Amerisleep Mattress Firmness And Feel


The topic of firmness has been mentioned a few times. There are many mattresses that can be described as firm. Amerisleep mattress stands out with its wide choice of firmness choices. Let’s discuss the degree of firmness of every Amerisleep mattress as well as how they feel.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress is unique in its firmness way. Its Amerisleep AS1 is a stiffer-than-average 8/10 mattress that starts on the more firm side of the scale. Its AS2 is the next softest model; it is 7.5/10 however it is more difficult than the average. With scores of 6.5/10 it is the Amerisleep AS3 is right in the middle of the range of firmness. This is because the Amerisleep AS4 as well as the AS5 are the two softest variants in the following order. The AS4 is softer-than-average at 6/10. The AS5 is less abrasive than average at 5.5/10.

Having said that, the mattress’s firmness will be determined by the height and weight you carry. On one hand, these mattresses may feel firmer when you push deeper into the mattress and reach the support layers if are heavier. If you are an overweight person, you may find that these mattresses are substantially soft.

 

Sleeping On The Amerisleep Mattresses


I spent a good amount of time on each of the five mattresses, testing their sleeping positions in various ways. You can clearly see that each differed in their performance!

Amerisleep AS1

AS1

As one of the firmest mattresses within the Amerisleep series The AS1 may be too firm for back sleepers. The support is great however it’s comfort layer doesn’t seem thick enough to let our hips sink into it completely. We were dissatisfied. On your back, you would like your hips to sink in a good bit to ensure your spine remains in a neutral position as you rest.

When we sleep on our sides as we sleep, we feel a lot of pressure on our shoulders and hips as a result of AS1. We’ll examine the more supple versions in the next paragraph and find out how they ease stress.

The Amerisleep AS1 really shines while we sleep on our stomachs. Sleepers who lie on their stomachs need mattresses that provide support for their hips. If the hips aren’t adequately support, their spine could be forced out of its position. Amerisleep AS1 offers adequate spinal support, thus this shouldn’t be an issue.

Amerisleep AS2

AS2

Because the AS2 is softer than the AS1 which is why we have a better balance of support and comfort while we sleep in a back position. The hips are correctly bent, and the top foam layers are pushing up into the lumbar region.

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

We can feel some decent support beneath our hips stomach sleeping on the Amerisleep AS2. If, however, you sleep on your stomach then you’ll find that the Amerisleep AS1 will be the best way to go.

Amerisleep AS3

AS3

A mattress that is medium-firm like one like the Amerisleep AS3 is ideal for back sleepers. Therefore, it’s no surprise that the AS3 is one of our top choices for back sleepers. The Bio-Pur foam top layer 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 in the Amerisleep types.

There is virtually no tension on my shoulders or hips when I sleep on my side using AS3. AS3. This larger layer of Bio-Pur foam actually cushions our joints, unlike our previous experience with AS1 and AS2.

In our belly The Bio-Pur foam is doing us no favours. When it comes to the reduction of pressure, this is fantastic but we’re not receiving adequate support for our hips.

Amerisleep AS4

AS4

We’re currently on the verge of a mattress that’s soft. Since it’s the AS4 mattress is Amerisleep’s second most supple, we are experiencing a loss of support when sleeping on our backs. The lumbar support is weak and we’re sinking down the mattress a bit.

It’s true that the Amerisleep AS4 mattress performs best when it is placed on its side. The mattress is sinking thanks to a huge four inches of bio-pur foam as well as our hips and shoulders aren’t feeling much strain.

If you’re looking for a mattress that is suitable for stomach sleeping, a mattress that is suitable for side sleep isn’t ideal. The Amerisleep AS5 is not an exception and does not give us the assistance that we require.

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep Flat Base

There’s a layer Active Flex in the Amerisleep AS5 which is their most soft and luxurious model. This means that we get more support for our necks and shoulders while lying on our backs.

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

If you are sleeping on your stomach, the A5 does not offer enough support, even with its Active Flex foam. When we sleep on our backs, we like more the Amerisleep AS1 and AS2.

What Is the Feel of the Amerisleep Mattress?


The foam that is used in all Amerisleep mattresses is similar in feel and is both soft and firm at same simultaneously. Even though we do sink a little when we lie on these mattresses, we have no difficulty moving around in any way. The Bio-Pur foam that is used in these five mattresses varies from one to the next, and we sink into the softer beds more.

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. The AS2 is the better option for those who require more support. If you fall between the AS4 as well as AS5 weight ranges, you ought to opt for the AS4. The Amerisleep AS1 is the firmest mattress for stomach sleepers within that weight class!

Heavyweight Sleepers – Over 230 lbs

It is the AS1 or AS2 of Amerisleep is ideal for heavier persons who prefer to sleep on their backs on a firmer mattress. It is possible that the AS3, AS4, and AS5 could not be able to withstand their heavier weight. They are the Amerisleep AS4 or AS5 is recommended for those who weigh more and prefer to lie on their backs. It is the Amerisleep AS5 is a superior option for those who weigh more than 300 pounds. Even if they plan to stomach sleep, the AS1 is the best choice however, their size might make it insufficient.

Lightweight Sleepers- Under 130 lbs

Lightweight back sleepers need an appropriate mattress that isn’t too hard, because this will keep their hips from sinking fully in the bed. Their best bet is to purchase either of two Amerisleep AS3 models or the Amerisleep AS4 (if they prefer something that is softer). The AS3, AS4, and AS5 will provide the best pressure relief for side sleepers due to its lightweight and size, however the AS5’s additional features might not be needed for these sleepers. They’ll get the support they require on AS1 or AS2 when they’re sleeping.

Amerisleep Mattress Performance


Let’s see how the Amerisleep mattresses fare! See how they did in terms of coolness, movement transfer and edge support by reading on.

Sleeping Hot Or Cold

Based on our experience, Amerisleep mattresses do not cause excessive heat when sleeping. Bio-Pur foam was designed for cooling the mattress, which we have mentioned earlier. If you are sleeping on Amerisleep mattresses, you shouldn’t overheat as much as you may with other mattresses.

Mattresses made of latex and coils can help keep you cool in the evening if are suffering from overheating. Hybrid mattresses are ideal for sleepers who are hot since they are more air-conditioned.

Motion Transfer

While 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 when you sleep with a partner, your movements should not cause disturbance to them.

The more dense Bio-Pur foam layers that are within the AS3 and AS4 make them perfect for couples looking for the greatest mattress.

Edge Support

Edge support is different among Amerisleep mattresses. The more firm models let us feel more comfortable sitting or sleeping on their edges (the AS1 and AS2). We feel less support for the edges particularly when we’re lying down, when we upgrade to the more soft models.

Durability

All mattresses from Amerisleep are constructed of high-density material and are constructed to last. Therefore, we estimate that the mattresses will last 7 to 10 years, at minimum.

Off-gassing

The Amerisleep mattresses exhibit some early off-gassing, but this is normal given the fact that they’re delivered in a box. For an internet mattress the scent of chemicals should dissipate within 48 hours.

Noise

When we roll around on Amerisleep mattresses, they don’t produce any obvious sound. This means that you won’t hear your spouse’s movements through the house at night.

Sex

Mattresses made by Amerisleep are more responsive, which could make them ideal for sex, according to this review. However, if you use the AS4 or AS5 mattresses, you might 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


In addition to Amerisleep’s well-known all-foam mattresses, the company has now introduced hybrid models. Amerisleep’s AS3 Hybrid product is an mix of its all foam AS3 model, and we’re here to talk about our experience with it.

Layers of support are the main distinction between the two models. AS3 Hybrid has zoned pocketed coils, while AS3 all-foam has a foundation polyfoam base. But, as with the AS3’s all-foam counterpart AS3 Hybrid, the AS3 Hybrid features Bio-Pur foam as the top layer.

Its AS3 Hybrid’s coils provide it with extra support over the AS3 mattress’s all foam counterpart. As a result, 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 better ventilation due to the coils, making it a more comfortable mattress overall. If you’re looking for a cost 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 best option for those on a tight budget or are in the lighter end on the scale. In the event that you’re heavier or want an item that’s more permeable and breathable, the Amerisleep Hybrid versions are the best option.

 

Summary Amerisleep Flat Base


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

So many sleepers can choose an Amerisleep that works best for them due to the many options available.

The mattresses are really cool to the touch, and they offer excellent support and comfort for the price.
