Amerisleep AS4 Mattress Benefits Overview

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.

The medium-soft AmeriSleep AS4 is a memory foam mattress constructed of three different layers, totaling 12 inches in height. The amalgamation of the memory foam, comfort layer and the poly foam provides a right mix of pressure relief and support. Each surface offers a specific feature for body contouring, enhanced comfort, pressure relieving sleep and deep compression support.

The top is covered with a sheet made of polyester, Spandex, and Celliant that comfortably stretches across the mattress. Along with this, the breathable cover and convoluted transition layer combine to provide more airflow through the bed for improved temperature regulation.

This uniquely designed mattress has a ventilated structure allowing smooth airflow for a cool, comfortable sleep. It has a very active response to pressure as the mattress promptly bounces back to its uncompressed form as you turn sides. Surface Modification Technology (SMT) diminishes stifling or being stuck a common problem in conventional memory foams.

The soft contouring yet sturdy back support makes AS4 an ideal choice for side sleepers. Due to its exceptional motion isolation, the bed is best for couples and bed sharing with kids and pets.

Amerisleep AS4 Mattress Technology Details

AmeriSleep AS4 is a medium-soft, 12-inch high three-layered foam mattress designed to offer plush comfort, even weight distribution, and excellent lumbar support.

The top layer is memory foam with 4-inches thickness. It incorporates a unique Bio-Pur ™ technology for improved comfortability. The plush foam offers a slight dip but is still responsive to pressure. For a ventilated, cool sleep, the foam is designed using an Open-cell structure that distributes heat and enhances airflow.

Next is the Affinity layer,b1-inch thick in height. It is a layer of polyfoam surface has a perplexing (eggshell) design. This pattern develops space to allow air to flow through the mattress for enhanced temperature regulation and cooling of the bed.

Lastly is the base layer made of 7 inches thick high-density Bio-Core ™ poly foam. This layer is firm in feel, serving as the foundation of the product. Furthermore, it provides deep compression support to the sleeper. The base also maintains the shape over the years.

The top cover is designed using Celliant with 13 thermoreactive minerals to make the fabric highly breathable. It is blended with polyester and Spandex to improve the stretchability and strength of the material.
