Seating and Mobility for The Severely Disabled
Published in Raymond V. Smith, John H. Leslie, Rehabilitation Engineering, 2018
A wheelchair cushion industry has developed in an attempt to resolve these pressure- related problems. A variety of technological approaches have been undertaken to remove or reduce the pressures in the more susceptible areas of the supporting pelvic surface tissues and underlying bony structures. These commercial developments have largely taken the form of cushions that are placed on the sling seat surfaces of conventional wheelchairs. They are also used with the newer ultralight designs. The primary purpose of these cushions has been the reduction of seat interface pressures. For many within this need group, these cushions have worked well. However, very little concern had been given by the cushion industry toward the needs for upper body support or posturing.

Interface pressure reduction effects of wheelchair cushions in individuals with spinal cord injury: a rapid review
Published in Disability and Rehabilitation, 2022
Wheelchair cushion is usually used for the management of sitting acquired pressure for individuals with SCI. It serves as an adjunct to the soft tissue of buttock to reduce high focal pressure underneath bony prominences and distribute pressure evenly over the whole contact area. Wheelchair cushions can be categorized as foam cushion, gel cushion and air cushion according to the filling material [10]. Wheelchair cushions filled with the same type of material can vary largely in design, e.g. foam cushion with flat design (e.g. Soft Pedal Cushion, Span-America Medical) or contour design (e.g. Jay® Basic, Sunrise Medical) or segmented design (e.g. Cubicushion®, Cape Trading Limited), air cushion with segmented air cell (e.g. Roho® Quadro Low Profile, Permobil limited) or individual air membrane (e.g. Vicair® Adjuster Cushion, Vicair limited). Interface pressure between body and wheelchair cushion, measured by pressure mapping system and presented as color-coded map/grid/numeric values [11,12], is a commonly used parameter to present the effect of pressure reduction.
The effect of cushion properties on skin temperature and humidity at the body-support interface

Clearly, no single cushion is ideal from all standpoints. The successful selection of an appropriate wheelchair cushion for a particular individual cannot be based on just one factor or clinical judgment. During the selection process, not only pressure distribution, but also the microclimate (heat and moisture control) between the body–seat interface should be considered. In this study, foam–fluid hybrid cushions produced the slowest rise in user skin temperatures, but the cushion material used did not significantly alter moisture accumulation.
Developing a process for assessing equivalency of wheelchair cushion pressure redistribution performance

Stephen Sprigle, Steven Pubillones
The ability to compare and contrast wheelchair cushion performance is important from both clinical and policy perspectives. During seating evaluations, clinicians attempt to identify a cushion that best meets the myriad needs of their clients. Because pressure redistribution can be a primary focus for some clients, a clinician would benefit from knowing which cushions offer relatively equivalent performance. This would allow clinicians to then assess other cushion features and characteristics to match the cushion to the needs of the user.
