The Stimulite Bariatric 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 Bariatric cushion and the extra polyester cover at the same time (not separately).
The Bariatric model is made of the same perforated and breathable, open cell structure as Supracor's other Stimulite cushions. The cushion's excellent breathability (as compared to other types of cushions) assists in the prevention of skin maceration. The Stimulite Bariatric also comes with a polyester cushion cover.
Supracor's Stimulite Bariatric model is designed especially for people who benefit from a cushion with a greater weight-bearing capacity.
