Things to Consider Before Buying an Amerisleep Memory Foam Mattress

As with all things related to shopping for new stuff, particularly furniture, you need to know about all the factors that you are paying for. This can help you avoid being disappointed when the mattress arrives and it is not to your standards or liking. So, with the Amerisleep Memory Foam Mattress, you need to consider the following things:

It lacks “bounce” qualities

Since all Amerisleep Mattresses are memory foam mattresses, it does not have that spring or bounce quality. Mattresses that have that quality are mainly latex, innerspring, or hybrid beds. That is because memory foam beds focus on pressure relief more than any other types of mattresses. They conform to your body, which allows for pressure relief to happen.

However, this would also mean that movement is highly restricted. This makes it harder for one to move around from the bed. It also makes it quite difficult for users to get up from the mattress itself. That said, this would depend on what your priorities are. If you need pressure relief more than movement, then the Amerisleep Mattress is for you.

It does not have the best edge support

This feature always puts memory foam mattresses at a disadvantage. That is because it is known among the industry that these mattresses do not have the best edge support. The reason behind this is, simply put, they lack the firmness that latex and innerspring beds offer. Because it does not have superb edge support, you might not feel comfortable sitting down on the edges.

If you are also a person that tends to move a lot when you sleep, then it would be best that you not sleep near the edge. That is because you can easily fall off from beds that do not offer much edge support. However, if you do not particularly move around a lot, and you do not mind having too soft edges, then Amerisleep Mattresses are a fantastic option.

It might not be suitable for side sleepers

For people that prefer to sleep on their sides, they would need an equal balance of support and comfort. This helps prevent misalignment of the spine when sleeping in this position. Unfortunately, Amerisleep Mattresses might not be ideal for side sleepers. That is because these mattresses might be too soft, which means there won’t be much support for the hips.

Features & Benefits

Even after reviewing all the considerations before purchasing an Amerisleep Mattress and you find that it is still worth buying, then let us start with all the wonderful things about it. Because Amerisleep Memory Foam Mattresses have five different mattresses (AS1, AS2, AS3, AS4, and AS5) with varying firmness options. So, we will breakdown each one just for you.

amerisleep as4 review construction


AS1 Mattress

Quick Description

Formerly called the Americana mattress, this one is the firmer option among Amerisleep beds. Even though it offers a firm feel, it still provides a level of comfort, just enough for pressure relief.

Construction & Design

The AS1 Mattress is 10 inches thick and consists of only two layers. The first layer, which is the comfort layer, is 2 inches of memory foam. The second and last layer, which is the base of the bed, is an 8-inch thick Bio-Core support foam. This is the reason why it offers more support rather than comfort.

Firmness Level

On a firmness scale of 1 to 10, with one being 1 soft as a feather and 10 being as hard as a rock, the AS1 Mattress scores a firm 8. Therefore, it is a fantastic option for those looking for a supportive mattress.


If interested in purchasing the AS1, know that it ranges from $850 to $1,400 – depending on the size that you are getting. This puts it at average when it comes to price, which should already entice most customers.

Best For

Since the AS1 offers more support rather than comfort, it is ideal for people that sleep on either their backs or stomachs. This is quite true especially for stomach sleepers. They would need a firmer mattress, so that they won’t misalign their spine.


AS2 Mattress

Quick Description

Like the AS1, the AS2 Mattress, previously known as the Revere mattress, offers a firm option for all users; although, the AS1 mattress might be more firm than this one. Other than that, the AS2 offers dynamic support and back pain relief. It is also Amerisleep’s most popular mattress.

Construction & Design

When you compare this bed with the AS1 in terms of construction, know that it is slightly thicker, measuring in at 12 inches. And, it has three layers. The first layer or the comfort layer, is made of a 2-inch Bio-Pur memory foam. Next we have the transitional layer, which is 3 inches of polyfoam. Lastly, we have the 7-inch Bio-Core base layer.

Firmness Level

Again, on a firmness scale, the AS2 scores a 7.5, which is a medium-firm feel.


With the AS2, this is where the prices start to increase for each mattress. Now, the AS2 offers a price range of $1,049 to $2,198.

Best For

Since this mattress has a medium-firm feel, it is best for people who love to sleep on their backs.


AS3 Mattress

Quick Description

Previously named the Liberty mattress, the AS3 is considered to be the best-selling Amerisleep mattress, and it is also their flagship product. On top of that, it is designed to adapt to most body types and sleeping positions. This makes it excellent for pressure relief.

Construction & Design

The AS3 and the AS2 Mattresses are quite similar in terms of size and number of layers. The AS3 has a 3-inch memory foam comfort layer on top. A 2-inch poly foam layer directly underneath. Finally, it also has a 7-inch support base layer. However, the difference is in the feel, as the AS3 offers a softer, more pressure relieving quality.

Firmness Level

With the AS3, it scores a medium 7 on the firmness scale. This makes it, again, a tad bit softer than the AS2 and even more so than the AS1.


For its prices, the AS3 offers a price range of $1,149 to $2,398. This puts its prices slightly higher than the rest of its competition. However, considering the dynamic pressure relief qualities, we would say that it is worth the money.

Best For

Since the AS3 offers a softer feel, it is best for side sleepers. However, since it is also the most versatile among all Amerisleep mattresses, it makes them best for all sleeping positions, including those that sleep with a combination of all positions.


AS4 Mattress

Quick Description

Now, we are slowly going down on the firmness level with the AS4 Mattress, but it is only the second most soft among all five mattresses. This one offers a softer feel without compromising on the support aspect. On top of that, along with the AS3, it is Amerisleep’s flagship model. It is also previously called Colonial.

Construction & Design

In terms of size, it is difficult to distinguish the AS2, AS3, and AS4, since they all have a 12-inch all foam construction. The top layer is a 4-inch Bio-Pur+ Memory Foam. Next is its 1-inch transitional layer directly underneath it, and lastly, the 7-inch base support layer.

Firmness Level

The AS4 has a firmness level of 6.5 on the firmness scale. This means, like the AS3, it offers superb comfort and also equalizes the amount of support.


For the AS4, you will be looking at a price range of $1,399 (Twin) to $2,698 (Split King). This makes it not ideal for people who are on a budget. But, if you can afford it, then it is something that you might regret if you do not get it.

Best For

Since it offers a softer profile than any Amerisleep we discussed so far, it works best for side sleepers. Back sleepers can also find comfort when sleeping on this bed. And, a combination of the two positions can also work. However, it is important to note that this would only apply for people who are lightweight to those with average weights. People who weigh heavier might find themselves getting “stuck” when sleeping.


AS5 Mattress

Quick Description

Finally, we have made it to the last Amerisleep Mattress, the AS5, or what is formally known as the Independence mattress. This is the thickest of all mattresses, measuring in at 14 inches. On top of that, it is also the softest of all. Because of its plush feel, it is the best option for those looking for pressure relief.

Construction & Design

As stated earlier, this is the thickest mattress at 14 inches. However, like the rest, it is also made up of three layers of all memory foam. Starting with the topmost part, we have the comfort layer, which is 3 inches of pure memory foam. Next is something unique to the AS5 alone, which is a 2-inch “Active Flex” layer, which conforms greatly with your body. Now, we have the transitional layer which is measured at 2 inches. Finally, we have the 7-inch Bio-Core support base layer.

Firmness Level

On the firmness scale, the AS5 scores a soft and plush 5.5. This makes it excellent for those seeking pressure relief for those aching joints. However, this would also mean that the mattress does not have much of a support system in place.


For the AS5 Mattress, it depends entirely on the size. It can go from $1,849 for a Twin to $3,798 for a Split King. So, this makes it quite expensive. This is because Amerisleep uses only the finest materials for this bed.

Best For

Since it does provide heavenly comfort, the AS5 mattress is best for only side sleepers. That is because it offers a fantastic cushion for the shoulders and hips. People who prefer to sleep in other positions might find the mattress too soft. This would allow for the spine to misalign, causing pain and aches.
