Amerisleep Mattress Firmness And Feel


The subject of firmness has been discussed at least a couple of times. The Amerisleep mattress is distinguished by its large range of firmness options. Let’s discuss the level of level of firmness for every Amerisleep mattress and how it feels.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress is firm in its own unique 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. AS2 AS2 is the second softest model. It scores 7.5/10 but is harder than usual. With an average of 6.5/10 The Amerisleep AS3 is right in the middle of the firmness range. It is the Amerisleep AS4 and AS5 have the distinction of being the 2 softest variants following that. The AS4 is less than average, at 6/10, while the AS5 is less abrasive than average at 5.5/10.

However the quality of these mattresses will be determined by the height and weight you carry. On one side, they may feel firmer when you are able to press more deeply into the mattress, and then reach the support layers if are a heavier person. If you are heavier, however it is possible that these five mattresses are considerably soft.

 

Sleeping On The Amerisleep Mattresses


I spent a significant amount of time on all five mattresses, trying the mattresses in different sleeping positions. You can clearly see that they performed differently!

Amerisleep AS1

AS1

As one of the more firm mattresses in the Amerisleep series, the AS1 may be too firm for back sleepers. The support is great however, there isn’t a comfort layer enough to allow our hips to be able to sink completely into it. We were disappointed. On your back, you need the hips of your back to slide a good bit to maintain your spine in a neutral position while you rest.

If we lie on our side, we feel lots of stress on our shoulders and hips due to the AS1. We’ll have a examine the more supple versions in the next paragraph and find out how they ease tension.

The Amerisleep AS1 really shines while we sleep on our stomachs. People who sleep on their stomachs require a mattress that provides the hips with support. If the hips aren’t adequately supported, the spine might be forced out of its position. Amerisleep AS1 offers adequate spinal support and this shouldn’t be an issue.

Amerisleep AS2

AS2

Since the AS2 is less abrasive than the AS1 and AS1, we can enjoy a better balance of comfort and support when we sleep with our backs. Our hips are properly bowed and the top foam layers are pressing up into the lumbar region.

The AS2 isn’t firm enough for side sleepers as we push ourselves into the mattress and feel bunched in our shoulders and hips. After a few nights, we could see this is causing significant discomfort and pain.

We can feel some decent support beneath our hips stomach sleeping on the Amerisleep AS2. However, if you only sleep on your stomach and you do not want to sleep on your stomach, it is the Amerisleep AS1 is the way to go.

Amerisleep AS3

AS3

A medium-firm mattress like that of the Amerisleep AS3 is ideal for back sleepers. As a result, it’s no surprise to find that the AS3 is among our top picks for those who sleep on their backs. The Bio-Pur foam layer on top provides a bit of 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 tension on my shoulders or hips when I lay on my side using AS3 AS3. The thicker layer of Bio-Pur foam actually cushions our joints, which is different from our previous experience using AS1 or AS2.

In our belly the Bio-Pur foam layer does us no good. For pressure reduction, it’s fantastic however, we’re not getting adequate support for our hips.

Amerisleep AS4

AS4

We’re currently on the verge of a mattress that is soft. Since the AS4 mattress by Amerisleep is the 2nd most flexible, we’re getting less support when we sleep with our backs. Lumbar support is not as strong and we’re sinking down the mattress slightly.

The Amerisleep AS4 mattress performs best when placed on its side. The mattress is sinking due to a massive four inches of bio-pur foam 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 is not the best choice. The Amerisleep AS5 is no exception, and it doesn’t provide us with the help we require.

Amerisleep AS5

Amerisleep AS4 Mattress Review

There is a layer of Active Flex in the Amerisleep AS5 which is their most soft and extravagant model. This means that we get more support for our heads and shoulders as we lay upon our backs.

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

For stomach sleepers The A5 mattress does not provide enough support, even when using the Active Flex foam. If we are sleeping with our backs on the ground, we prefer 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 texture and feels soft and firm at same simultaneously. Although we may sink slightly when we lay on these mattresses, we’re having no problem moving about in any way. The Bio-Pur foam utilized in all five mattresses differs from one to the next, and we sink into the softer beds more.

Average Weight Sleepers – 130 lbs- 230 lbs

The Amerisleep AS3 offers the most comfort and support for average-weight back sleepers. However, the AS2 is the best choice for those who need extra support. If you fall between the AS4 as well as AS5 weight ranges, you should consider 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 from Amerisleep is ideal for those who are heavier and prefer to rest on their backs on a more firm mattress. As for the AS3, AS4, and AS5 might not be able to handle their increased weight. They are the Amerisleep AS4 and AS5 should 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. If they intend to stomach sleep, the AS1 is their best option however, their size might render it unsuitable.

Lightweight Sleepers- Under 130 lbs

Light back sleepers require a mattress that isn’t too rigid, since this can stop your hips from sinking completely to the floor. Their best option would be to buy either of 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 due to its lightweight and size, however the AS5’s additional features may not be necessary for these sleepers. They’ll get all the help they need on either AS1 or AS2 as they sleep.

 

Amerisleep Mattress Construction

Amerisleep AS1

Bio-Pur Foam is a material that’s found on the top of the majority of Amerisleep mattresses, is the top two inches of the mattress’s comfort layer. A plant-based, breathable foam that’s more comfortable and flexible than traditional memory foam is what we’re calling this innovative material. It’s more environmentally friendly than other mattress foams because it’s open-celled. Bio-Core foam, which is eight inches in thickness, provides extra support for mattresses.

Amerisleep Mattress Performance


Let’s look at how Amerisleep mattresses perform! Find out how they performed in terms of cooling, motion transfer, and edge support. Read on.

Sleeping Hot Or Cold

In our experience, Amerisleep mattresses don’t cause excessive heat while sleeping. The Bio-Pur foam is designed for cooling the mattress, as we stated earlier. When you sleep in Amerisleep mattresses, you should not overheat as much as you may on other mattresses.

The coil and latex mattresses are great for keeping you cool in the evening if suffer from excessive heat. Hybrid mattresses are great for those who sleep hot because they’re more air-conditioned.

Motion Transfer

Even though they are more responsive than other mattresses Mattresses, they also are not as responsive to motion and have a lower coefficient. Due to the Bio-Pur foam’s motion isolation, if you sleep with a partner and you move around, it shouldn’t cause disturbance to the mattress.

The thicker layers of Bio-Pur foam within the AS3 and AS4 make them ideal 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 sleeping or sitting 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 soft versions.

Durability

All of Amerisleep’s mattresses are made from high-density materials and are constructed to last. In the end we predict that these mattresses will endure 7 to 10 years, at the very least.

Off-gassing

The Amerisleep mattresses exhibit some early off-gassing. However, this is expected given the fact that they’re shipped in a box. If you purchase a mattress online, the scent of chemicals should disappear within 48 hours.

Noise

If we sleep on the Amerisleep mattresses, they don’t produce any noticeable noise. In the end, you won’t be able to listen to your partner’s movement around the house at night.

Sex

Mattresses made by Amerisleep are more flexible, which could make them ideal for sex, according to this review. But, if you’re using AS4 or the AS4 or AS5 mattress, you could sink even deeper 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


In addition to Amerisleep’s popular all-foam mattresses is now offering hybrid alternatives. The Amerisleep AS3 Hybrid product is an hybrid version of the all-foam AS3 model and we’re here to share our experiences with it.

Support layers are the primary distinction between the two models. AS3 Hybrid has zoned pocketed coils, whereas AS3 all-foam features a foundation polyfoam core. However, like the AS3’s all foam counterpart, the AS3 Hybrid features Bio-Pur foam as the top layer.

Its AS3 Hybrid’s coils offer it extra support over the AS3 mattress’s all-foam version. Therefore, it’s a good option for people who weigh more 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, making it a cooler mattress in general. If you’re looking for a price the AS3 Hybrid mattress is going to set you back about $200 more than AS3 All-Foam Mattress.

The Amerisleep foam mattresses are the most suitable choice when you’re on a strict budget or if you’re in the lighter end on the scale. If you’re heavier or want an item that’s more permeable, the Amerisleep hybrid models are the most suitable choice.

 

Summary Amerisleep AS4 Mattress Review


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

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

The mattresses are cool to the touch and offer great comfort and support for the price.
