The Stimulite Slimline wheelchair cushion can generally be categorized as a honeycomb cushion due to its honeycomb-like structure. Supracor - the manufacturer of this product - specifies this cushion as follows.
The extra cover option refers to purchasing a Stimulite Slimline cushion (with or without the XS and sling options) and the extra polyester cover at the same time (not separately).
The Slimline's reduced profile (it is only 2+ inches thick) is designed for people whose condition presents a low susceptibility to decubitus ulcers. Its perforated, open cell structure permits more air circulation against adjacent buttocks and leg areas than most other types of cushions. The associated air circulation assists in the prevention of skin maceration. Note that the use of a non-porous cushion cover countervails the cushion's advantage with regard to air circulation.
The standard version of this cushion lacks the softness of some other cushion types. For this reason, Wheelchair Cushion Sage suggests opting for Supracor's "XS" option. The "XS" option specifies a softer top layer of the honeycomb material.
The low-profile form factor of this cushion, together with its excellent breathability, may also be helpful to non-disabled individuals who sir for prolonged periods of time (e.g., truck drivers, pilots, etc.). Of course, the Stimulite Slimline is also suitable for wheelchair-bound persons who have incurred a spinal cord injury (e.g., paraplegia, quadriplegia), stroke, or other disability.
