Amerisleep AS1 Mattress Review – Our Video Analysis

Is the Amerisleep AS1 a Good Mattress for You?

Before we dig into the performance of the AS1, let’s go over who I do and don’t recommend this mattress for.

Who I Recommend the Amerisleep AS1 Mattress for

I’d recommend the AS1 for anyone who loves a firm mattress. There is a soft memory foam layer on top that provides a bit of pressure relief but the overall feel of the AS1 is very firm. The high density poly foam base layer provides much of the feel for this mattress, leading to a very supportive and firm structure.
I’d also recommend the AS1 for hot sleepers. Amerisleep uses a cooling cover and a special memory foam that helps to draw heat away from the body to help people sleep a bit cooler.
Finally, this mattress is a great option for both stomach and back sleepers. The mattress is extremely firm which will help keep your hips from sinking too far into the mattress. By keeping your hips up, the AS1 will align your spine in a better position while you sleep, helping to avoid aches and pains in the lower back when you wake up.

Who I Don’t Recommend the Amerisleep AS1 Mattress for

I think this mattress is too firm for side sleepers, who need a mattress that allows them to sink in for pressure relief on the hips and shoulders. If you’re a strict side sleeper or a combination sleeper who is often on their side, I’d recommend a soft mattress instead.
Similarly, I wouldn’t recommend the AS1 to anyone who loves the feel of a soft mattress that envelops you into the bed. I definitely felt that I was lying on top of this mattress, rather than sinking into it deeply.

How Firm Is the Amerisleep AS1 Mattress?

Everyone will feel the firmness of a mattress a bit differently due to differences in body type and weight. Instead of just giving my opinion on the overall firmness level, I enlisted three other people to give their opinion as well. This will give you a better sense of the firmness range you can expect from the AS1.

Amerisleep AS1 Firmness Ratings

All of the Sleepopolis testers found the AS1 to be near the top end of the firmness scale.This goes along with Amerisleep’s intention of having it as the firmest mattress in their line. I rated the AS1 as a 8/10 on the firmness scale and found that much of the feeling for the mattress was provided by the firm polyfoam base. When I first pressed into the AS1, the feeling was of the soft memory foam comfort layer. While this is a soft layer that provided some contouring to my hand, it is only 2 inches thick which meant that I easily interacted with the layer below. After I pushed in a bit further there was a quick transition to the high density poly foam beneath, which gave the mattress a firmer feeling.

Amerisleep AS1 Mattress Performance

In order to give you a full picture of how the AS1 performs, I’ve used a few different methods to test it. In this section, I’ll go over how the mattress performs for different sleeping positions, pressure relief, and concerns for couples, like motion isolation, cooling, and edge support.

Testing the Amerisleep AS1 Mattress In Different Sleeping Positions

When choosing a mattress, it’s important to consider your primary sleep position and your body type, because these factors can determine how a mattress feels to you. The best mattress for a lightweight side sleeper can be very different from the best mattress for a heavyweight stomach sleeper. Everyone has different needs from their mattress, so let’s take a look at how different sleepers might feel on the AS1.

Is the Amerisleep AS1 a Good Mattress for Light Sleepers (Under 130 pounds)?

Light Back Sleepers – Thanks to the firm feel of the AS1, light back sleepers should get all the support they need, along with good pressure relief, to prevent any aches and pains.
Light Side Sleepers – This mattress is very firm and doesn’t offer too much cushioning on the shoulders and hips, so I think it’s not going to be very comfortable for light side sleepers.
Light Stomach Sleepers – Like back sleepers, light stomach sleepers will likely be very comfortable on the AS1, as it does a great job of keeping the hips elevated.

Is the Amerisleep AS1 a Good Mattress for Average Weight Sleepers (130 – 250 pounds)?

Average Weight Back Sleepers – Average weight back sleepers should be comfortable on the AS1. The mattress offers a nice mix of support and pressure relief while lying on your back.
Average Weight Side Sleepers – The AS1 is probably going to be too firm and not offer enough pressure relief for average weight side sleepers. I’d recommend something that allows for more contouring around pressure points.
Average Weight Stomach Sleepers – Stomach sleepers generally want a firm mattress and the AS1 should do the trick for average weight stomach sleepers. It’ll keep your hips elevated, which prevents lower back pain.

Is the Amerisleep AS1 a Good Mattress for Heavy Sleepers (over 250 pounds)?

Heavy Back Sleepers – The AS1 should be a comfortable pick for heavy back sleepers. The mattress does a good job of maintaining spinal alignment and supporting the hips.
Heavy Side Sleepers – Heavy side sleepers likely won’t get enough pressure relief from the AS1 because it is firm and doesn’t have much cushioning. I’d recommend a hybrid bed that offers strong support, but has a plush comfort layer to offer pressure relief.
Heavy Stomach Sleepers – The AS1 may work for some heavy stomach sleepers, as it is firm and does a good job keeping the hips elevated. But a hybrid mattress that uses supportive coils in its construction might be a better option to ensure heavy stomach sleepers get enough support.

Amerisleep AS1 Mattress Pain Relief Performance

If you’re waking up with aches and pains every day, your mattress could actually be the culprit behind this discomfort. Depending on your body type and sleeping position, you’ll need a different mix of pressure relief and support to prevent pain. For example, side sleepers want a mattress that contours around their pressure points— the hips and shoulders—and relieves pressure. To give a visual representation of where someone may feel pressure points while lying on the Amerisleep AS1, I placed a pressure map on top of the mattress and lied on my back, side, and stomach. In the image below, pressure will be represented from blue (low pressure) to red (high pressure).

Amerisleep AS1 Pressure Map

Back Pain – These results, particularly when I’m lying on my back and stomach, indicate that the AS1 should help prevent back pain. Even with the memory foam on top, I felt that the AS1 was firm and kept my hips from sinking in while I was on my back. This helped keep my spine aligned and in a good position to avoid aches and pains. Similarly, I found that the AS1 did an excellent job of keeping my hips up and my spine aligned while I was lying on my stomach. Side sleepers, however, are likely to experience back pain on this bed, as their hips and shoulders won’t sink enough to achieve a neutral spinal alignment. Shoulder Pain – Once I rolled onto my side I did feel some pressure begin to form at my shoulders. The pressure map results above show increased pressure on my side, which I was expecting on a mattress this firm. Side sleepers tend to prefer softer mattresses as they allow them to sink in for more pressure relief, so I would recommend taking a look at one of the softer options from the Amerisleep line. I also think back sleepers with shoulder pain might want something a bit softer. Stomach sleepers with shoulder pain should do fine here. Hip Pain – On my side, I experienced some pressure on my hips, which you can see in the pressure map results above. As with shoulders, I’d recommend a softer mattress here. For my back and stomach, the AS1 did a great job of supporting my hips and relieving pressure.

Amerisleep AS1 Mattress Performance for Couples

If you share your bed with a partner, there are a few things you might want to consider before buying a mattress. I’m going to take a look at motion transfer, cooling, how well this mattress should work for sex, and edge support, all of which are important factors in a mattress’s performance for couples.

Motion Transfer

If you are sharing the mattress with a partner, you will want to know what it will feel like when the other person gets into and out of bed or tosses and turns during the night. This next test is helpful in showing the intensity of disturbance that is detectable from one side of the mattress to the other. For this test I dropped a 10-pound steel ball from heights of 4 inches, 8 inches, and 12 inches and measured the disturbance on the other side of the mattress. This should be pretty intuitive: the bigger the lines, the bigger the disturbance.

Amerisleep AS1 Motion Transfer

The 4 inch drop, which simulates someone changing positions on the other side of the bed, shows very little motion transfer. The readings for the 8 inch drop, think someone climbing into bed, also show a great result for the AS1 on this test. While the 12 inch drop does show a higher spike in disturbance, as expected in this test, the tail of the disturbance is cut off pretty quickly.

Sex

When looking at how a mattress performs for sex, the ideal is a good mix of responsiveness and bounce. The AS1 isn’t the most responsive mattress—it’s not particularly bouncy and it responds to pressure pretty slowly, but still, I didn’t feel stuck trying to move around on it. I’d say it’s a decent mattress for sex.

Cooling

Just like two heads are better than one, two bodies produce more heat than one. So if you’re sharing your bed, having a mattress that keeps you cool can be a huge help in preventing overheating. The AS1 uses open-cell structure foam, which allows for more airflow within the mattress. More airflow means less hot air is trapped in the foam, ultimately leading to a cooler sleeping experience. A breathable cover, like the cover used in the AS1, will also help to prevent overheating.

Edge Support

If you plan on sharing your bed with a partner, and need to use the entire surface area of the mattress, then edge support is something you are going to want to take a look at. I have found that all foam mattresses can struggle to live up to the edge support of traditional innerspring mattresses, so I wanted to have a look at AS1 to see how I would feel near the side of the mattress. While lying near the edge of the AS1 I felt well supported on my back. When I moved close to the side of the bed there was some compression through the soft comfort layer, but it did not cause me to feel unstable on top of the mattress. Once I sat on the edge of the AS1 and concentrated all of my weight was concentrated over one area of the mattress. While I continued to see a little bit of compression through the top layer, I was pretty impressed with how the firm base layer held up to the increased weight. Overall I thought the AS1 performed well on the edge support portion of the review.

What Is the Amerisleep AS1 Mattress Made Of?

The AS1 is the firmest option available in the Amerisleep line. The mattress uses memory foam in the comfort layer but has a quick transition to a high density poly foam below, giving it a firm feeling for strong support. Additionally, Amerisleep’s mattresses are manufactured in the USA and all of the foams used in the AS1 mattress are CertiPUR-US certified for safety. Let’s take a closer look at each layer!

Amerisleep AS1 Cover

Cover – The cover for all mattresses from the Amerisleep line is the company’s Refresh Cooling Cover. It aims to draw heat away and keep sleepers cool at night. The company also says the fabric uses minerals to help promote daily performance and energy. Comfort Layer – The comfort layer of the AS1 consists of 2 inches of Bio-Pur foam. This layer will provide some contouring to the body and allow the sleeper to sink in a little for pressure relief. The memory foam does have a slow response to pressure, but with only 2 inches of it you won’t feel stuck in the mattress when changing positions. Traditional memory foam can have a reputation for trapping body heat, but the Bio-Pur foam has an open celled structure which will dissipate some heat to help sleep a bit cooler. Base – Immediately below the comfort layer is the Bio-Core foam base of the mattress, which consists of 8 inches of high density poly foam. This is a firm material that provides support to the mattress and the sleeper on top of the mattress. Because of the thin comfort layer and the quick transition to the base, this layer provides the firm feel to the AS1 mattress. This layer also acts as the foundation and provides the mattress with its shape.

Amerisleep AS1 Construction

Amerisleep AS1 Mattress Unboxing and Off-Gassing

The Amerisleep AS1 is a bed-in-a-box mattress, so it will be delivered to your house compressed and rolled into a box. Unboxing it is fairly simple: take the box into the room you want to set the mattress up in, open the box, remove the mattress and roll it out onto its base, and remove the packaging. Once the packaging is cut open, the mattress will start to inflate. You may notice a slightly unpleasant smell as the mattress inflates—this is known as off-gassing. Essentially, gasses that were trapped in the mattress during the compression process are being released. It’s harmless, but I’d recommend letting the mattress ventilate for 24 hours before sleeping on it.

My Final Thoughts About the Amerisleep AS1 Mattress

Before I wrap up this review, here’s my final thoughts about the AS1 mattress.

My Favorite Things About the Amerisleep AS1 Mattress

What I like most about the AS1 is its performance for back sleepers and stomach sleepers. Because it is a firmer mattress, the AS1 offers solid support for back and stomach sleepers, but still has good pressure relief in those sleeping positions as well. The AS1 is also a pretty affordable option, which is always a plus. I’d say it’s also a really solid option for couples who are back and stomach sleepers, thanks to good motion isolation, cooling abilities, and solid edge support.

My Amerisleep AS1 mattress complaints

What makes the AS1 a great mattress for stomach and back sleepers is exactly what makes it not a great mattress for side sleepers. It doesn’t have enough cushioning or offer enough pressure relief on the hips and shoulders for side sleepers to be comfortable and prevent pain. I’d definitely recommend taking a look at one of the softer Amerisleep mattresses or my other recommendations for best soft mattresses.

Amerisleep AS1 Mattress vs Saatva Mattress

The Saatva mattress is an innerspring mattress that is available in three different firmness levels: plush soft, luxury firm, and firm. Between these firmness choices, there is a Saatva model for almost everyone.
One of my favorite features of the Saatva mattress is its rock solid edge support. That extra support around the perimeter is great for couples and is indicative of the mattress’s durability.
The sturdy coils and durability of the Saatva mattress also make it a great bed for heavy sleepers, as it offers extra support.
Learn more about this bed in my full Saatva mattress review.

The Saatva’s coil-on-coil construction provides a classic innerspring feel. It’s a good option for combo sleepers, who will want to feel free to switch positions and avoid feeling “stuck” in the mattress. It comes in three firmness levels, so you should be able to find one that suits your needs.

Other Models from Amerisleep

Now, I’ll compare the AS1 to some other mattresses in Amerisleep’s line of memory foam mattresses.

Amerisleep AS1 Mattress vs Amerisleep AS3 Mattress

The AS3 is the medium-firm bed in the Amerisleep line. That’s a firmness level that works well for a lot of different people, which is probably why the AS3 is Amerisleep’s most popular mattress.
It’s also a great mattress for couples, since it is so versatile, but also because it has really low motion transfer and stays cool, thanks to open-cell structure foam.
The AS3 also features the HIVE transition layer, which is a convoluted foam layer that looks like a honeycomb. This layer adds some bounce to the bed and also promotes airflow.
To learn more, read my full Amerisleep AS3 mattress review.

The AS3 is the middle firmness option in the Amerisleep line. This 12-inch mattress combines supportive design with pressure relief.

Amerisleep AS1 Mattress vs Amerisleep AS2 Mattress

The AS2 is the second firmest mattress in the Amerisleep line, after the AS1. That firm feel makes it a great mattress for back and stomach sleepers. The AS2 has a memory foam feel, but is still firm and gives the feeling of lying “on top” of the mattress.
Like the AS3, the AS2 features the HIVE transition layer, which makes it a bit more responsive than the AS1.
The AS2 also performed well on the motion transfer and edge support tests, making it a good pick for couples.
Learn more in my full Amerisleep AS2 mattress review.

The second firmest of the Amerisleep line, the AS2 uses open cell memory foam in its comfort layer. The AS2 has a 3-inch transition layer of poly foam that provides bounce to allow sleepers to sink in without worrying about feeling stuck in the mattress.
