Bariatric wheelchairs are designed specifically for users weighing over 18 stone (114 kg). Based on the standard wheelchair models, bariatric wheelchairs are available in a range of styles, self propelled, transit and transfer wheelchair styles, but are larger and much stronger. They are also designed with wider seats for greater support. As with all wheelchairs comfort is important and selecting seat width is the key to getting this right.
Other important differences include a wheelbase which is wider than a regular wheelchair for better maneuverability. The tyres offer the same level of cushioning for more durability and less maintenance, but are not pneumatic.
