Sleepopolis maintains an affiliate relationship with some of the products reviewed, which means we get a percentage of a sale if you click over from our video (at no cost to our viewers). Also, many mattress and sleep product companies send us their products for free with the hope that we will like it and review it. However, there is certainly no guarantee that we will review it favorably. See our full disclosures here: https://sleepopolis.com/disclosures/

The Amerisleep AS4 (formerly known as the Colonial mattress) is the second softest mattress in the Amerisleep line. The Amerisleep AS4 mattress is a 13″ memory foam mattress constructed from 3 different layers of foam.

The top layer is 2.0″ of Bio-Pur+ memory foam. This highly responsive 4.0 pound memory foam is designed to provide great feel, softness, and pressure relief for the mattress. Bio-Pur+ is an all natural plant based memory foam designed and developed by Amerisleep. This results in a memory foam that sleeps incredibly cool and is able to breath much better during the night. The middle layer is 4″ SMT (Surface Modification Technology) foam. This pattern allows for better airflow by creating breathable channels, while also adding additional support and redistribution of pressure points in specific zones where it is needed most. The bottom layer acts as a foundational support layer. It provides a good base for the above layers, while remaining breathable.
