Overview of Benefits

The Amerisleep brand of designers and engineers carefully source and select materials for unique performance characteristics. The brand is continually improving the quality of its mattresses based on the latest technology and customer feedback. Customer satisfaction is a key to their success, an important factor in considering your mattress buying options. The top-selling Amerisleep AS3 is an all foam mattress constructed of 3 different layers, totaling 12 inches in height.

The AS3 is formulated to have a medium firmness and lies in the mid of the Amerisleep line. The amalgamation of the memory foam comfort layer and the poly foam below should provide a right mix of pressure relief and support. The sheets are a combination of Memory Foam, Poly Foam, and High-Density Poly Foam Base. Each layer offers a specific feature for body contouring, enhanced comfort, pressure relief sleep and deep compression support.

For example, below the comfort layer is a 2-inch layer of poly foam with a 1.65 lb density. This foam is a bit solid, it not only acts as a transition layer between the soft memory foam above and the firm base below but to provide some bounce to the mattress so the sleeper wont feel stuck when trying to adjust their position. Amerisleep AS3 mattress is preferred by sleepers who love a pressure relieving foam feel and change positions while sleeping. The different layers offer cool comfort and supportive rest. Do you sleep on your side, front or back?

The Amerisleep AS3 has a medium-firmness level. The high-density poly foam, this layer is firm to support the comfort, and transition layers above as well as provide in-depth compression support to the sleeper on top of the mattress. The base not only gives the AS3 its shape but also provides the mattress with some durability. Along with this, the breathable cover and convoluted transition layer combine to provide more airflow through the bed for improved temperature regulation.

Technology Details

The Amerisleep AS3 is a memory foam mattress comprising 4 lb. plant-based memory foam with a transitional Affinity layer for a plusher support level.

The top comfort foam layer is a 3-inch layer of open-cell Bio-Pur foam that is designed to be breathable and has the cooling technology to wick away heat and moisture. It is intended to be responsive to each sleeper and relieve pressure points while conforming to the curves of the body. It also offers some support when paired with the other layers to allow more massive body parts to be held up to promote natural spinal alignment.

The support core comprises a 2-inch foam layer and a 7-inch foundation support layer. However, the 2-inch layer is a transition layer that reasonably supports weight across the mattress and relieves pressure. The 7-inch Bio-Core layer is a dense support foam layer that offers a firm foundation for the mattress.

The top layer cover of the Amerisleep AS3 mattress is constructed of various materials including Celliant, a plant-blend material applied to make the fabric cover more breathable. The benefit of Celliant is unique to mattress covers and is blended with polyester and spandex. The AS3 models mattress cover can also be unzipped for easy spot cleaning.
