Amerisleep Mattress Firmness And Feel


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

How Firm Are Amerisleep Mattresses?

Every Amerisleep mattress is firm in its unique way. The Amerisleep AS1 is more rigid than the average 8/10 mattress that starts on the firmer 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 an average of 6.5/10, the Amerisleep AS3 is right in the middle of the firmness range. It is the Amerisleep AS4 as well as the AS5 have the distinction of being the 2 most soft variants in the following order. The AS4 is less than average, at 6/10, and the AS5 is more comfortable than average at 5.5/10.

However, the quality of these mattresses will be determined by the height and weight you carry. On the one hand, these mattresses may seem more firm if you are able to press more deeply into the mattress, and then reach the support layers if are a heavier person. If you’re heavier, however you might find that these mattresses are substantially more soft.

 

Sleeping On The Amerisleep Mattresses


I spent a good amount of time on each of the five mattresses, evaluating them in various sleeping positions. It is evident that each performed differently!

Amerisleep AS1

AS1

Being one of the most firm mattresses in the Amerisleep series The AS1 could be too firm for back sleepers. Its support is fantastic however there isn’t a comfort layer thick enough for our hips to be able to sink completely into it. We were dissatisfied. When you lie on your back, you would like that your hips sink a good bit to ensure your spine remains in a neutral posture as you sleep.

If we lie on our backs, we feel the pressure on our shoulders as well as our hips as a result of AS1. We’ll have a look at the softer variations in the coming moments and find out how they ease stress.

The Amerisleep AS1 really shines when you sleep on your stomachs. Those who sleep on their stomachs require a mattress that provides the hips with support. If your hips aren’t correctly support, their spine may be thrown out of position. Amerisleep AS1 provides adequate support for the spine and this shouldn’t be an issue.

Amerisleep AS2

AS2

Because the AS2 is less abrasive 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 bent and the top foam layers are pressing into the lumbar region.

The AS2 isn’t firm enough to be used for sleeping on the side; we drive into the mattress and feel tangled over our shoulders and hips. After some nights, we can see this causing significant discomfort and the pain.

We can feel a decent support beneath our hips stomach sleeping on the Amerisleep AS2. If, however, you sleep on your stomach then the Amerisleep AS1 mattress is your 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 not a surprise it is that AS3 is one of our top choices for back sleepers. The Bio-Pur foam layer on top offers a little contouring to our contours while also holding us in the right position. It’s among the top pillows for sleepers with backaches in the Amerisleep kinds.

There is virtually no stress on my shoulders or hips when I sleep on my back with the AS3. The thicker layer of Bio-Pur foam is actually cushioning our joints, which is different from the previous experiences we had using AS1 or AS2.

In our belly the Bio-Pur foam layer is doing us no favours. In terms of pressure reduction, it’s amazing but we’re not receiving enough support for our hips.

Amerisleep AS4

AS4

We’re now in the realm of a mattress that is soft. Since AS4 is the AS4 mattress is Amerisleep’s second most supple, we are experiencing a loss of support when we lie on our backs. The lumbar support is weak and we’re sinking into the mattress slightly.

The Amerisleep AS4 mattress performs best when placed on its side. It’s sinking in due to a massive 4 inches of Bio-Pur, and our hips and shoulders are hardly feeling any strain.

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

SHOP AMERISLEEP

 

Amerisleep AS5

Amerisleep AS4

There is a layer of Active Flex in the Amerisleep AS5 which is their softest and extravagant model. In the end, we get more support for our heads and shoulders when we lie upon our backs.

The AS5 is a good choice for people who prefer sleeping on their side since it is the most comfortable mattress. The world’s weight fades away as we snuggle to the soft comfort layers.

If you are sleeping on your stomach The A5 doesn’t offer enough support, even with the 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 shares a similar feel , and it is soft and firm at the same time. Even though we do sink quite slightly when we lay on these mattresses, we have no trouble moving around even. The Bio-Pur foam used in all five mattresses varies from one to the next, and we sink into soft mattresses more. Check out our Amerisleep comparison against Tuft and Needle comparison to find out how they compare against another mattress that responds. See how Amerisleep and GhostBed perform against a mattress made of latex in our Amerisleep vs GhostBed comparison.

Average Weight Sleepers – 130 lbs- 230 lbs

The Amerisleep AS3 provides the best confort and assistance for the average-weight back sleepers. However, the AS2 is the better option for those who require extra support. If you’re between the AS4 or AS5 weight ranges, you should consider the AS4. The Amerisleep AS1 mattress is the most comfortable mattress for stomach sleepers within this weight range!

Heavyweight Sleepers – Over 230 lbs

It is the AS1 or AS2 of Amerisleep is ideal for people who weigh more and want to sleep on their backs on a more firm mattress. It is possible that the AS3, AS4, and AS5 could not be strong enough to take their heavier weight. They are the Amerisleep AS4 and AS5 should be suitable for people who are heavier and want to sleep on their sides. This Amerisleep AS5 is the better option for those who weigh more than 300 pounds. Even if they are planning to stomach sleep, the AS1 is the best choice, but their size may cause it to be insufficient.

Lightweight Sleepers- Under 130 lbs

Back sleepers who are light in weight require mattresses that aren’t overly hard, because this will keep their hips from sinking to the floor. Their best option would be to choose any of the Amerisleep AS3 models or the Amerisleep AS4 (if they want something a bit softer). Its AS3, AS4, and AS5 are the best options for pressure relief for sleepers on the side because of its light weight however, the AS5’s extra features may not be necessary for these sleepers. They’ll receive all the assistance they require from either AS1 or AS2 while they sleep.

 

Amerisleep Mattress Construction


There are certain similarities among these and Amerisleep mattresses, such as the utilization of the identical materials. Regarding the comfort layers there are some noticeable variances.

Amerisleep AS1

amerisleep-as1-construction

There is a permeable covering that covers the Amerisleep AS1 mattress, like there is on all the Amerisleep mattresses. Bio-Pur Foam is a material that’s found on the top of all Amerisleep mattresses, covers that top 2″ of 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 greener than many mattress foams because it’s open-celled. Bio-Core foam, which measures 8.2 inches wide, gives additional support for the mattress.

Amerisleep AS2

In terms of size in terms of height, it is taller than the Amerisleep AS2 measures in at 12 inches, much like the other models. As with the AS1 it also has 2 inches of bio-pur top of it. The 3″ of HIVE transition layer is also in the bottom layer to give extra support and comfort different areas of the bed. Bio-Core foam is used in the 7-inch support layer.

Amerisleep AS3

It has three” thick layer of Bio-Pur foam on the top of the Amerisleep’s comfort layer, and the mattress is 12″ tall. In addition to the AS3, you get an inch more. This HIVE layers are 2 inches thick instead of 3” thick. A 7-inch Bio-Core foam layer completes that support layer.

When compared to Amerisleep AS3, the Bio-Pur foam top layer is much thicker (it is 4” in thickness!). Only 1” of Bio-Pur foam, the HIVE transition foam and 7 inches of Bio-Core foam make up the bottom layer of the mattress.

Amerisleep AS5

The Amerisleep AS5 mattress has an extremely thick 14-inch cover and you’ll know the name. It’s likely to be similar to the rest of the mattresses in the store. It is made of Bio-Pur and is sandwiched with layers of distinct AS5 foam. It is soft and springy. Active Flex is used in the making of this 2 inch piece. All Amerisleep mattresses have a 7-inch base layer of Bio-Core foam.

Amerisleep Mattress Performance


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

Sleeping Hot Or Cold

In our experience, Amerisleep mattresses do not generate excessive heat when sleeping. Bio-Pur foam is specifically created so that the mattress remains cool as we mentioned earlier. If you are sleeping in Amerisleep mattresses, you shouldn’t overheat like you do on other mattresses.

Latex and coil mattresses are great for keeping you cool at night if you are suffering from overheating. Hybrid mattresses are great for those who sleep hot because they are more comfortable and breathable.

Motion Transfer

Even though they are more responsive than most mattress brands, they have a low motion transfer coefficient. Because of Bio-Pur’s motion-isolation when you sleep with a companion their movements shouldn’t cause disturbance to the mattress.

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

Edge Support

Edge support varies among the Amerisleep mattresses. The more firm models allowed us to feel more comfortable sitting or sleeping on their edges (the AS1 and AS2). We sense less edge support, especially while we are lying down, after upgrading to the more soft models.

Durability

All of Amerisleep’s mattresses are made from high-density materials and are constructed to last. As a result we believe that the mattress will last between seven and ten years in minimum.

Off-gassing

The Amerisleep mattresses do show some initial off-gassing, but this is expected given that they are shipped in a box. For a mattress purchased online, the scent of chemicals will dissipate in 48 hours.

Noise

As we move around on our Amerisleep mattresses, they don’t produce any obvious noise. In the end, you won’t be able to listen to your partner’s movement through the house at evening.

Sex

Mattresses from Amerisleep are more responsive, 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 a more difficult time moving your partner around.

Warranty Info

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

Amerisleep Hybrid Mattress Review


Alongside Amerisleep’s renowned all-foam mattresses is now offering hybrid alternatives. The Amerisleep AS3 Hybrid product is an mix of its all foam AS3 model and we’re here to share our experiences with it.

Support layers are the main distinction between these two models. AS3 Hybrid has zoned pocketed coils, while AS3 all-foam has a foundation polyfoam base. However, like the AS3’s all-foam counterpart AS3 Hybrid, AS3 Hybrid is also a polyfoam. AS3 Hybrid features Bio-Pur foam on top.

The AS3 Hybrid’s coils give it extra support over the AS3 mattress’s all-foam counterpart. Therefore, it’s a good choice for heavier individuals who require additional support. As a result, the AS3 Hybrid mattress has a greater airflow due to the coils, making it a cooler mattress overall. When it comes to cost it is it is the AS3 Hybrid mattress is going cost around $200 more than AS3 foam mattress.

The Amerisleep foam mattresses are the most suitable choice for those on a tight budget or in the lighter end in the range. In the event that you’re heavier or want an additional mattress that’s permeable then the Amerisleep hybrid models are the ideal choice.

 

Summary Amerisleep AS4


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

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

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