Amerisleep AS1 Mattress Benefits Overview

AmeriSleep is known for their innovation and dedicated customer satisfaction process. It has been serving for more than a decade to provide a premium quality mattress that promises to offer sound sleep.

AS1 is a memory foam mattress with a 10-inches high profile, featuring two layers of unique foams. Both layers work together to provide you the utmost comfort and pressure relieving support. The top layer is an Open-Cell structured memory foam supported by a high-density polyfoam. The mattress is topped with a breathable, stretchy cover made of polyester, spandex, and Celliant.

This specialized memory foam has a superb heat distribution system, contrary to conventional memory foam mattresses. It is most suitable for people who sweat a lot while sleeping.

The enhanced responsiveness of the very firm AS1 makes it a top choice among those who prefer sleeping on their back or stomach. Additionally, the heavyweight people find this firm surface quite comfy. It is made of eco-friendly materials that limit toxic off-gassing. If you are a side or combo sleeper, then the softer versions of AmeriSleep may be a better choice for you.

The construction of this mattress is highly durable and resistant to sagging. For couples, the motion isolation feature makes it excellent for bed sharing as you don’t get disturbed with your partner��s movements.

Amerisleep AS1 Mattress Technology Details

AS1 is 10-inches high with a combination of two superior quality foams. The mattress is designed to provide deep, restorative sleep for an energized tomorrow.

The Open-Cell Foam layer is 1-inch memory foam designed using Bio-Pur™ technology to provide ultimate comfort with a slight sink-in feel. The surface is highly responsive, offering instant bounce back when you change sides. The spaces between foam particles make it a breathable layer providing a cooling effect to those who sleep hot. It conforms to your body curves ensuring optimal support at core pressure points.

A High-Density Polyfoam is an 8 inches thick support/base layer of AS1. Integrated with Bio-Core™, this special foam is anti-sagging and does not lose shape even after years of use. It provides steady back support, even pressure distribution and leveled spinal alignment for instant pain relief. This thick layer is responsive to pressure making it most suitable for heavyweight profiles. The firm base strengthens the construction by adding durability and resilience to the mattress.

The polyfoam also has motion isolation feature that diminishes disturbances caused when sharing a bed. Its dense and firm structure makes it suitable for back and stomach sleepers.
