Amerisleep Mattress Firmness And Feel


The subject of firmness has been discussed a few times. The Amerisleep mattress has been distinguished with its wide range of firmness options. Let’s talk about the level of firmness for each Amerisleep mattress as well as how they feel.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress is unique in its firmness way. For instance, the Amerisleep AS1 is a stiffer-than-average mattress with an 8/10 rating that is on the more firm side of the scale. Its AS2 is the next-softest model; it is 7.5/10, which is still harder than usual. With scores of 6.5/10 it is the Amerisleep AS3 is right in the middle of the firmness range. The Amerisleep AS4 as well as the AS5 is the AS4 and AS5 are two of the most soft variants following that. The AS4 is softer-than-average at 6/10, while the AS5 is less abrasive than average at 5.5/10.

Having said that, the firmness of these mattresses will be determined by the height and weight you carry. On the other hand, these mattresses may seem more firm if you push deeper into the mattress and get to the support layers, if you are a heavier person. If you’re heavier, however it is possible that these five mattresses are substantially softer.

 

Sleeping On The Amerisleep Mattresses


I spent a lot of time in each of the five mattresses, evaluating their sleeping positions in various ways. It is evident that they performed differently!

Amerisleep AS1

AS1

As one of the more firm mattresses in the Amerisleep series, the AS1 could be too firm for those who sleep on their backs. Its support is fantastic however, it’s comfort layer doesn’t seem thick enough to let our hips fully sink into it. We were disappointed. If you sleep on your back, would like that your hips sink for a bit in order to ensure your spine remains in a neutral posture as you rest.

If we lie on our sides and sleep on our backs, we experience the stress on our shoulders and hips because of the AS1. We’ll take a closer look at the softer versions in the next paragraph and find out how they ease tension.

The Amerisleep AS1 really shines while sleeping on our stomachs. Those who sleep on their stomachs should have an appropriate mattress that offers support for their hips. If your hips aren’t properly supported, the spine could be thrown out of position. Amerisleep AS1 has adequate spinal support and this shouldn’t be an issue.

Amerisleep AS2

AS2

Because the AS2 is more supple than the AS1 which is why we have an improved balance of comfort and support when we sleep with our backs. The hips are correctly bent, and the top foam layers are pressing into the lumbar region.

The AS2 isn’t firm enough to be used for sleeping on the side; we drive into the mattress and feel bunched in our shoulders and hips. After some nights, we can see this is causing significant discomfort and discomfort.

There is a bit of support under our hips while resting on our stomachs in the Amerisleep AS2. If you prefer to rest on your stomach then you’ll find that the Amerisleep AS1 mattress is your best option to go.

Amerisleep AS3

AS3

A mattress that is medium-firm like that of the Amerisleep AS3 is ideal for back sleepers. It’s not surprising to find that the AS3 is one of our top choices for back sleepers. The Bio-Pur foam layer on top provides a bit of contouring to our contours while also holding us in the right position. It’s among the top mattresses for back sleepers, among the Amerisleep types.

There isn’t much stress on my shoulders or hips when I sleep on my back with the AS3. The 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 isn’t doing us any favours. In terms of pressure reduction, it’s fantastic but we’re not receiving enough support for our hips.

Amerisleep AS4

AS4

We’re now in the realm of a mattress that’s soft. Because the AS4 mattress is Amerisleep’s second most supplemattress, we’re losing some support when sleeping in a back position. Lumbar support is lacking, and we’re sinking into the mattress a little.

The Amerisleep AS4 mattress performs best when placed on its side. We’re sinking into the mattress thanks to a huge 4-inch Bio-Pur, and our shoulders and hips are hardly feeling any strain.

In the case of stomach sleeping mattresses that are ideal for side sleeping isn’t the ideal. The Amerisleep AS5 mattress isn’t an exception, and doesn’t provide us with the help we require.

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep Liberty King Mattress

There’s a layer of Active Flex in the Amerisleep AS5 which is their most soft and luxurious model. As a result, we feel more support for our head and shoulders as we lay on our backs.

The AS5 is a great 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 sleeping The A5 mattress does not offer enough support, regardless of the Active Flex foam. If we are sleeping on our backs, we love more the Amerisleep AS1 and AS2.

What Is the Feel of the Amerisleep Mattress?


The foam that is used in the majority of Amerisleep mattresses has a similar feel , and it is soft and firm at same simultaneously. Despite the fact that we sink quite slightly when we lay on these mattresses, we have no problem moving about in any way. The Bio-Pur foam utilized in all five mattresses varies in thickness, and we sink more into the soft mattresses more. Take a look at our Amerisleep vs Tuft & Needle comparison to find out how they compare against another responsive mattress. Check out how Amerisleep and GhostBed perform against a mattress made of latex in our Amerisleep comparison. GhostBed comparison.

Average Weight Sleepers – 130 lbs- 230 lbs

The Amerisleep AS3 offers the most confort and assistance for middle-weight back sleepers. The AS2 is the better option for those who require extra support. If you are in between the AS4 or AS5 the weight categories, then you should consider the AS4. The Amerisleep AS1 is the most firm mattress for stomach sleepers within that weight class!

Heavyweight Sleepers – Over 230 lbs

The AS1 or AS2 of Amerisleep is ideal for people who weigh more and want to rest on their backs on a more firm mattress. The AS3, AS4, and AS5 might not be able to withstand their increased weight. The Amerisleep AS4 or AS5 will be suitable for heavier folks who want to lie on their backs. This Amerisleep AS5 is the better option for those who weigh more than 300 pounds. Even if they are planning to sleep with stomachs, the AS1 is their best option however, their size might render it unsuitable.

Lightweight Sleepers- Under 130 lbs

Light back sleepers require mattresses that aren’t overly rigid, since this can stop their hips from sinking fully to the floor. Their best bet is to buy any of the Amerisleep AS3 models or the Amerisleep AS4 (if they’re looking for something a bit softer). Its AS3, AS4, and AS5 are the best options for pressure relief for side sleepers because of its light weight and size, however the AS5’s additional features might not be required for those who sleep on their side. They’ll get the support they require on AS1 or AS2 as they sleep.

Amerisleep Mattress Performance


Let’s take a look at how Amerisleep mattresses do! Find out how they performed with regards to coolness, movement transfer, and edge support by reading on.

Sleeping Hot Or Cold

Our experience has shown that Amerisleep mattresses do not generate excessive heat when you sleep. Bio-Pur foam was created to keep the mattress cool, as we stated earlier. When you sleep in Amerisleep mattresses, it is important not to overheat as much as you may on other mattresses.

Mattresses made of latex and coils are great for keeping you cool in the evening if are suffering from excessive heat. Hybrid mattresses are ideal for sleepers who are hot since they’re more air-conditioned.

Motion Transfer

While they’re more responsive than the majority of mattresses Mattresses, they also have a low motion transfer coefficient. Due to the Bio-Pur foam’s motion isolation, if you sleep with a partner and you move around, it shouldn’t be disruptive to the mattress.

The thicker layers of Bio-Pur foam on both the AS3 and AS4 are ideal for couples looking for the most comfortable mattress.

Edge Support

Edge support varies among the Amerisleep mattresses. The mattresses that are more firm made us feel more at ease sitting or sleeping at the edges of them (the AS1 and AS2). We sense less edge support, especially while we are lying down, after upgrading to the softer variants.

Durability

All mattresses from Amerisleep are constructed of high-density material and are built to last. As a result, we estimate that the mattresses will last between seven and ten years in most.

Off-gassing

The Amerisleep mattresses exhibit some early off-gassing, but this is expected given that they are shipped in boxes. For an internet mattress, the scent of chemicals should disappear within 48 hours.

Noise

As we move around on the Amerisleep mattresses, they don’t produce any obvious sound. In the end, you won’t be able to hear your spouse’s movements around the house at late at night.

Sex

Mattresses made by Amerisleep are more responsive, which could make them ideal for sex, as per this review. If you choose the AS4 or AS5 mattresses, you might sink further and have difficulty getting your partner to move around.

Warranty Info

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

Amerisleep Hybrid Mattress Review


In addition to Amerisleep’s well-known all-foam mattresses, the company now makes hybrid options. The Amerisleep AS3 Hybrid version is actually a mix of foam mattresses. It’s a hybrid of the AS3 model, and we’re here to discuss our experience with the AS3 Hybrid model.

Support layers are the primary distinction between these two models. AS3 Hybrid has zoned pocketed coils, whilst AS3 all-foam is built on a polyfoam base. Even so, just like the AS3’s all foam counterpart it is also available in it’s AS3 Hybrid features Bio-Pur foam over the top.

Its AS3 Hybrid’s coils provide it with additional support than the AS3 mattress’s all foam counterpart. As a result, it may be a better option for those who are heavier and require additional support. The AS3 Hybrid mattress has a greater airflow due to the coils, which makes it a cooler mattress overall. If you’re looking for a price it is the AS3 Hybrid mattress is going to set you back about $200 more than AS3 foam mattress.

The Amerisleep foam mattresses are the ideal choice if you’re on a tight budget or in the lighter end in the range. In the event that you are heavier or require an item that’s more permeable, the Amerisleep Hybrid versions are the ideal choice.
