1. AS1

AS1 Review - Best Amerisleep Mattress for Back and Stomach Sleepers

Best Mattress for Back and Stomach Sleepers

In its all-memory foam mattress options mainly categorized on the firmness scale, The AS1 MODEL from Amerisleep is the firmest yet cost-effective.

Available both in-store and online on its home portal, the ASI memory foam mattress is the least expensive memory foam mattress option by this American brand Amerisleep.

The construction has an open-cell design that allows more airflow and provides you with more relaxed sleep.

Built with all Eco-Friendly materials and plant-based oils, its proprietary (exclusive) bio-pure foams offer a quick response in relieving pressure points, especially on the shoulders and hips.

Compared to other models by Amerisleep, the AS1 has the slimmest structure and has been designed with a 2-layer construction- the top is a 2-inch Bio-Pur foam comfort layer, and the base is 8-inch Bio-Core® foam.

These specially curated memory foams are more breathable and responsive to traditional memory foam.

In addition, the mattress is encased in a zippered cover made with a scientifically engineered cotton polyester fabric (contains Celliant), which helps regulate body temperature and improve blood circulation.

The AS1 bed in a box mattress is best for average-sized back and stomach sleepers. Again, it doesn’t wholly isolate motion, but it is sturdy and provides strong edge support because of its thick base layer.

The brand offers all standard sizes for all its models. Like all other Amerisleep memory foam mattresses, AS1 is compatible with a diverse range of bed frames and bases. However, unlike some other Amerisleep memory foam models, AS1 doesn’t have a hybrid version.

  • It doesn’t offer the cushion or support needed by heavier sleepers

2. AS2

AS2 Review - Best Amerisleep Mattress for Back Pain

Best Memory Foam Mattress for Back Pain

The 12-inch AS2 memory foam model mattress from Amerisleep is good in providing support and pressure relief as it’s a bit less firm but thicker than the AS1 mattress.

The model is also available in a hybrid version (foam plus coil construction design). Considered to be more apt for heavy-bodied sleepers, AS2 is more effective in spine alignment and offers back pain relief.

Like AS1, this model also uses the Bio-pure & Bio-Core memory comfort foam in its layering. The top layer is 2-inch bio-pure foam with a foundation, or the base layer is made with a 6-inch high-density bio-core polyfoam.

However, using an additional 3-inch dense HIVE transition layer of convoluted foam makes the Mattress more contouring and responsive.

In addition, the mattress is encased with extremely high energy transfer capabilities and a celiant blended fabric cover which has a pleasantly cool-to-the-touch feel.

It is more suitable for a stomach and back sleeper as it keeps the hips out of the mattress and the spine aligned in a straight line.

However, a strict side sleeper may not find it very comfortable. Sleeping on the side of the AS2 memory foam mattress will not put much compression on the top layer, proving to have good edge support.

The brand has free shipping and a hassle-free return policy overall the contiguous USA. But shipping to Hawaii, Alaska, and other international locations attracts additional charges. Again, white glove delivery is only available if both mattress and bedframe are purchased together.

3. AS3

AS3 Review - Most Popular Amerisleep Memory Foam Mattress

Most Popular Amerisleep Memory foam Mattress

4. AS4

AS4 Review - Best Amerisleep Memory Foam Mattress for Side Sleepers

Best Mattress for Side Sleepers

Amerisleep doesn’t believe that one mattress suits all. Different sleeping positions and sizes need a different kind of firmness in their beds. The reason the brand opted to design a more profound soft mattress AS4 for side and combination users.

With a profile height of 12 inches and medium-soft firmness feel, The AS4 mattress is ideally suited for an average and heavyweight side sleeper or those looking for standout motion isolation and precise contouring.

Constructed with the same built in3- layer design as AS3, this model has a deeper top layer of pressure-relieving Bio pure foam.

In addition, the AS4 has a 4-inch bio-based memory foam comfort layer, a one-inch airflow design transition layer, and a 7-inch foundation/support layer. The Amerisleep mattresses sleep you relaxed because of many reasons.

First is the outstanding ‘celiant blended’ mattress fabric cover, which has proved to be very breathable.

Secondly is the open cell structure of the plant-based memory foam, which helps in air circulation, and lastly, the convoluted hexagonal-shaped air channels that constantly provide airflow.

As a result, the AS4 offers a cloud-like comfort while keeping your sleeping surface 7-degree cooler than other mattresses.

It’s very comfortable and doesn’t give you a stuck or sinking-in feeling.

  • Type: Full

5. AS5

AS5 Review - Best Amerisleep Memory Foam Pluss Mattress

Best Plush Mattress

The AS5 memory foam mattress is the most luxurious & soft mattress in the line-up of Amerisleep. Available in either an all-foam or a foam hybrid version, the AS5 is for those who love to sleep on a plush bed with ultimate motion isolation.

With a profile height of 14′-inches, the AS5 is considered the thickest mattress from this brand. The AS5 is built with good and premium quality materials with multiple layering construction designs.

Just like other models from Amerisleep, the built starts with a top breathable cover made with excellent Celiant fibers that have a feature that prevents overheating.

Then comes the four-core layer constructions. Starting with a 3-inches Open Cell Bio-Pur memory Foam layer, which gives the bounce and responsive nature to the mattress—followed byan extra 2-INCH pressure-relieving responsive foam layer with Active Flex technology.

This layer is also responsible for imparting soft cushioning and more pressure relief to an average body side sleeper. Again, the Active flex-foam helps the user to adjust their positions a bit easier and without any interference.

The third layer is made with 2- inch foam that is convoluted to allow faster airflow, which is responsible for regulating temperature and helping you doze off much cooler. (in the hybrid version, the third layer has the pocketed coil setup).

This transition layer also has a support zone design that provides pressure relief in a targeted area of a body. The final layer is a base high-density polyfoam that is firm. This layer acts as a support layer and provides sturdiness and shape to the entire bedding.

The cloud-like feel of AS5 is outstanding. The mattress contours and conforms to your whole body, and as soon as you get out of the bed, the mattress pops back into place quickly.

Another benefit of sleeping on this mattress is experiencing superb motion isolation and motion transfer (especially in the hybrid version). Edge support in this memory foam mattress is fine, if not best.

Considered suitable for people who sleep hot, the AS5 mattress actually helps you sleep cool because of its aerated cover, open-cell bio-pure foam, and convoluted transition layer.

A perfect buy for those who don’t compromise on luxury for money!
