Aussie Ergonomics wheelchair cushions are Australian made and registered class 1 medical devices (ARTG 410615). They are built of three layers of hard, medium hard and medium soft high density, high quality foam. Our cushions are designed based on extensive research, technical testing, and empirical patient feedback. Each cushion is unique and will be custom manufactured to specified width, depth, and height dimensions. The high-quality medical grade fabric has superb thermal qualities and is removable (zipper). Cushions are built on a flexible material to conform with the various wheelchair bases. An additional custom made lycra cover can be ordered as an easily removable and washable incontinence solution. Aussie Ergonomics wheelchair cushions are tested up to 250kg load.
