A wheelchair for large individuals includes front casters mounted substantially forward of the user's center of gravity. Front caster and rear wheels are mounted on the same rigid member. The rigid member is pivotally attached to the rear of the frame while the front includes suspension means extending between the rigid member and the frame. A side plate provides universal adjustability for positioning the backrest, for pivoting the armrests and for seat height and tilt adjustment. A telescoping tube engages the ground when the wheelchair is leaned back to prevent tipping.
