Back Sleeper. For people who sleep in this style, support for the lower back is crucial. Therefore, it's best to avoid very stiff spring mattresses since they have a tendency to push against the spine and not provide the correct curvy support.

Used for many purposes, memory foam is made from a substance called viscoelastic. Though it was invented back in the 70s (and was used by NASA), it wasn’t until much later that it was incorporated into sleep technology. It has been used traditionally on seats, different kinds of helmets, pillows, and mattress toppers. The foam reacts to pressure and heat, becoming softer with more heat or pressure. Since our bodies are warm, memory foam adheres to the body’s shape and returns to the original shape slowly after heat and pressure are removed. This makes it the perfect substance for a natural shape when sleeping. Instead of the body conforming to a stiff mattress, the memory foam compresses under curves to allow for a natural curvature.
