What Type of Mattress Is The Amerisleep AS2

The Amerisleep AS2 is an open-cell memory foam mattress specifically designed to combat back pain, more responsive than traditional memory foam.

How Well Does the Amerisleep AS2 Regulate Temperature? 

To stay cool during the night, the AS2 relies on open-cell foam that circulates airflow throughout the mattress and is more breathable the traditional memory foam mattresses. As one of the best cooling mattresses, Amerisleep also incorporates Bio-Pur material from plants to provide additional cooling.

Amerisleep AS2 Mattress Firmness & Feel 

When shopping for a new mattress, it’s important to understand mattress firmness levels. All mattress models are measured on a scale of 1 to 10, with 1 being the softest and 10 being the most firm. The Amerisleep AS2 has a medium-firm feel that is approximately 7 on the firmness scale, making it the best mattress option for back and stomach sleepers.

Is the Amerisleep AS2 Mattress Good For Couples? 

Memory foam mattresses provide quality motion isolation so couples do not disturb one another as they move around the mattress. In addition to motion absorbing foam, the Amerisleep AS2 also has a Bio-Core base layer that provides long lasting durability and prevents the mattress from sagging around the edges.

Amerisleep AS2 Mattress by Sleeping Positions

Back Stomach Side Combination
Medium-firm feel keeps your spine aligned and relieves pressure points. ✅High level of support provides proper hip support and spinal alignment.

❌The mattress might be a little too firm for some people’s stomachs.

The mattress might be too firm for side sleepers who need shoulder and hip cradling. For couples that share a bed, motion isolation prevents you from disturbing your sleep partner while changing positions.

❌The mattress can be uncomfortable when you’re on your side.

Back Sleepers:  As a 7 on the firmness scale, the Amerisleep AS2 will deliver the necessary support for back sleepers’ shoulders, back and hips while maintaining a soft contour for the body. Back sleepers need firmer mattresses to support their shoulders, back, hips and legs. 

See: Best Mattresses for Back Sleepers

Stomach Sleepers:  The best mattresses for stomach sleepers are firmer mattresses that give them enough support to prevent their hips from sinking in and throwing off spinal alignment. The AS2 is at the perfect level of firmness to comfortably accommodate stomach sleepers.

Side SleepersSide sleepers may find that the medium-firm feel of the Amerisleep AS2 is not soft enough to contour their shoulders and hips. While it features a soft comfort layer on top, it may not be thick enough to provide the cushioning needed to prevent soreness.

See: Best Mattresses for Side Sleepers

Combination Sleepers:

Since combination sleepers shift positions throughout the night, the AS2 suits those  who spend more time on their back and stomach rather than their side. Couples that share a bed will also like that the AS2 prevents motion transfer, which will keep them from disturbing each other’s sleep as they shift and turn.

Amerisleep AS2 Construction

Amerisleep AS2 consists of proprietary design technology such as HIVE, Bio-Pur, and Bio-Core, which work together to provide a uniquely comfortable, refreshing sleep experience.

The Amerisleep AS2’s Bio-Core base layer delivers unparalleled support that is designed to last for decades without sagging or developing soft spots. The layer above the Bio-Core is a HIVE transition layer that gives targeted support and pressure relief for optimum spinal alignment as well as head, back, shoulder, and hip support. 

Above the transition layer is the open-cell Bio-Pur design, which keeps you cool and refreshed while also contouring to your body and offering pressure relief. Finally, the top layer of the mattress is an ultra-breathable comfort cover that prevents you from overheating as you sleep.

Amerisleep AS2 Buying Experience

Shipping, Delivery & Returns

For residents in the contiguous United States, Amerisleep provides you with standard curbside delivery for free.. If you live in Alaska, Hawaii, Mexico, Canada, or any other region in the world, you can contact the company customer service line to get a quote on shipping and delivery.

Once you place your order for your new mattress, you can expect it to ship within 3 to 5 business days. From there, it can take approximately 1 to 5 business days to arrive at your door, and no signature is required for new mattress or accessory deliveries (excluding the adjustable bases). 

When your new mattress is delivered, please note that the drivers cannot help bring the mattress inside and will leave it outside your home. The freight agents will call you to schedule a 4-hour delivery window between 8am to 5pm. 

You can use your Amerisleep mattress with your existing box spring, but you will first need to place a 0.75-inch piece of plywood on top.

Amerisleep’s return policy is very customer-friendly and accommodating. Your new mattress purchase comes with a risk-free 100-night sleep trial. During that time period, you can return your mattress for a hassle-free refund. If you would like to try a different Amerisleep mattress, you can contact customer support and request an exchange. You’re entitled to one free exchange within the 100-night sleep trial period, and there are no hidden fees or penalties. The company will arrange for someone to come pick up the returned mattress, and Amerisleep works to recycle or donate used and returned mattresses.

Trial Period

With a 100-night sleep trial period, Amerisleep wants to ensure you are completely satisfied with your purchase.. That means for 100 nights from the date of delivery, you’re able to fully test out your mattress to see if it meets your standards. If for any reason you find that it’s not up to your liking, you can return it for a fast and full refund. In some cases, you might notice a difference in your sleep quality after the first night, but Amerisleep recommends that you give yourself at least 30 days to break in your new mattress to get the proper sleep experience.


Amerisleep stands behind the quality of all its mattresses, which is why the company offers a 20-year warranty, divided into two halves. Starting from the date of purchase, for 10 years, Amerisleep will replace or repair your mattress if there are any workmanship or structural defects. For the next 10 years, the warranty is prorated, and Amerisleep will replace your mattress for 50 percent of the original purchase price. The buyer is responsible for transportation and shipping costs for the new mattress.


Amerisleep mattresses are available for purchase on Amerisleep.com or at one of the many retail locations across the United States.

Care & Maintenance

Caring for your new mattress is necessary if you want to prolong its life and maximize your comfort level. Although not mandatory, Amerisleep highly recommends you use a mattress protector, which will safeguard against accidental spills.

The mattress covers are easily removable via the zipper, and can be washed in a cold and gentle cycle and then hung to air dry. 

Due to their specific construction and order of layers, the Amerisleep mattresses do not need to be flipped or rotated and are expected to retain their firmness levels for approximately 20 years.


Setting up your new mattress is simple. When the package arrives, take the box up to your desired bedroom. Some of the larger sizes can be heavy, so it’s advised that you have someone assist you with bringing the box up or down stairs. Remove your new mattress from the box and place it on your bed, ensuring the edges line up evenly. Using scissors, carefully open the mattress bag from the top end, and pull the plastic cover off from the foot.  

Once the mattress is out of the box, Amerisleep advises you to give it approximately 8 hours for the corners to expand. You can expect your new mattress to be ready for sleeping the first night you have it, but it may take a few days for your body to get used to it.
