OnlyTree Black
This Product was reviewed by Staying Alive Crew Last updated: Feb 17, 2022 at 10:59 am

This 12-inch all-foam Amerisleep AS3 mattress comes complete with a Celliant blend cover, a 3-inch top layer memory foam for a supportive mattress. 

Boasting a transitional 2-inch layer of polyfoam with 5 zones, complete with a high-density polyfoam support core. It provides the perfect balance of medium-firm. 

Whilst the Amerisleep AS3 is priced slightly higher than the average memory foam mattress on the market, the higher price is a result of the superior quality foams and eco-friendly materials used. 

Being a good samaritan may cost you a bit, but it’s worth it to get a green mattress.
