Amerisleep Mattress Firmness and Feel


The subject of firmness has been discussed a few times. The Amerisleep mattress stands out with its large range of firmness options. Let’s talk about the level of firmness for each Amerisleep mattress, and the way it is felt.

How Firm Are The Amerisleep Mattresses?

Each Amerisleep mattress is firm in its own unique way. The Amerisleep AS1 is a more rigid 8/10 mattress that starts on the firmer side of the scale. AS2 AS2 is the next softest model. It scores 7.5/10 however it is harder than usual. With a score of 6.5/10 The Amerisleep AS3 is right in the middle of the firmness range. The Amerisleep AS4 as well as the AS5 is the AS4 and AS5 are two of the softer models in the following order. The AS4 is softer-than-average at 6/10. The AS5 is less abrasive than average at 5.5/10.

However the firmness of these mattresses will be determined by the height and weight you carry. On one hand, these mattresses may appear more firm when you are able to press more deeply into the mattress and reach the support layers, if you are heavier. If you’re a lighter person, though, you may find the five mattresses substantially soft.

 

Sleeping On The Amerisleep Mattresses


I spent a lot of time in each of the five mattresses, trying the mattresses in different sleeping positions. As you can see, they differed in their performance!

Amerisleep AS1

AS1

Being one of the most firm mattresses of the Amerisleep series, the AS1 might be too hard for those who sleep on their backs. The support is great however, the comfort layer isn’t thick enough to allow our hips to fully sink into it. We were dissatisfied. When you lie on your back, you would like that your hips sink in for a bit in order to maintain your spine in a neutral posture as you rest.

If we lie on our side as we sleep, we feel lots of pressure on our shoulders as well as our hips because of the AS1. We’ll have a look at the soft variants in a second and see how they alleviate tension.

The Amerisleep AS1 really shines when you sleep on your stomachs. People who sleep on their stomachs should have a mattress that provides support for their hips. If the hips aren’t adequately secured, your spine could be pulled out of alignment. Amerisleep AS1 has adequate spinal support and this shouldn’t be an issue.

Amerisleep AS2

AS2

Since the AS2 is softer than the AS1, we get a better balance of comfort and support while sleeping with our backs. Our hips are properly bowed, and the top foam layers are pressing into the lumbar region.

The AS2 is still too firm for side sleeping as we push ourselves into the mattress and feel tangled in our shoulders and hips. After several nights, we could see this is causing significant discomfort and discomfort.

We can feel a decent support beneath our hips sleep on stomachs on Amerisleep AS2. If you prefer to sleep on your stomach then you’ll find that 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. Therefore, it’s no surprise it is that AS3 is one of our top options for back sleepers. The Bio-Pur foam layer on top provides a bit of contouring to our bodies while keeping us in place. It’s among the best pillows for sleepers with backaches in the Amerisleep types.

There isn’t much pressure on my shoulders and hips when I sleep on my side using AS3. AS3. The thicker layer of Bio-Pur foam is actually cushioning our joints, unlike our previous experience using AS1 and AS2.

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

Amerisleep AS4

AS4

We’re now in the realm of a mattress that’s soft. Since AS4 is the AS4 mattress is Amerisleep’s 2nd most supplemattress, we’re getting less support when sleeping on our backs. Lumbar support is not as strong and we’re sinking down the mattress slightly.

The Amerisleep AS4 mattress works best when used on the side. The mattress is sinking due to the huge 4 inches of Bio-Pur foam as well as our hips and shoulders are hardly feeling any strain.

When it comes to stomach sleeping mattresses that are good for side sleeping isn’t ideal. The Amerisleep AS5 mattress isn’t an exception and does not offer the support we need.

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep AS4 Vs Casper

There’s 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 head and shoulders when we lie on our backs.

The AS5 is an excellent choice for side sleepers because it is the softest mattress. The burden of the world disappears as we sink into the soft comfort layers.

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

What Is the Feel of the Amerisleep Mattress?


The foam that is used in the majority of Amerisleep mattresses is similar in feel , and it is firm and soft at the same time. Although we may sink a little when we lie on the mattresses, we experience no difficulty moving around at all. The Bio-Pur foam used in these five mattresses is different in thickness, and we sink more into the soft mattresses more. Look over our Amerisleep against Tuft and Needle comparison to see how they stack up against another responsive mattress. Check out the way Amerisleep and GhostBed perform against a mattress made of latex in our Amerisleep and GhostBed comparison.

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, but the AS2 is the best choice for those who need extra support. If you are in between both the AS4 and AS5 different weights 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

AS1 or the AS1 (or AS2 of Amerisleep is the ideal choice for people who weigh more and want to sleep on their backs on a firmer mattress. The AS3, AS4, and AS5 could not be strong enough to take 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 better option for those who weigh over 300 pounds. Even if they plan to sleep on their stomachs, 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 hard, because this will stop your hips from sinking fully into the mattress. Their best option would be to buy any of the Amerisleep AS3 models or the Amerisleep AS4 (if they want something more supple). Its AS3, AS4, and AS5 are the best options for pressure relief for side sleepers due to its lightweight and size, however the AS5’s additional features may not be necessary for them. They’ll get all the help they require from either AS1 or AS2 while they sleep.

Amerisleep Mattress Performance


Let’s take a look at how Amerisleep mattresses fare! Check out their performance in terms of cooling, motion transfer and edge support. Read on.

Sleeping Hot Or Cold

Based on our experience, Amerisleep mattresses don’t cause excessive heat when sleeping. The Bio-Pur foam is created so that the mattress remains cool as we stated earlier. If you are sleeping with Amerisleep mattresses, you should not overheat the way you would on other mattresses.

Latex and coil mattresses are great for keeping you cool during the night if you have a major problem with excessive heat. Hybrid mattresses are great for sleepers who are hot since they’re more comfortable and breathable.

Motion Transfer

While they’re more responsive than other mattresses Mattresses, they also are not as responsive to motion and have a lower coefficient. Because of Bio-Pur’s motion-isolation when you sleep with a partner, your movements should not cause disturbance to the mattress.

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

Edge Support

Edge support differs among Amerisleep mattresses. The mattresses that are more firm allowed us to feel more comfortable sleeping or sitting at the edges of them (the AS1 and AS2). We felt less edge support 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. As a result we believe that these mattresses will endure seven to ten years at minimum.

Off-gassing

The Amerisleep mattresses have some early off-gassing, but this is expected given that they are shipped in the form of a box. For a mattress purchased online the scent of chemicals should disappear within 48 hours.

Noise

If we sleep on the Amerisleep mattresses and sleep, they do not produce significant noise. This means that you won’t be able to hear your spouse’s movements through the house at night.

Sex

Mattresses made by Amerisleep are more flexible, which could make them suitable for sex, according to this review. If you choose an AS4 mattress or AS4 or AS5 mattresses, you might sink even deeper and have a more difficult time getting your partner to move 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 is now offering hybrid alternatives. Amerisleep’s AS3 Hybrid version is actually a hybrid of its all foam AS3 model and we’re here to share our experiences with it.

The support layers make up the primary distinction between these two models. AS3 Hybrid has zoned pocketed coils, whereas AS3 all-foam has a foundation polyfoam core. But, as with the AS3’s all-foam counterpart it is also available in AS3 Hybrid is also a polyfoam. AS3 Hybrid features Bio-Pur foam over the top.

Its AS3 Hybrid’s coils provide it with extra support over the AS3 mattress’s all-foam counterpart. This means it could be a better option for those who are heavier and need additional support. As a result, the AS3 Hybrid mattress has a greater airflow due to the coils. This makes it a cooler mattress overall. When it comes to cost it is the AS3 Hybrid mattress is going cost you around $200 more than AS3 All-Foam Mattress.

The Amerisleep all-foam mattresses are the best option for those on a tight budget or are on the lighter side of the spectrum. In the event that you are heavier or require an additional mattress that’s permeable and breathable, the Amerisleep hybrid models are the most suitable choice.
