Amerisleep Construction

  • Amerisleep mattresses range in thickness from 10 inches for the firmest option, the AS1, to 14 inches thick for the softest option, AS5. AS2, AS3 and AS4 are the most similar in construction and contain three layers of the same materials, but in different thicknesses.
  • Amerisleep’s cover uses Celliant fabric, a material said to distribute thermal energy in such a way as to help with muscle recovery. The material is used in some athletic clothing.  
  • All of Amerisleep’s mattresses have a top comfort layer of Amerisleep’s Bio-Pur memory foam, designed to ensure cool sleeping. The thickness of this layer differs by firmness level.
  • AS1 and AS5 differ in their middle layer construction. AS5 has under its Bio-Pur layer an additional layer of a special foam that makes it softer and that is not included in other models. AS1 goes straight from the Bio-Pur comfort layer to a dense base layer.
  • The middle layer of the medium firm options (AS2, AS3 and AS4) is a supportive transition foam layer. This layer is thickest in AS2 and thinnest in AS4. AS5 also has a layer of this material.
  • All models except AS1 have a 7-inch base layer of dense support foam. AS1’s base layer is 8 inches thick.
