They range from stiff (AS1) to delightfully gentle (AS2) (As5). Amerisleep mattresses are also available in all-foam and hybrid versions.

Today, we’ll focus mostly on the all-foam models. Find out more about the hybrid models. We’ll start by looking at the AS3 Hybrid, which is their most popular hybrid model.

Amerisleep Mattress Firmness and Feel


The topic of firmness has been mentioned a few times. The Amerisleep mattress is distinguished by its broad range of firmness options. Let’s discuss the degree of firmness of each Amerisleep mattress, and the way it is felt.

How Firm Are The Amerisleep Mattresses?

Every Amerisleep mattress is firm in its own unique way. The Amerisleep AS1 is more rigid than the average mattress with an 8/10 rating that is on the more firm side of the scale. AS2 AS2 is the second softest model. It scores 7.5/10 however it is heavier than average. With scores of 6.5/10, the Amerisleep AS3 is right in the middle of the firmness range. This is because the Amerisleep AS4 and AS5 is the AS4 and AS5 are two of the softest models following that. The AS4 is more comfortable than average at 6/10. The AS5 is more comfortable than average at 5.5/10.

However the firmness of these mattresses will be dependent on your height and weight. On the other hand, these mattresses may appear more firm when you press deeper into the mattress and get to the support layers if you are heavier. If you are a lighter person, though, you may find the five mattresses considerably softer.

 

Sleeping On The Amerisleep Mattresses


I spent a significant amount of time in each of the five mattresses, trying them in various sleeping positions. It is evident that each differed in their performance!

Amerisleep AS1

AS1

As one of the more firm mattresses of the Amerisleep series, the AS1 could be too firm for back sleepers. The support is excellent however, the comfort layer isn’t thick enough to allow our hips to fully sink into it. We were dissatisfied. On your back, you would like your hips to sink in for a bit in order to keep your spine in a neutral position while you sleep.

If we lie on our sides and sleep on our backs, we experience lots of pressure on our shoulders as well as our hips due to the AS1. We’ll look at the soft variations in the coming moments and discover how they relieve stress.

The Amerisleep AS1 really shines while we sleep on our stomachs. People who sleep on their stomachs need a mattress that provides the hips with support. If the hips aren’t adequately support, their spine may be pulled out of alignment. Amerisleep AS1 offers adequate spinal support, thus this shouldn’t be an issue.

Amerisleep AS2

AS2

Since the AS2 is softer than the AS1, we get a better balance of support and comfort while we sleep with our backs. Our hips are properly bowed and the top foam layers are pushing up into the lumbar area.

The AS2 isn’t firm enough for side sleeping as we push ourselves into the mattress and feel tangled up around our shoulders and hips. After some nights, we could see this causing significant discomfort and the pain.

We can feel some decent support in our hips when stomach sleeping on the Amerisleep AS2. If you prefer to sleep on your stomach then you’ll find that the Amerisleep AS1 mattress is your best way to go.

Amerisleep AS3

AS3

A mattress that is medium-firm like the Amerisleep AS3 is ideal for back sleepers. Therefore, it’s not a surprise that the AS3 is one of our top options for those who sleep on their backs. The Bio-Pur foam on top offers a little contouring to our bodies while keeping us in the right position. It’s among the best mattresses for back sleepers in the Amerisleep varieties.

There is virtually no stress on my shoulders or hips when I lie on my side using AS3. AS3. This larger layer of Bio-Pur foam is actually cushioning our joints, unlike the previous experiences we had when using AS1 or AS2.

In our bellies The Bio-Pur foam does us no favours. When it comes to pressure reduction, it’s incredible, but we’re not getting adequate support for our hips.

Amerisleep AS4

AS4

We’re currently in the realm of a mattress that’s soft. Since AS4 is the AS4 mattress has been rated as Amerisleep’s 2nd most supple, we are getting less support when we lie on our backs. Lumbar support is not as strong and we’re sinking down the mattress a bit.

The Amerisleep AS4 mattress performs best when placed on its side. It’s sinking in thanks to a huge 4 inches of Bio-Pur, as well as our hips and shoulders are feeling almost no strain.

In the case of stomach sleeping, a mattress that is good for side sleeping isn’t the ideal. The Amerisleep AS5 is no exception, and it doesn’t give us the assistance we need.

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep Liberty Box Spring

There is a layer of Active Flex in the Amerisleep AS5, which is their softest and most luxurious model. As a result, we feel more support for our heads and shoulders as we lay upon our backs.

The AS5 is an excellent option for those who sleep on their sides because it is the softest mattress. The weight of the world disappears as we sink into the soft comfort layers.

For stomach sleepers, the A5 does not provide enough support, regardless of it’s Active Flex foam. If we are sleeping with our backs on the ground, we like sleeping on our backs, we prefer the Amerisleep AS1 and AS2.

What Is the Feel of the Amerisleep Mattress?


The foam that is used in the majority of Amerisleep mattresses is similar in feel , and it is soft and firm at the same time. Although we may sink quite in the middle when lying on these mattresses, we’re having no difficulty moving around even. The Bio-Pur foam that is used in all five mattresses varies from one to the next, and we sink into soft mattresses more. Take a look at our Amerisleep vs Tuft & Needle comparison to see how they stack up against another responsive mattress. Check out how Amerisleep and GhostBed perform against a latex mattress in our Amerisleep comparison. GhostBed comparison.

Average Weight Sleepers – 130 lbs- 230 lbs

The Amerisleep AS3 is the one that offers the greatest comfort and support for middle-weight back sleepers, but the AS2 is a better choice for those who need extra support. If you are between both the AS4 and AS5 the weight categories, then you should consider the AS4. The Amerisleep AS1 is the most firm mattress designed for stomach sleepers in that weight class!

Heavyweight Sleepers – Over 230 lbs

AS1 or the AS1 or AS2 by Amerisleep is the ideal choice for people who weigh more and want to sleep on their backs on a mattress that is firmer. It is possible that the AS3, AS4, and AS5 could not be able to withstand their increased weight. The Amerisleep AS4 and AS5 will be suitable for people who are heavier and want to lie on their backs. It is the Amerisleep AS5 is a better choice for those who weigh more than 300 pounds. Even if they plan to sleep with stomachs, the AS1 is the best choice however their size could cause it to be insufficient.

Lightweight Sleepers- Under 130 lbs

Light back sleepers require an appropriate mattress that isn’t too firm, as this will prevent their hips from sinking in the bed. Their best option would be to choose one of the two Amerisleep AS3 models or the Amerisleep AS4 (if they want something that is softer). AS3, AS3, AS4, and AS5 will provide the best pressure relief for those who sleep on their sides due to its modest weight however, the AS5’s extra features may not be necessary for those who sleep on their side. They’ll get all the help they need on either AS1 or AS2 when they’re sleeping.

 

Amerisleep Mattress Construction


There are certain similarities in the Amerisleep mattresses, including the utilization of the similar materials. Concerning the comfort layers there are some significant variations.

Amerisleep AS1

There is a permeable cover on the Amerisleep AS1 mattress, like there is on all the Amerisleep mattresses. Bio-Pur Foam is a material that’s found on the top layer of all Amerisleep mattresses, is that top 2″ of mattress’s comfort layer. A plant-based, breathable foam that’s more comfortable and flexible than conventional memory foam is what we’re calling this new material. It’s also more eco-friendly than other mattress foams since it’s open-celled. Bio-Core foam, which is 8 inches thick, gives additional support for the mattress.

Amerisleep Mattress Performance


Let’s take a look at how Amerisleep mattresses do! See how they did with regards to coolness, movement transfer and edge support. Read on.

Sleeping Hot Or Cold

Based on our experience, Amerisleep mattresses do not generate excessive heat when sleeping. The Bio-Pur foam is created to keep the mattress cool, as we stated earlier. If you are sleeping in Amerisleep mattresses, you should not overheat like you do on other mattresses.

The coil and latex mattresses are great for keeping you cool at night if you have a major problem with overheating. Hybrid mattresses are ideal for those who sleep hot because they’re more comfortable and breathable.

Motion Transfer

Although they’re more responsive than other mattresses mattress brands, they have a lower motion transfer coefficient. Due to Bio-Pur’s motion isolation and motion isolation, if you are sleeping with a partner and you move around, it shouldn’t disrupt the mattress.

The thicker layers of Bio-Pur foam on the AS3 and AS4 make them perfect for couples seeking the best mattress.

Edge Support

Edge support varies among the Amerisleep mattresses. The more firm models allowed us to feel more comfortable sitting or sleeping on the edge of them (the AS1 and AS2). We felt less edge support, especially while we are lying down, when we upgrade to the more soft models.

Durability

All of Amerisleep’s mattresses are constructed of high-density material and are constructed to last. As a result we predict that these mattresses will endure between seven and ten years in the minimum.

Off-gassing

The Amerisleep mattresses have some early off-gassing, but this is to be expected considering the fact that they’re shipped in the form of a box. For a mattress purchased online the scent of chemicals should disappear within 48 hours.

Noise

When we roll around on Amerisleep mattresses and sleep, they do not produce obvious noise. In the end, you won’t be able to hear your spouse’s movements around the house at evening.

Sex

Mattresses from Amerisleep are more responsive, which could make them suitable for sex, as per this review. If you choose an AS4 mattress or AS4 or AS5 mattress, you could sink deeper and experience difficulty moving your partner around.

Warranty Info

All Amerisleep mattresses come with a 100-night sleep trial and a 20-year warranty.

Amerisleep Hybrid Mattress Review


Alongside Amerisleep’s renowned all-foam mattresses now makes hybrid options. The Amerisleep AS3 Hybrid model is a mix of the all-foam AS3 model and we’re here to discuss our experience with it.

The support layers make up the main distinction between these two models. AS3 Hybrid has zoned pocketed coils, while AS3 all-foam has a foundation polyfoam base. However, like the AS3’s all-foam counterpart it is also available in it’s AS3 Hybrid features Bio-Pur foam as the top layer.

The AS3 Hybrid’s coils provide it with more support than the AS3 mattress’s all-foam counterpart. This means it’s a good choice for heavier individuals who need additional support. As a result, the AS3 Hybrid mattress has a higher ventilation because of the coils, which makes it a cooler mattress overall. If you’re looking for a price, this AS3 Hybrid mattress is going cost around $200 more than the AS3 all-foam mattress.

The Amerisleep all-foam mattresses are the most suitable choice for those on a tight budget or are in the lighter end in the range. If you are heavier or require an additional mattress that’s permeable and breathable, the Amerisleep Hybrid models are the best option.

 

Summary Amerisleep Liberty Box Spring


Overall, I think that the Amerisleep mattresses are fantastic.

So many sleepers can choose an Amerisleep which is suitable for them because of the many options available.

The mattresses are extremely cool to the touch, and they provide excellent comfort and support at a reasonable price.
