Amerisleep Mattress Reviews
Customers shopping for a memory foam mattress are likely to come across the offerings from Amerisleep. This company, founded in 2010, has built its brand around the contouring comfort of memory foam.
In all five Amerisleep mattresses, customers will find Bio-Pur memory foam, which has a reduced environmental footprint compared to traditional memory foam. All of these beds also feature covers made from a breathable blend of cotton and polyester.
The Amerisleep models — numbered as AS1, AS2, AS3, AS4, and AS5 — have similar designs and materials, but there are important differences in firmness, layering, and performance. Price is another key difference, with the cost increasing progressively from the lowest-priced AS1 to the most-expensive AS5.
Understanding the central components of the Amerisleep mattresses can help customers determine which, if any, of these memory foam mattresses is the right choice to help them get quality sleep night after night.

Amerisleep Mattress Review Breakdown
The best way to start reviewing and evaluating the Amerisleep mattresses is by taking a close look at their construction.
Common Components in the Amerisleep Mattresses
Before getting into the design of each individual mattress, we’ll highlight some common components in all the Amerisleep beds:
- Cover: All Amerisleep mattresses are encased in covers made from blended cotton and polyester. The fabric is very soft and also breathable, which helps with surface-level temperature regulation.
- Bio-Pur memory foam: This is a type of viscoelastic foam (memory foam) that uses plant-based oils in place of some of the petrochemicals typically used in foam production. As a result, this material has a lower carbon footprint. Its open-cell structure is intended to enhance ventilation as well. The thickness and firmness of the Bio-Pur memory foam layer varies based on the Amerisleep mattress model; however, this foam has an above-average density of 4 pounds per cubic foot (PCF) and an ILD of 10. The higher density improves the durability of the mattress, and this ILD number offers a softer, more contouring feel.
- Polyfoam with Surface Modification Technology (SMT): This material is incorporated into all of the Amerisleep mattresses except the AS1. The SMT design, which Amerisleep calls their HIVE technology, means that the foam is not uniform in its feel. Instead, there are five zones — head, shoulders/back, hips, upper leg/knees, lower leg — that are built to offer more or less cushioning to different parts of the body.
- Bio-Core polyfoam: This base polyfoam is used in the support core of the Amerisleep mattresses. Like the Bio-Pur foam, it replaces some petrochemicals with plant-based oils. Density and thickness for this foam varies based on the model.
With this information in mind, it’s easier to understand the details of how each Amerisleep mattress offering is constructed.
Amerisleep AS1 Mattresses
The AS1 is the least-expensive and firmest of the Amerisleep mattresses. Its interior construction is simple and involves just two layers. The top layer is two inches of Bio-Pur memory foam, and the bottom layer is an eight-inch support core made of Bio-Core polyfoam. This Bio-Core foam has a density of 1.65 PCF and an extra-firm ILD of 40.
The memory foam layer gives the AS1 mild contouring even though the overall feel is Firm, falling around a 7-8 on the firmness scale.
- Stomach and back sleepers
- Anyone who wants a firm mattress with light contouring
- Shoppers looking for the lowest-cost option with Amerisleep’s well-regarded materials
- Firm feel: The firmness of the AS1 may be too hard for many sleepers, especially side sleepers.
- Thinner comfort layer: Customers who want a thick comfort system may find the two-inch memory foam layer on the AS1 to be insufficient for full pressure relief.
Amerisleep AS2 Mattresses
The AS2 is a three-layer mattress with a Medium Firm feel that is rated at around a 6 on the firmness scale.
Two different materials are used in the comfort system of the AS2. The topmost layer is two inches of Bio-Pur memory foam. The second layer is three inches of polyfoam zoned with SMT. This polyfoam has a density of 1.65 PCF and an ILD of 40.
The support core has a thickness of seven inches and is made up entirely of Bio-Core polyfoam with a density of 1.5 PCF and an ILD of 35.
- Side sleepers and most back sleepers
- People who prefer moderate contouring
- Shoppers who want a memory foam mattress but worry about sleeping hot
- Two-inch memory foam layer: Some people, particularly those who weigh over 230 pounds, may get better support and durability if the mattress has a thicker memory foam layer.
- One firmness choice: The AS2 is Medium Firm, which means people who want something that is definitively more firm or plush should look at other Amerisleep offerings.
Amerisleep AS3 Mattresses
The design of the AS3 is quite similar to the AS2 except that it has a three-inch layer of Bio-Pur memory foam and a two-inch layer of SMT-zoned polyfoam in its comfort system. The zoned polyfoam layer is slightly softer than in the AS2.
The combined effect of the thicker memory foam layer and the softer SMT layer is that the AS3 has a softer feel — rated as Medium (5) — and a higher degree of contouring than the AS1 or AS2.
- Plant-based Bio-Pur® memory foam is cooling, responsive, and pressure-relieving
- HIVE® technology provides zoned comfort and support, creating a weightless feel
- Balanced comfort and support ideal for side and combo sleepers
- Free, no contact fast shipping
- 100-night, risk-free sleep trial
- Easy and free returns
- 20-year warranty
- Made in the USA
Amerisleep AS4 Mattress
The Amerisleep AS4 has the same components as the AS2 and AS3, but the thickness of the interior layers changes substantially in this model.
In the AS4, the memory foam layer is four-inches thick, and the zoned/SMT polyfoam layer is only one inch. That SMT layer also has a much softer feel, which, when combined with the extra-thick memory foam layer, gives the AS4 a Medium Soft feel (a 4 on the firmness scale).
- Side sleepers, especially those under 230 pounds
- People who want pronounced contouring
- Sleepers who need standout motion isolation
- Heat retention: The amount of contouring from the four-inch memory foam layer may pose problems for hot sleepers.
- A big hug: While some customers prioritize deep contouring, for others, it can give the mattress a quicksand-like feeling.
Amerisleep AS5 Mattress
The AS5 is the thickest of the Amerisleep mattresses and includes a material that is not found in any of the other models.
That layer is called ActiveFlex foam, which is a type of polyfoam with a more latex-like performance. This means that it more quickly bounces back to its original shape, but it is still able to enhance overall mattress contouring.
A two-inch layer of ActiveFlex foam is used in the AS5 comfort system. It sits beneath a three-inch layer of the Bio-Pur memory foam and a two-inch layer of zoned polyfoam. The support core is seven inches of Bio-Core foam, giving the AS5 a total height of 14 inches.
The overall feel of the AS5 is Medium Soft — 4 on the firmness scale — with significant contouring but more bounce than other Amerisleep models.
- Sleepers under 130 pounds
- Side sleepers
- People who want the contouring of memory foam with an added touch of bounce
- Shoppers looking for a luxury memory foam mattress
- Higher price tag: Though the AS5 comes with added features such as the ActiveFlex foam layer, it also has a notably higher price point.
- Medium Soft feel: The AS5 is only available in a Medium Soft (4) firmness level, which is too plush for the preferences of many sleepers and the needs of most back and stomach sleepers.
Mattress Prices and Sizing
The most affordable Amerisleep mattress is the AS1, and prices increase incrementally with each model. A benefit of this product line of five mattresses is that customers have a wider price range to choose from.
Overall, Amerisleep mattresses are around the average or modestly above-average in price relative to other all-foam and memory foam beds on the market. However, the quality of their materials — including the cotton and polyester blend cover, high-density memory foam, and Bio-Pur and Bio-Core foams — helps both explain and justify the added cost.
Taking their build, performance, and price point into account, all of the Amerisleep beds can be considered a good value. While the AS4 and AS5 may be a stretch for some budgets, the AS1, AS2, and AS3 can be appealing options without putting as much strain on your wallet.
Each of the Amerisleep beds is offered in seven size options: each of the six standard sizes as well as a Split King. A Split King is composed of two separate Twin XL mattresses.
Sleeping Style and Body Weight
For many side sleepers, the Firm (7-8) feel of the AS1 is too hard to avoid impact at their pressure points. They may feel undue stress at the shoulders or hips and may find that there’s not enough cushioning to keep these areas in line with the rest of the body. These issues are most likely to arise for side sleepers under 130 pounds. Side sleepers over 230 may appreciate the firmer feel, but the fact that the comfort system is only two-inches thick may be problematic for people of a higher weight.
The AS1 is a good fit for back sleepers, especially those who weigh between 130 and 230 pounds. These sleepers can benefit from the firmness of the mattress while taking advantage of the Bio-Pur memory foam’s ability to lightly cushion the lower back. In some cases, people with higher body weights who sleep on their back may find that the thinner comfort system is not able to offer a full slate of pressure relief.
Just like with back sleepers, stomach sleepers usually do well with the AS1. It has enough firmness to meet their needs but adds a touch of conforming to keep the spine aligned. People who have a higher body weight, though, may do better with a mattress that has a thicker comfort system than the two inches offered by the AS1.
The AS2 rates well for side sleepers of any weight. Its Medium Firm feel has enough cushioning for hips and shoulders, and there is sufficient contouring to maintain healthy spinal alignment. That said, some people under 130 pounds may find it a little bit too firm, and some over 230 pounds may find it just a bit too soft, especially with a top layer that is just two-inches thick.
Back sleepers, especially those under 230 pounds, tend to find the AS2 to be a great match for their needs. It is able to combine a Medium Firm feel with a level of contouring that can smoothly cushion their midsection.
People under 130 pounds who sleep on their stomach often find the AS2 to suit their needs because they do not sink as much into the mattress material. While the AS2 can work for stomach sleepers over 130 pounds, they are at a greater risk of finding that there is too much hug around the midsection, and that risk is heightened for people over 230 pounds.
The AS3 is a hit with side sleepers because of its Medium feel and strong ability to compress in proportion to a person’s high-impact zones. The thicker memory foam layer has more cushioning for the hips and shoulders, keeping side sleepers from waking up with pain in those areas. A subset of side sleepers over 230 pounds, though, may find the AS3 to be slightly too soft for their liking.
Among back sleepers, the AS3 is the best fit for those who are under 130 pounds. For other back sleepers, the mattress may be workable, but many will find it to be too soft. But for those under 130 pounds who don’t sink as much into a Medium level of firmness, the mattress can comfortably cradle the lumbar spine.
For the most part, the AS3 is too soft and contouring for stomach sleepers. The main exception is stomach sleepers under 130 pounds who may find that the amount of give offered by the mattress is just enough given their lighter body weight and reduced pressure on the memory foam layer.
Thanks to its Medium Soft feel and excellent pressure relief, the AS4 serves the needs of most side sleepers. Its thicker memory foam layer can compress to lighten the load at hot spots while promoting a healthy spinal posture. Side sleepers over 230 pounds, though, may be more inclined to find that the AS4 is too plush.
For most people who sleep on their backs, the AS4 will be too soft. For back sleepers who weigh under 130 pounds, though, the softer, more conforming feel may not pose a problem and may actually be a welcome way to cushion the lower back.
Few stomach sleepers find the AS4 to be the right fit for them. It has too much hug and softness to keep them well-aligned, and they are also prone to feeling stuck in the mattress. The stomach sleepers most likely to be satisfied with the AS4 are those who are under 130 pounds and like a plusher feel.
The AS5 is a solid pick for side sleepers, particularly those who like a more plush and contouring feel. That includes side sleepers under 130 pounds who can get the most out of the deep conforming without the risk of pushing too far into the comfort layers.
With the exception of back sleepers under 130 pounds, most people who spend the night in this position find that their midsection presses too far into the AS5, reducing both their comfort and support.
Similar to back sleepers, most stomach sleepers are not well-suited to the AS5 and its Medium Soft feel; however, people under 130 pounds in this position may be a better fit for this softer, more conforming sleeping surface.

Amerisleep offers a selection of different memory foam mattresses. All Amerisleep mattresses are constructed to the highest standards, use high-quality custom memory foam, are manufactured in the USA, and can be a great choice for you depending on your sleep preferences.
- These mattresses could appeal to memory foam lovers. Every mattress in the Amerisleep line (AS1 through AS5) uses memory foam in its comfort layer. No matter the firmness level you choose, you’ll sink in a bit and enjoy the body-contouring characteristic of memory foam.
- Amerisleep mattresses tend to sleep pretty cool thanks to the open-celled memory foam and breathable Celliant cover. If you’re prone to overheating, this line could be a good option.
- As a general rule, Amerisleep mattresses do a nice job of isolating motion thanks to the memory foam, which has a slow response to pressure and absorbs a lot of movement. If you share the bed with a restless partner, an Amerisleep mattress could help you sleep undisturbed.
- The Amerisleep line doesn’t have the best edge support. If you need to utilize the whole surface of your mattress, you might want to consider a mattress with an innerspring build.
- The all-foam Amerisleep mattresses generally lack bounce. If you want to feel more on top of a mattress (instead of “in” it), then consider an innerspring or hybrid mattress.
