Let’s face it – buying a new bed-in-a-box mattress can be overwhelming. Just searching online for five minutes, you are bombarded with ads and companies that claim their mattress is the best. However, in my many years of reviewing mattresses, I have learned that there really is no one best mattress for everyone.

That being said, companies like Amerisleep make it so much easier to find the right fit for you. They offer a line of both all-foam and hybrid mattresses that range in terms of firmness. They really offer something for everyone!

Amerisleep Mattress Overview

As we said above, Amerisleep is all about offering their customers options. They offer five mattress models – the AS1, AS2, AS3, AS4, and AS5. They range from extremely firm (AS1) to luxuriously soft (As5). In addition, the Amerisleep mattresses come in both all-foam and hybrid models.

We’ll be setting our sites primarily on the all-foam models today. If you want to learn more about the hybrid models, read below as we review the AS3 Hybrid, their most popular hybrid model.

While the Amerisleep mattresses are all quite different in terms of their firmness, comfort, and support, the whole line is going to be a better choice for certain shoppers.

  • Shoppers who want a number of firmness options
  • Fans of memory foam mattresses
  • Couples who want a mattress to cut down on motion transfer

Amerisleep Mattresses Video Review

Right now, you might not be able to try out all of the Amerisleep mattresses in a store. So, we did it for you! Watch our video review to see me put the Amerisleep mattresses to the test. We leave no stone unturned, so check it out!


Amerisleep Mattress Firmness And Feel

We’ve mentioned firmness a few times already. Its wide variety of firmness options is what really sets the Amerisleep mattress apart. Let’s discuss exactly how firm each Amerisleep mattress is and what if feels like.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress has its own firmness. Starting on the firmer end of the spectrum, the Amerisleep AS1 is an 8/10, much firmer-than-average. Moving to the next softest model, you have the AS2; this is 7.5/10, still firmer-than-average. Right in the middle of the firmness range, we have the Amerisleep AS3 with a score of 6.5/10. Following that, we get the two softest models, the Amerisleep AS4 and AS5. The AS4 is close to a 6/10, softer-than-average, and the AS5 is close to a 5.5/10.

All this being said, the firmness of these mattresses is going to depend greatly on your size and weight. On one hand, if you are a heavier person, these mattresses might feel firmer as you press deeper into the mattress and hit the support layers. On the other hand, if you are a lighter person, you might feel like these five mattresses are much softer.

Sleeping On The Amerisleep Mattresses

I spent a good deal of time on all five mattresses and tried them out in different sleeping positions. You’ll see they did perform differently!

Amerisleep AS1

The AS1 is definitely the firmest mattress in the Amerisleep line, and it does feel a bit too firm for back sleeping. The support is fantastic, but the comfort layer isn’t really thick enough to let our hips sink in. If you sleep on your back, you do want your hips to sink in a fair amount, so that your spine stays neutrally aligned.

Amerisleep AS1 - Back Sleeping

The AS1 is not really designed for side sleeping, and we can feel some significant pressure on our shoulders and hips. We’ll look at the softer models in a moment and see how they relieve pressure better.

When we are stomach sleeping on this mattress, the Amerisleep AS1 really shines. Stomach sleepers want a mattress to support them under their hips. If they don’t get enough support, their hips will bow in, and this could take the spine out of alignment. Thankfully, this shouldn’t be an issue with the Amerisleep AS1, and we experience good spinal support. Out of these five, it is the best mattress for stomach sleepers.

Read the full Amerisleep AS1 mattress review.

Amerisleep AS2

The AS2 is a bit softer than the AS1 and, because of this, we are getting more of a balance of comfort and support while back sleeping. We can feel our hips bow in the right amount, and the top foam layers are pressing up into the lumbar area.

Amerisleep AS2 - Back Sleeping

However, the AS2 is still too firm for side sleeping; we are driving into the mattress and feel bunched up around our shoulders and hips. We could see this leading to some serious discomfort and pain after a few nights.

Stomach sleeping on the Amerisleep AS2, we can feel some decent support under our hips. That being said, if you sleep just on your stomach, the Amerisleep AS1 will be the way to go.

Read the full Amerisleep AS2 mattress review.

Amerisleep AS3

The AS3 is Amerisleep’s medium-firm mattress and that is usually what back sleepers want to look for. It’s no surprise then that the AS3 is probably the best mattress for back sleepers in the whole line. We feel held up by the mattress and, at the same time, the top layer of Bio-Pur foam provides some contouring for our curves. Out of the Amerisleep models, it is one of the best mattresses for back sleepers.

Amerisleep AS3 - Back Sleeping

Side sleeping, the AS3 is a very good match for us, and we can feel almost no pressure on our shoulders and hips. Unlike our experience on the AS1 and AS2, we don’t feel bunched up, and that thicker layer of Bio-Pur foam is really cushioning our joints.

When we move to our stomachs, that thicker layer of Bio-Pur foam is doing us no favors. It’s fantastic when it comes to pressure relief, but we aren’t getting enough support under our hips.

Read the full Amerisleep AS3 mattress review.

Amerisleep AS4

Now, we’re getting into soft mattress territory. The AS4 is Amerisleep’s second softest mattress and, because of this, we are starting to lose some support when we are back sleeping. We aren’t getting quite enough lumbar support, and we are dropping into the mattress somewhat.

Side sleeping, the Amerisleep AS4 mattress is at its best. A whopping 4″ of Bio-Pur foam is allowing us to sink into the mattress, and we are feeling almost no pressure on our shoulders and hips. It is one of the best mattresses for side sleepers on this list.

Amerisleep AS4 - Side Sleeping

As is usually the case, a mattress that is great for side sleeping isn’t the best for stomach sleeping. The Amerisleep AS5 is no exception and is too soft to provide us with the necessary support.

Read the full Amerisleep AS4 mattress review.

Amerisleep AS5

The Amerisleep AS5 is their softest, most luxurious model, but it also contains a layer of Active Flex in its construction. This also provides some more support to the top of the mattress, and we feel held up while back sleeping.

Given that it is the softest mattress, the AS5 is also a great fit for side sleeping. We sink into the thick comfort layers and feel the pressure melt away.

Amerisleep AS5 - Side Sleeping

Even with the addition of the Active Flex foam, the A5 is not quite supportive enough for us when we are stomach sleeping. Again, we much prefer the Amerisleep AS1 and AS2 when we are sleeping in this position.

Read the full Amerisleep AS5 mattress review.

What Do The Amerisleep Mattresses Feel Like?

The Amerisleep mattresses all feature a similar foam feel that is comfortable but also responsive. Lying down on these mattresses, we do sink in a fair amount, but we have no real trouble moving around. Now, these five mattresses do feature different amounts of that Bio-Pur foam, and we do sink into the softer mattresses more. To see how they compare to another responsive mattress, check out our Amerisleep vs. Tuft & Needle comparison. Also, read the Amerisleep vs. GhostBed comparison to see how they stack up against a latex mattress.

Average Weight Sleepers – 130 lbs – 230 lbs

Average weight back sleepers should feel the best balance of comfort and support on the Amerisleep AS3, but if they require more support, the AS2 should be a better option. Average weight side sleepers should prefer the AS4 or possibly the AS5 if they are at the heavier end of this weight range. Stomach sleepers in this weight range will most likely prefer the Amerisleep AS1 as it is the firmest model!

Heavyweight Sleepers – Over 230 lbs

Heavyweight people should prefer back sleeping on one of the firmer Amerisleep mattresses such as the AS1 or AS2. They might not find that the AS3, AS4, AS5 provide them with enough support for their heavier weight. Side sleeping, heavier people should get the cushioning they need on the Amerisleep AS4 or AS5. If they are much heavier, closer to 300 lbs, they will most likely want to opt for the Amerisleep AS5. Stomach sleeping, the AS1 will be their best bet, but it still might not be supportive enough for someone of their weight.

Lightweight Sleepers – Under 130 lbs

Lightweight back sleepers are going to want something that is not extremely firm because this will not let their hips sink in the right amount. They will be better off choosing either the Amerisleep AS3 or the Amerisleep AS4 (if they want something a bit softer). For side sleeping, lightweight people should get the best pressure relief on the AS3, AS4, AS5, but they might not need the extra features of the AS5. Stomach sleeping, they will get all the support they need on either the AS1 or the AS2.

Amerisleep Mattress Construction

The Amerisleep mattresses do have their similarities, namely, they feature a lot of the same materials. However, when you look more closely at the comfort layers, you’ll see some noticeable differences.

Amerisleep AS1

The Amerisleep AS1 mattress is 10″ tall and features the same breathable cover found on all the Amerisleep mattresses. Its comfort layer consists of 2″ of Bio-Pur Foam, a material that is found on top of all the Amerisleep mattresses. It is plant-based and designed to be more breathable and responsive than standard memory foam. It is open-celled and also more eco-friendly than many other types of mattress foam. Below that, there are 8″ of Bio-Core foam that will add support to the mattress.

Amerisleep AS1 - Construction

Amerisleep AS2

The Amerisleep AS2 is 12″ tall and, yep, it has the same breathable cover as the other models. Similar to the AS1, it also has 2″ of Bio-Pur foam right on top of the mattress. Below, it also features 3″ of a HIVE transition layer that is zoned to provide more support in some areas and more comfort in others. The support layer is 7″ of that same Bio-Core foam.

Amerisleep AS2 - Construction

Amerisleep AS3 

The Amerisleep is 12″ tall, features the standard Amerisleep cover, and boasts a 3″ layer of Bio-Pur foam in its top comfort layer. This is 1″ more than you get on top of the AS3. Below that, there is a HIVE transition layer, but it is 2″ thick instead of 3″. Finally, the support layer contains 7″ of Bio-Core foam.

Amerisleep AS3 - construction and foam layers

Amerisleep AS4

The Amerisleep AS4 is also 12″ tall and, you guessed it, has the same breathable cover! Noticing a trend here? The top layer of Bio-Pur foam is even thicker than the top layer of the Amerisleep AS3 (it is 4″ thick!). Below that, there is only 1″ of the HIVE transition foam and, on the bottom of the mattress, there are 7″ of Bio-Core foam.

Amerisleep AS4 - Mattress Construction

Amerisleep AS5

The Amerisleep AS5 is 14″ thick and guess what the cover is like? Hint: it’s the same as the other mattresses. On top, it has 3″ of Bio-Pur foam and then a layer that is unique to the AS5. It is 2″ of something called Active Flex that is soft and bouncy as well. The base layer is 7″ of the Bio-Core foam you find in the other Amerisleep mattresses.

Amerisleep Mattress Performance

We put the Amerisleep mattresses to the test! Keep reading to see how they performed with regard to cooling, motion transfer, and edge support.

Sleeping Hot Or Cold

The Amerisleep mattresses do not sleep extremely hot in our experience. As we said above, the Bio-Pur foam is designed not to trap heat and to keep the mattress cool. So, when you sleep on the Amerisleep mattresses, you shouldn’t be overheating too much.

That being said, if you have serious issues with sleeping hot at night, you might still want to look for a mattress with latex or coils in it. See below for how the Amerisleep Hybrid mattresses are more breathable and could be better for hot sleepers.

Motion Transfer

While the Amerisleep mattresses are on the responsive side, they do handle motion transfer well. The Bio-Pur foam isolates motion to one side of the mattress so, if you sleep with a partner, you shouldn’t disturb each other when you each move around.

Anyone who needs the best mattress for couples might want to opt for the AS3 or the AS4 with their thicker layers of Bio-Pur foam.

Edge Support

The Amerisleep mattresses do vary in terms of their edge support. We personally felt more secure sitting and lying down near the edge of the firmer models (the AS1 and AS2). Moving up to the softer models, we feel less edge support, especially when we are lying down.

Amerisleep Mattress - Edge Support


The Amerisleep mattresses are all durable and contain some very high-density materials. Based on this, we would say these mattresses will last for at least between seven and 10 years.


There is some initial off-gassing with the Amerisleep mattresses but this is unsurprising given that they come in a box. This slight chemical smell is normal for an online mattress and should go away after 48 hours.


The Amerisleep mattresses don’t make any significant noise when we roll around on them. So, you shouldn’t hear your partner when they move around at night.


The Amerisleep mattresses are more responsive, so they could be good mattresses for sex. However, with the AS4 or AS5, you might sink in further and find it harder for you and your partner to move around.

Warranty Info

The Amerisleep mattresses all come with a 100-night sleep trial period and a 20-year warranty.

Amerisleep Hybrid Mattress Review

We’ve been talking a lot about the all-foam Amerisleep mattresses, but let’s not forget that they offer hybrid models as well! We’d like to briefly discuss our time on the Amerisleep AS3 Hybrid model and how it differed from the all-foam AS3 model.

The main difference between these two models can be found in their support layers. The all-foam AS3 features base polyfoam, while AS3 Hybrid contains zoned pocketed coils. However, like the all-foam AS3, the AS3 Hybrid has Bio-Pur foam right on top.

Amerisleep AS3 Hybrid - Construction And Layers

With the addition of coils, the AS3 Hybrid does feel more supportive than the all-foam AS3 mattress. This might make it a better option for heavier people who need something to support their extra weight. The coils leave more room for airflow, making the AS3 Hybrid a better cooling mattress overall. The AS3 Hybrid is also going to cost more than the all-foam AS3 mattress (around $200 more for a Queen-size).

Looking at this specific comparison, the Amerisleep all-foam mattresses are going to be better if you want to spend less on your mattress or if you are on the lighter side. If you are heavier or need a more breathable mattress, the Amerisleep Hybrid models should be the way to go.

How Does Amerisleep Compare To Other Mattresses?

It’s always a good idea to do some comparison shopping! We’ve put together some short comparisons with Amerisleep’s biggest competitors. Also, check out our long list of Amerisleep comparisons to see how they stack up against all the major brands!

Amerisleep Vs Leesa

The Leesa is an all-foam mattress that features a proprietary LSA200 foam on top. It is more responsive than memory foam and makes for a more balanced foam feel. This is not too different from the Amerisleep mattresses with their soft-yet-responsive Bio-Pur foam.

Leesa Mattress - Construction And Layers

The Leesa mattress is close to a 6.5/10 in terms of firmness, similar to what we find with the Amerisleep AS3 mattress. So, the AS1 and AS2 are going to be firmer than the Leesa, and the AS4 and AS5 are going to be softer. Speaking of price, the Leesa is more affordable than Amerisleep’s most affordable mattress.

The Amerisleep mattresses are going to be a better choice if you want, well, choices. Side sleepers who need more comfort or stomach sleepers who need more support can find it on an Amerisleep mattress. The Leesa should be better for back sleepers and those who want to spend less on their mattress.

Read our full Amerisleep vs Leesa mattress comparison to learn more. If you want to see how they compare to other foam mattresses, check out our Amerisleep vs. Bear and Amerisleep vs. Puffy comparisons.

Amerisleep Vs Casper

The Casper mattress a unique Zoned Support system that makes it feel firmer toward the center and softer toward the head and foot. This is intended to make the Casper feel firmer and more supportive when you are back sleeping and stomach sleeping and softer when you are side sleeping.

Casper Mattress - Construction And Foam Layers

While four of the Amerisleep mattresses also feature a zoned transition layer, this zoning is not as pronounced as what you find in the Casper mattress. With the Casper, the center zone really presses into the lumbar area, and it is more difficult to feel the zoning in the Amerisleep mattresses.

The Casper has a firmness of 7/10, and it is softer than the AS1 and AS2 and firmer than the AS3, AS4, and AS5. Speaking of price, the Casper costs less than the AS1, Amerisleep’s most budget-friendly model.

The Amerisleep should be better if you want firmness options, and if you are trying to find the best match for your sleeping position. The Casper is going to be better for back sleepers who want some more lumbar support and those who want to spend less on their purchase.
