Amerisleep Mattress Firmness and Feel


The subject of firmness has been discussed a few times. There are many mattresses that can be described as firm. Amerisleep mattress stands out with its broad range of firmness options. Let’s talk about the degree of firmness of every Amerisleep mattress as well as how they feel.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress is firm in its unique way. The Amerisleep AS1 is more rigid than the average 8/10 mattress that starts on the firmer side of the spectrum. Its AS2 is the next-softest model; it is 7.5/10, which is still more difficult than the average. With scores of 6.5/10 it is the Amerisleep AS3 is right in the middle of the firmness range. This is because the Amerisleep AS4 and AS5 have the distinction of being the 2 softest versions in the following order. The AS4 is less than average, at 6/10, and the AS5 is softer-than-average at 5.5/10.

However, the firmness of these mattresses will be determined by your weight and height. On the other hand, they could feel firmer when you press deeper into the mattress and get to the support layers if are heavier. If you’re a lighter person, though it is possible that these mattresses are considerably more soft.

 

Sleeping On The Amerisleep Mattresses


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

Amerisleep AS1

AS1

Being one of the most firm mattresses in the Amerisleep series The AS1 could be too firm for back sleepers. The support is excellent however, there isn’t a comfort layer enough to allow our hips to be able to sink completely into it. We were disappointed. If you sleep on your back, need the hips of your back to slide in a good bit to ensure your spine remains in a neutral posture as you sleep.

When we sleep on our sides as we sleep, we feel a lot of stress on our shoulders and hips as a result of AS1. We’ll take a closer examine the more supple variants in a second and discover how they relieve tension.

The Amerisleep AS1 really shines while sleeping on our stomachs. Sleepers who lie on their stomachs need a mattress that provides support for their hips. If the hips aren’t properly support, their spine could be forced out of its 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 and AS1, we can enjoy a better balance of comfort and support while sleeping in a back position. Our hips are properly bowed, and the top foam layers are pressing into the lumbar area.

The AS2 isn’t firm enough to be used for sleeping on the side; we drive into the mattress and feel bunched up around our hips and shoulders. After a few nights, we could see this causing significant discomfort and pain.

We can feel a decent support beneath our hips stomach sleeping on the Amerisleep AS2. However, if you only sleep on your stomach, it is the Amerisleep AS1 will be the best way to go.

Amerisleep AS3

AS3

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

There is almost no stress on my shoulders or hips when I sleep on my back with AS3 AS3. The Bio-Pur foam actually cushions our joints, which is different from the previous experiences we had when using AS1 or AS2.

In our belly The Bio-Pur foam is doing us no favours. When it comes to pressure reduction, it’s amazing, but we’re not getting sufficient support for our hips.

Amerisleep AS4

AS4

We’re now in the realm of a soft mattress. Since AS4 is the AS4 mattress by Amerisleep is the second most flexible, we’re experiencing a loss of support when we lie in a back position. The lumbar support is weak and we’re sinking into the mattress a bit.

The Amerisleep AS4 mattress performs best when used on the side. It’s sinking in due to the huge four inches of bio-pur, and our hips and shoulders are hardly feeling any strain.

When it comes to stomach sleeping mattresses that are suitable for side sleep isn’t ideal. The Amerisleep AS5 is no exception, and it doesn’t give us the assistance we require.

Amerisleep AS5

Amerisleep Foundation King

There is a layer of Active Flex in the Amerisleep AS5, which is their most soft and extravagant model. In the end, we experience additional support for our heads and shoulders when we lie in our backs.

The AS5 is a good option for those who sleep on their sides since it is the most comfortable mattress. The weight of the world is absorbed as we sink into the soft comfort layers.

If you are sleeping on your stomach, the A5 does not offer enough support, regardless of the Active Flex foam. When we sleep in a back position, we like more the Amerisleep AS1 and AS2.

What Is the Feel of the Amerisleep Mattress?


The foam used in the majority of Amerisleep mattresses shares a similar feel , and it is soft and firm at same time. Although we may sink quite a little when we lie on these mattresses, we have no problem moving about at all. The Bio-Pur foam used in each of these five mattresses is different, and we sink into softer beds more.

Average Weight Sleepers – 130 lbs- 230 lbs

The Amerisleep AS3 provides the best convenience and comfort for middle-weight back sleepers. The AS2 is the better option for those who require extra support. If you fall in between the AS4 or AS5 the weight categories, then you should go for the AS4. The Amerisleep AS1 mattress is the most comfortable mattress designed for stomach sleepers in this weight range!

Heavyweight Sleepers – Over 230 lbs

AS1 or the AS1 also known as AS2 of Amerisleep is the ideal choice for those who are heavier and prefer to sleep on their backs on a mattress that is firmer. The AS3, AS4, and AS5 may not be strong enough to take their weight increase. The Amerisleep AS4 or AS5 will be suitable for those who weigh more and prefer to lie on their backs. It is the Amerisleep AS5 is the better option for people who weigh over 300 pounds. If they intend to stomach sleep, the AS1 is the best choice however their size could cause it to be insufficient.

Lightweight Sleepers- Under 130 lbs

Back sleepers who are light in weight require a mattress that isn’t too hard, because this will keep the hips of their backs sinking completely in the bed. Their best option would be to buy one of the two Amerisleep AS3 models or the Amerisleep AS4 (if they’re looking for something more supple). AS3, AS3, AS4, and AS5 are the best options for pressure relief for those who sleep on their sides because of its light weight, but the AS5’s additional features might not be required for them. They’ll get all the help they need on either AS1 or AS2 when they’re sleeping.

 

Amerisleep Mattress Construction


There are some commonalities between the Amerisleep mattresses, including the utilization of the identical materials. Regarding the comfort layers there are some significant variations.

Amerisleep AS1

There is a permeable covering on this Amerisleep AS1 mattress like it is on all Amerisleep mattresses. Bio-Pur Foam, a substance present at the top layer of every Amerisleep mattresses, covers that top 2″ of mattress’s comfort layer. A plant-based foam that is more breathable and flexible than traditional memory foam is the name we’re using for this new material. It’s more environmentally friendly than many mattress foams since it’s open-celled. Bio-Core foam, which measures 8.2 inches wide, gives an additional layer of support to the mattress.

Amerisleep Mattress Performance


Let’s look at how Amerisleep mattresses fare! Find out how they performed with regards to the cooling process, transfer of motion, and edge support. Read on.

Sleeping Hot Or Cold

In our experience, Amerisleep mattresses don’t cause excessive heat when sleeping. Bio-Pur foam was made for cooling the mattress, as we mentioned earlier. If you’re sleeping with Amerisleep mattresses, you should not overheat as much as you may with other mattresses.

Mattresses made of latex and coils are great for keeping you cool in the evening if have a major problem with overheating. Hybrid mattresses are ideal for those who sleep hot because they are more comfortable and breathable.

Motion Transfer

Although they’re more responsive than most, Amerisleep mattresses have a low motion transfer coefficient. As a result of the Bio-Pur foam’s motion isolation, if you sleep with someone else their movements shouldn’t cause disturbance to them.

The thicker Bio-Pur foam layers within the AS3 and AS4 make them ideal for couples seeking the greatest mattress.

Edge Support

Edge support varies among the Amerisleep mattresses. The mattresses that are more firm allowed us to feel more comfortable sleeping or sitting on the edge of them (the AS1 and AS2). We sense less edge support particularly when we’re lying down, after upgrading to the more soft models.

Durability

All mattresses from Amerisleep are constructed of high-density material and are built to last. In the end we predict that the mattress will last 7 to 10 years, at very least.

Off-gassing

The Amerisleep mattresses do show some initial off-gassing, but this is to be expected considering that they are shipped in the form of a box. If you purchase a mattress online that contains chemicals, the smell should dissipate within 48 hours.

Noise

As we move around on Amerisleep mattresses, they don’t produce any significant noise. As a result, you won’t hear your spouse’s movements through the house at evening.

Sex

Mattresses made by Amerisleep are more flexible, which could make them ideal for sex, according to this review. But, if you’re using the AS4 or AS5 mattresses, you might sink further and have difficulties 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 has now introduced hybrid models. Amerisleep’s AS3 Hybrid version is actually a hybrid version of its all foam AS3 model and we’re here to talk about our experience with the AS3 Hybrid model.

Support layers are the main difference between the two models. AS3 Hybrid has zoned pocketed coils, while AS3 all-foam is built on a polyfoam core. However, like the AS3’s all-foam counterpart it is also available in the AS3 Hybrid features Bio-Pur foam over the top.

Its AS3 Hybrid’s coils provide it with more support than the AS3 mattress’s all-foam counterpart. This means it could be a better option for those who are heavier and need additional support. It is also a better option for those who require additional support. AS3 Hybrid mattress has a higher ventilation because of the coils, which makes it a cooler mattress in general. In terms of cost it is it is the AS3 Hybrid mattress is going cost you around 200 dollars more expensive than AS3 foam mattress.

The Amerisleep foam mattresses are the most suitable choice when you’re on a strict budget or are in the lighter end on the scale. In the event that you’re heavier or want a mattress that is more permeable then the Amerisleep Hybrid versions are the best option.

 

Summary Amerisleep Foundation King


In general, I believe that the Amerisleep mattresses are excellent.

Many sleepers can pick an Amerisleep that works best for them because of the many options available.

The mattresses are extremely comfortable to the touch and offer great comfort and support at a reasonable cost.
