I would say that important features of a lumbar support cushion would vary by person. It would be best if the cushion was rather long to fit your back width and height. It would also be best if it were some sort of flexible material so that it contours your back well.
When you compress a seat cushion, you are storing potential energy in the form of elastic potential energy in the cushion material. When the cushion is compressed, the material is deformed and stores this energy, which can be released when the cushion returns to its original shape.
When you sit on a cushion, your weight exerts a downward force due to gravity, compressing the cushion material beneath you. This compression causes the cushion to deform, distributing your weight over a larger surface area. The cushion's material then responds by providing resistance, which helps to support your body and maintain comfort. Ultimately, the interaction between your weight and the cushion's properties determines how well it absorbs and redistributes the force.
Cotton is a good material for a cushion because it is soft, breathable, and hypoallergenic. It provides comfort while allowing air to circulate, keeping the cushion cool and preventing the buildup of moisture.
