Product Features

What’s the first thing that pops into our heads when buying a mattress? Is it comfortable? Is it expensive? Is it right for my specific needs?

Let’s check out some of these features and see:


Below we outline the materials the Amerisleep AS3 mattress is made of and break down its layers.


The AS3 mattress consists of:

  • Cover made from blended cotton and polyester
  • Bio-Pur memory foam containing plant-based oils
  • Bio-Core polyfoam also with plant-based oils
  • Polyfoam with Surface Modification Technology (SMT)

The fabric of the cover is soft and breathable, which helps with temperature regulation.

The Bio-Pur and Bio-Core foams have an open-cell structure that further improves ventilation. These materials’ use of plant-based oils makes the mattress more eco-friendly than those containing petrochemicals.

The Bio-Core polyfoam’s density and thickness vary for each Amerisleep mattress model.

The Polyfoam with SMT is an integral part of all Amerisleep mattresses (except the A1). Mattresses that rely on this technology have a surface that’s not altogether the same but rather divided into five sections, each dedicated to a different body part:

  • Head
  • Shoulders/back
  • Hips
  • Upper leg
  • Lower leg

These sections are designed to offer different cushioning and support for each body part, making the mattress healthier and more comfortable.


The AS3 has four layers. Let’s explore each of them:

Comfort Layer

Amerisleep mattresses usually have a thinner comfort layer than comparable hybrid products. In the AS3, this surface is made of memory foam that’s three inches thick and has a density of four pounds per cubic foot (PCF).

What does that mean?

If you press the AS3 with your hand, it won’t compress much, which is good. When you lay on it, it will just contour your body and provide pressure relief where needed.

Transition Layer

Under the comfort layer is the transition one—a two-inch-thick polyfoam sheet with a density of 1.65 PCF. The part gives the mattress its bounciness.
The AS3 isn’t too bouncy, though. When you move around on the surface, it adjusts to your movements.

Support Layer

Next, we have the support layer, 7 inches thick and has a density of 1.8 PCF. This one is firmer than the other layers and provides deep compression support.

Base Layer

Underneath all other layers is the base layer. It’s made of high-density, foundational foam and doesn’t compress easily, making the mattress more stable and durable.


Comfort is an individual, and everyone experiences it in different ways.
Below we explore the properties of the Amerisleep AS3 mattress and what they mean for comfort.


The firmness of the AS3 is medium. Testers gave it a score of 7/10, with 6.5/10 considered average on the firmness scale. It provides stable support and pressure relief, making it comfortable, no matter what position you sleep in.


How much you sink in this mattress depends mainly on what kind of a sleeper you are. Let’s review AS3’s specifications and what they mean for the different sleeping positions:

  • Side sleepers love the Amerisleep AS3. As noted earlier, the mattress has several zones that provide varying cushioning levels for the different body parts. The mattress is designed to compress more for parts that sink the most, i.e., the shoulders and hips, to help avoid back pain and other aches.
  • Back sleepers of average weight enjoy this mattress. If you weigh more than 230 pounds and sleep on your back, though, this mattress might be too soft for you.
  • Stomach sleepers may not be as comfortable on the Amerisleep AS3 because of its softness. That’s unless you weigh less than 130 pounds, in which case you probably won’t sink that much.


Because it’s made of memory foam, the AS3 mattress is very soft. That’s why it might feel a bit unstable, especially if you’re close to the edges. If you’re over 230 pounds, you may feel the reduced support even more.

Temperature Neutrality

Nobody wants to be too hot while they sleep.
Memory foam is famous for trapping the body’s heat, but this mattress is made from a material with an open-cell structure that helps keep you cool.
Both the cover and the transition layer allow air to flow freely and help to regulate the temperature.

Motion Transfer

One of the great things about the AS3 is that there is almost no motion transfer. This helps avoid disturbances from your partner’s movements and makes it harder to change positions on the mattress.

Durability and Maintenance

To prove that their mattresses are very durable, Amerisleep gives you a 20-year warranty.

Of course, with proper maintenance, you can make your mattress last even longer. Here are some tips to achieve that:

  • Provide proper support for your mattress
  • Wash the mattress cover regularly
  • Wash your linens regularly
  • Avoid jumping on the bed

Every manufacturer shares specific cleaning instructions, and so does Amerisleep. By following them, you increase your mattress’s life-span.

  • Via email—[email protected]

Terms of Sale

As mentioned earlier, the AS3 comes with a 20-year warranty.
In the first ten years, you have a full replacement warranty.
You have a prorated warranty in the next ten years, which means you can replace the mattress, but you will have to pay 50% of the original purchase price and the shipping fee.

Who Can Benefit from This Mattress?

Choosing the best mattress brand has implications not only for your comfort but for your health as well.

What health benefits can you expect when sleeping on the Amerisleep AS3?

The mattress isolates motion throughout the surface, so it’s great for light sleepers or those bothered by their partner’s movements throughout the night. It’s also not squeaky, which is a big plus.

The mattress’s stable support is perfect for side sleepers and snorers. The Amerisleep AS3 is best for people who weigh less than 230 pounds—light to average weight sleepers will get the most out of this mattress because of its medium firmness and body contouring properties.

The AS3 is also recommended for physically active people. Why? The Celliant fabric used for the covers helps the body recover after physical activity by aiding blood circulation and oxygenation.

Who Should Look Elsewhere?

A few of this mattress’s properties may not be ideal for some people.
The AS3 is fairly soft, which means you will sink into it, especially if you’re heavier. This increases heat retention and might make you hot despite its improved air circulation.
Because of the softness of the mattress, the edge support might feel a bit unstable. The AS3 also lacks bounce, which means it might be less than ideal for sex.
There can be a little off-gassing with this mattress, although it should disappear a few hours to a few days after unboxing.


Let’s compare the Amerisleep AS3 to a couple of alternatives.

Amerisleep vs Casper

Both of these mattresses are made of foam, and they provide a 100-night sleep trial. Their pricing is very similar, too. However, Amerisleep has a 20-year warranty, while Casper offers only 10.
But Casper is better for people who prefer bouncier mattresses and back sleepers who want more stable support.

Amerisleep vs Puffy Lux

Puffy Lux’s prices are a bit higher than Amerisleep’s. The Puffy Lux is also softer and thicker. The Amerisleep is best for side sleepers, while the Puffy Lux is more or less compatible with any type of sleeping position.

Amerisleep AS3 User Reviews

The Amerisleep website features thousands of reviews by real users. To be more precise, Amerisleep mattresses have an overall rating of 4.7/5 by more than 15,000 customers.
Let’s take a look at some of these reviews.




If you enjoy soft and breathable mattresses, then the Amerisleep AS3 may be right for you.

The Amerisleep AS3 is great for people who don’t weigh much and sleep on their backs because of this mattress’s balance and contouring. It provides good spinal support and relieves pressure from hips and shoulders, making it an excellent choice for side sleepers too.

We hope our Amerisleep AS3 Review helped you decide whether this product is the best fit for you.


  1. Where are the mattresses made?

Amerisleep mattresses are made in the US, making it possible for the company to ship within a few days.

2. What do I need to do to care for my new mattress?

While it’s not required, it is strongly recommended that you use a mattress protector. That way, your Amerisleep mattress will last for decades. (That’s why the company offers a 20-year warranty)
The mattress cover is removable, so you can wash it whenever you like. Use a cold and a gentle cycle, and hang it to air dry.
You shouldn’t flip or rotate your Amerisleep mattress because of its specific design.

3. Will my mattress make me hot when I sleep?

Overheating is a common problem with traditional memory foam. Less-breathable, petroleum-based foam mattresses trap heat. But the AS3 is designed to keep you cool and comfortable at night.
