When it comes to wheelchair design, it seems a given that lighter is better. Today's ultralight chairs now weigh in at well under 20 pounds.
Bariatric wheelchairs are wheelchairs built for people who are obese.
The Brownstone chair was designed to carry a person up to 900 pounds. Pat O'Rourke, owner of Brownstone, reports that the chair has been tested to 950 pounds, but that most people who purchase it are in the 800 pound range. The side frames are built out of 6061 T-6 aircraft aluminum. The chair folds like a standard wheelchair, but it has two sets of cross bars instead of the usual single set. The cross bars are made out of chromolly steel.
