These are possibly the 2 most important characteristics of wheelchair cushions for wheelchair users. Presence of a cushion cover and type of support structure the cushion is placed on are the variables that will be investigated. Displacement of the cushion surface over a series of loads comparable to human masses was measured. Displacement of the cushion surface was measured using a 3-D digitizer (Minolta Vivid 900) and computer software Rapidform 2001. Simulation of cushion properties was then carried out using software CosmosWorks 2005. Results indicate that the foam cushion exhibits the best pressure distribution characteristic, while cushion covers tend to decrease deformation and increase pressure on bone protrusions. Simulations also indicated that a symmetrical cushion appeals not to be ideal for users with asymmetrical weight distribution. © ACM 2007.
