Tomorrow Sleep and Amerisleep are both online sellers of mattresses that incorporate foam and are available in multiple firmness levels.

This mattress comparison will outline the similarities and differences among these two companies’ options to help you decide which company will give you your best option.

Tomorrow Sleep Construction
- Tomorrow Sleep’s Medium Soft and Medium Firm versions have similar construction.
- The cover is polyester and nylon.
- A 1-inch layer of memory foam with phase change material sits on top.
- Second is a layer of gel foam, providing comfort and bounce. This layer is thicker in the Medium Soft option.
- The Medium Firm option has a layer of memory foam-like “dynamic response foam” under the gel foam layer.
- In both firmness levels, there is a 6-inch support layer that consists of individually pocketed coils. The Medium Firm option uses thicker coils.
- A foam side rail system reinforces edge support.
- 1 inch of stabilizing foam forms the base.
- 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.
- Amerisleep has more firmness options.
- Tomorrow Sleep incorporates springs and a side rail system for edge support.

- Tomorrow Sleep addresses sleep temperature better because it incorporates springs, though Amerisleep also uses special materials to ensure you stay cool.
