Amerisleep Mattress Firmness and Feel


The subject of firmness has been discussed a few times. It is the Amerisleep mattress is distinguished by its large choice of firmness choices. Let’s discuss the level of degree of firmness of every Amerisleep mattress, and the way it is felt.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress is firm in its own unique way. For instance, the Amerisleep AS1 is more rigid than the average mattress with an 8/10 rating that is on the more firm side of the spectrum. AS2 AS2 is the second softest model; it is 7.5/10 but is more difficult than the average. With an average of 6.5/10 The Amerisleep AS3 is right in the middle of the range of firmness. The Amerisleep AS4 as well as the AS5 are the two softest versions in the following order. The AS4 is more comfortable than average at 6/10. The AS5 is less abrasive than average at 5.5/10.

However, the firmness of these mattresses will be dependent on your weight and height. On one side, they may feel firmer when you push deeper into the mattress and get to the support layers, if you are heavier. If you’re heavier, however you might find 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, testing the mattresses in different sleeping positions. As you can see, each performed differently!

Amerisleep AS1

AS1

As one of the firmest mattresses of the Amerisleep series, the AS1 could be too firm for those who sleep on their backs. The support is great however the comfort layer isn’t thick enough to allow our hips to sink into it completely. We were dissatisfied. When you lie on your back, you would like that your hips sink enough to ensure your spine remains in a neutral position as you rest.

If we lie on our sides as we sleep, we feel a lot of pressure on our shoulders as well as our hips because of the AS1. We’ll examine the more supple versions in the next paragraph and discover how they relieve stress.

The Amerisleep AS1 is a shining model when sleeping on our stomachs. People who sleep on their stomachs require an appropriate mattress that offers support for their hips. When the hips are not correctly secured, your spine may be thrown out of position. Amerisleep AS1 offers adequate spinal support and this shouldn’t be an issue.

Amerisleep AS2

AS2

Because the AS2 is less abrasive than the AS1, we get more comfort and support when we sleep on our backs. The hips are correctly bent and the foam layers are pushing up into the lumbar region.

The AS2 isn’t firm enough for side sleeping as we push ourselves into the mattress, and we feel like it is coiled over our hips and shoulders. After a few nights, we can see this is causing significant discomfort and pain.

There is a bit of 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 is the best option 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 that the AS3 is among our top options for those who sleep on their backs. The Bio-Pur foam top layer gives some contouring for our contours while also holding us in place. It’s among the best mattress for those who sleep on their backs among the Amerisleep varieties.

There is virtually no stress on my shoulders or hips when I lay on my back with AS3 AS3. This larger layer of Bio-Pur foam actually cushions our joints, unlike the previous experiences we had with AS1 and AS2.

In our belly The Bio-Pur foam isn’t doing us any favors. In terms of the reduction of pressure, this is incredible, but we’re not getting enough support for our hips.

Amerisleep AS4

AS4

We’re currently on the verge of a mattress that is soft. Since it’s the AS4 mattress by Amerisleep is the second most flexible, we’re getting less support when we lie on our backs. Lumbar support is lacking and we’re sinking down the mattress a little.

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 4 inches of Bio-Pur, and our hips and shoulders aren’t feeling much strain.

When it comes to stomach sleeping mattresses that are suitable for side sleep is not the best choice. The Amerisleep AS5 is no exception and does not provide us with the help that we require.

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep AS3 Split King

There is a layer of Active Flex in the Amerisleep AS5, which is their softest and extravagant model. This means that we experience additional support for our necks and shoulders while lying on our backs.

The AS5 is a great choice for side sleepers because it is the softest mattress. The world’s weight disappears as we sink in the comfort of the layers.

If you are sleeping on your stomach, the A5 does not provide enough support even with it’s Active Flex foam. When we sleep on our backs, we prefer 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 is similar in feel and is both firm and soft at the same time. Even though we do sink in the middle when lying on the mattresses, we experience no problem moving about in any way. The Bio-Pur foam utilized in these five mattresses differs from one to the next, and we sink into the mattress that is softer. Take a look at our Amerisleep comparison against Tuft and Needle comparison to check out how they compare against a different mattress that is responsive.

Average Weight Sleepers – 130 lbs- 230 lbs

The Amerisleep AS3 offers the most convenience and comfort for middle-weight back sleepers. The AS2 is the best choice for those who require more support. If you are in between those between the AS4 or AS5 different weights you should go for the AS4. The Amerisleep AS1 mattress is the most comfortable mattress for stomach sleepers within the AS4 and AS5 weight categories!

Heavyweight Sleepers – Over 230 lbs

The AS1 (or AS2 of Amerisleep is the ideal choice for people who weigh more and want to lie on their backs and sleep on a mattress that is firmer. The AS3, AS4, and AS5 may not be able to handle their heavier weight. It is possible that the Amerisleep AS4 or AS5 will be suitable for people who are heavier and want to lie on their backs. It is the Amerisleep AS5 is a superior choice for those who weigh more than 300 pounds. Even if they plan to stomach sleep in the AS1 is the best choice however their size could make it insufficient.

Lightweight Sleepers- Under 130 lbs

Light back sleepers require an appropriate mattress that isn’t too firm, as this will prevent your hips from sinking fully into the mattress. Their best bet is to choose any of the Amerisleep AS3 models or the Amerisleep AS4 (if they prefer something a bit softer). The AS3, AS4, and AS5 should provide the most pressure relief for sleepers on the side due to its lightweight, but the AS5’s additional features might not be required for them. They’ll receive all the assistance they require on AS1 or AS2 while they sleep.

 

Amerisleep Mattress Construction


There are certain similarities in these and Amerisleep mattresses, for instance the utilization of the same materials. Regarding the comfort layers, though there are some noticeable variations.

Amerisleep AS1

Bio-Pur Foam is a material that’s found on the top of all Amerisleep mattresses, is that top 2″ of mattress’s comfort layer. A plant-based foam that’s more breathable and flexible than conventional memory foam is what we’re calling this innovative material. It’s more environmentally friendly than many mattress foams because it’s open-celled. Bio-Core foam, which measures eight inches in thickness, gives an additional layer of support to the mattress.

Amerisleep Mattress Performance


Let’s see how the Amerisleep mattresses do! Check out their performance with regards to cooling, motion transfer and edge support. Read on.

Sleeping Hot Or Cold

Our experience has shown that Amerisleep mattresses do not generate excessive heat when sleeping. Bio-Pur foam is specifically made so that the mattress remains cool as we stated earlier. If you are sleeping on Amerisleep mattresses, it is important not to overheat as much as you may on other mattresses.

Latex and coil mattresses are great for keeping you cool at night if you are suffering from 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 the majority of mattresses, Amerisleep mattresses have a lower motion transfer coefficient. Because of Bio-Pur’s motion-isolation, if you sleep with a partner their movements shouldn’t cause disturbance to the mattress.

The more dense Bio-Pur foam layers that are in AS3 and AS3 and AS4 make them ideal for couples who want the best mattress.

Edge Support

Edge support differs among Amerisleep mattresses. The firmer models allowed us to 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 soft versions.

Durability

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

Off-gassing

The Amerisleep mattresses do show some initial off-gassing, but this is expected given the fact that they’re delivered in a box. If you purchase a mattress online that contains chemicals, the smell should disappear within 48 hours.

Noise

When we roll around on our Amerisleep mattresses, they don’t produce any significant noise. In the end, you won’t listen to your partner’s movement around the house at late at night.

Sex

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

Warranty Info

All Amerisleep mattresses are covered by a 100-night trial period and a 20-year warranty.

Amerisleep Hybrid Mattress Review


In addition to Amerisleep’s popular all-foam mattresses, the company 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 share our experiences with it.

Layers of support are the key distinction between the two models. AS3 Hybrid has zoned pocketed coils, whilst AS3 all-foam has a foundation polyfoam base. However, like the AS3’s all foam counterpart AS3 Hybrid, 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 version. As a result, it’s a good option for people who weigh more and require additional support. The AS3 Hybrid mattress has a higher ventilation because of the coils, making it a cooler mattress in general. When it comes to cost it is the AS3 Hybrid mattress is going to set you back about $200 more than the AS3 all-foam mattress.

The Amerisleep foam mattresses are the best option for those on a tight budget or are at the lighter end of the spectrum. In the event that you’re heavier or need a mattress that is more permeable then the Amerisleep Hybrid versions are the most suitable choice.

 

Summary Amerisleep AS3 Split King


Overall, I think the Amerisleep mattresses are excellent.

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

The mattresses are cool to the touch and they offer excellent comfort and support for the cost.
