Amerisleep Mattress Firmness and Feel


The subject of firmness has been discussed several times. There are many mattresses that can be described as firm. Amerisleep mattress is distinguished by its broad selection of firmness options. Let’s discuss the level of firmness for every Amerisleep mattress and how it feels.

How Firm Are Amerisleep Mattresses?

Each Amerisleep mattress is firm in its own unique way. Its Amerisleep AS1 is a more rigid mattress with an 8/10 rating that is on the firmer end of the scale. Its AS2 is the next softest model; it is 7.5/10 however it is heavier than average. With a score of 6.5/10, the Amerisleep AS3 is right in the middle of the firmness range. This is because the Amerisleep AS4 and AS5 are the two most soft versions following that. The AS4 is more comfortable than average at 6/10, and the AS5 is less abrasive than average at 5.5/10.

However the firmness of these mattresses will be dependent on the height and weight you carry. On the one hand, they could appear more firm when you press deeper into the mattress and reach the support layers if you are a heavier person. If you are a lighter person, though it is possible that these mattresses are considerably more soft.

 

Sleeping On The Amerisleep Mattresses


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

Amerisleep AS1

AS1

Being one of the most firm mattresses of 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 be able to sink completely into it. We were dissatisfied. On your back, you need that your hips sink in enough to keep your spine in a neutral position while you rest.

If we lie on our backs as we sleep, we feel a lot of pressure on our shoulders and hips due to the AS1. We’ll take a closer look at the soft variants in a second and see how they alleviate tension.

The Amerisleep AS1 is a shining model when we sleep on our stomachs. People who sleep on their stomachs should have mattresses that provide the hips with support. If the hips aren’t properly secured, your spine might be thrown out of position. Amerisleep AS1 provides adequate support for the spine, thus this shouldn’t be a concern.

Amerisleep AS2

AS2

Because the AS2 is softer than the AS1 which is why we have an improved 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 region.

The AS2 is still too firm for side sleepers; we drive into the mattress and feel tangled in our shoulders and hips. After some nights, we could see the cause of this discomfort and pain.

We can feel a decent support beneath our hips sleep on stomachs on Amerisleep AS2. If, however, you rest on your stomach then the Amerisleep AS1 will be the way to go.

Amerisleep AS3

AS3

A medium-firm mattress like one like the Amerisleep AS3 is ideal for back sleepers. It’s no surprise to find that the AS3 is one of our top choices for those who sleep on their backs. The Bio-Pur foam top layer provides a bit of contouring to our bodies while keeping us in the right position. It’s one of the greatest mattress for those who sleep on their backs, among the Amerisleep types.

There isn’t much pressure on my shoulders and hips when I sleep on my back with the AS3. This larger layer of Bio-Pur foam is actually cushioning our joints, unlike the previous experiences we had with AS1 as well as AS2.

In our bellies the Bio-Pur foam layer does us no good. When it comes to compression reduction it’s amazing however, we’re not getting enough support for our hips.

Amerisleep AS4

AS4

We’re currently on the verge of a soft mattress. Since AS4 is the AS4 mattress has been rated as Amerisleep’s second most supple, we are losing some support when we lie in a back position. The lumbar support is weak and we’re sinking into the mattress a bit.

It’s true that the Amerisleep AS4 mattress performs best when used on the side. We’re sinking into the mattress due to the huge 4-inch Bio-Pur foam and our shoulders and hips are hardly feeling any strain.

If you’re looking for a mattress that is suitable for stomach sleeping mattresses that are suitable for side sleep isn’t the ideal. The Amerisleep AS5 is no exception, and it doesn’t give us the assistance we require.

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep AS4 Vs Saatva

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

The AS5 is an excellent choice for side sleepers due to its soft mattress. The world’s weight disappears as we sink in the comfort of the layers.

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

What Is the Feel of the Amerisleep Mattress?


The foam used in all Amerisleep mattresses has a similar feel and is both soft and firm at the same at the same time. Even though we do sink quite slightly when we lay on the mattresses, we experience no difficulty moving around even. The Bio-Pur foam used in all five mattresses differs from one to the next, and we sink into the soft mattresses more. Take a look at our Amerisleep against Tuft and Needle comparison to find out how they compare against a different mattress that is responsive.

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 best choice for those who need extra support. If you’re between both the AS4 or AS5 weight ranges, then you should go for the AS4. The Amerisleep AS1 is the firmest mattress designed for stomach sleepers in that weight class!

Heavyweight Sleepers – Over 230 lbs

The AS1 or AS2 from Amerisleep is suitable for people who weigh more and want to sleep on their backs on a more firm mattress. As for the AS3, AS4, and AS5 may not be strong enough to take their heavier weight. They are the Amerisleep AS4 or AS5 will be suitable for those who weigh more and prefer to sleep on their sides. This Amerisleep AS5 is a superior option for those who weigh over 300 pounds. If they intend to sleep on their stomachs in the AS1 is their best option, but their size may cause it to be insufficient.

Lightweight Sleepers- Under 130 lbs

Back sleepers who are light in weight require a mattress that isn’t too firm, as this will stop the hips of their backs sinking completely into the mattress. 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). Its AS3, AS4, and AS5 should provide the most pressure relief for those who sleep on their sides because of its light weight, but the AS5’s additional features may not be necessary for these sleepers. They’ll receive all the assistance they need on either AS1 or AS2 while they sleep.

Bio-Pur Foam is a material that’s found at the top of all Amerisleep mattresses, makes up 2 inches on the uppermost layer of comfort. A plant-based foam that’s more breathable and flexible than conventional memory foam is what we’re calling this brand new material.

Amerisleep Mattress Performance


Let’s see how the Amerisleep mattresses perform! See how they did in terms of the cooling process, transfer of motion, and edge support by reading on.

Sleeping Hot Or Cold

Our experience has shown that Amerisleep mattresses do not cause excessive heat when you sleep. Bio-Pur foam was created so that the mattress remains cool as we stated earlier. When you sleep in Amerisleep mattresses, you should not overheat as much as you may on other mattresses.

Mattresses made of latex and coils can help keep you cool at night if you suffer from excessive heat. Hybrid mattresses are ideal for sleepers who are hot since they’re more comfortable and breathable.

Motion Transfer

While they’re more responsive than the majority of mattresses Mattresses, they also have a low motion transfer coefficient. Due to Bio-Pur’s motion isolation and motion isolation, if you are sleeping with someone else their movements shouldn’t be disruptive to them.

The thicker layers of Bio-Pur foam within the AS3 and AS4 are ideal for couples looking for the greatest mattress.

Edge Support

Edge support differs among Amerisleep mattresses. The firmer models made us feel more comfortable sitting or sleeping on their edges (the AS1 and AS2). We felt less edge support especially when lying down, when we upgrade to the softer variants.

Durability

All mattresses from Amerisleep are made from high-density materials and are built to last. Therefore we predict that these mattresses will endure seven to ten years at very least.

Off-gassing

The Amerisleep mattresses exhibit some early off-gassing. However, this is to be expected considering the fact that they’re delivered in a box. For an internet mattress that contains chemicals, the smell should dissipate within 48 hours.

Noise

When we roll around on our Amerisleep mattresses, they don’t produce any significant noise. This means that you won’t be able to listen to your partner’s movement throughout the house during the night.

Sex

Mattresses made by Amerisleep are more responsive, which could make them ideal for sex, as per this review. But, if you’re using an AS4 mattress or AS4 or AS5 mattress, you could sink deeper and experience a more difficult time moving your partner around.

Warranty Info

All Amerisleep mattresses include a 100-night 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 model is a hybrid version of its all foam AS3 model and we’re here to share our experiences with the AS3 Hybrid model.

Support layers are the main distinction between the two models. AS3 Hybrid has zoned pocketed coils, whilst AS3 all-foam has a foundation polyfoam core. But, as with the AS3’s all foam counterpart AS3 Hybrid, the AS3 Hybrid features Bio-Pur foam over the top.

The AS3 Hybrid’s coils give it additional support than the AS3 mattress’s all foam counterpart. Therefore, it may be a better option for people who weigh more and need additional support. The AS3 Hybrid mattress has a greater airflow due to the coils. This makes it a more comfortable mattress overall. In terms of cost it is this AS3 Hybrid mattress is going cost around $200 more than AS3 foam mattress.

The Amerisleep all-foam mattresses are the best option when you’re on a strict budget or at the lighter end of the spectrum. If you are heavier or require an additional mattress that’s permeable, the Amerisleep hybrid models are the most suitable choice.

Overall, I think the Amerisleep mattresses are fantastic.

Many sleepers can pick an Amerisleep which is suitable for them due to the wide variety of options.

The mattresses are extremely cool to the touch and they offer excellent comfort and support at a reasonable cost.
