What does camber mean?
Camber is the angle of the wheelchair's rear wheels in relation to the ground. Traditionally, the rear wheels are at 90° to the ground, so the camber measurement is 0. A negative camber (usually seen in sports wheelchairs) adjusts the angle of the rear wheels inwards, so they're easier to grasp - helping to manouvre your wheelchair with less force. The increased width from the spacing of the wheels also helps to improve lateral stability (but can also make it more difficult when navigating narrow environments).
