sleep.
We rated the Amerisleep AS3’s pressure relief performance a 4/5.
