A wheelchair for controlled environments includes a pair of tubular sideframes interconnected by a seat and a backrest. Sockets are welded to the sideframes for receiving pins on the underside of the seat. The position of the backrest is adjustable and the backrest is separated from the seat by a gap to avoid trapping contaminants. All metal components of the wheelchair have in integral outer surface. Tacky rollers clean the wheels as the wheelchair rolls and mechanically couple a power unit to the rear wheels. The power unit is controlled from a keyboard attached to a tubular armrest on the wheelchair. Control and signal cables from the keyboard are located within the armrest. A protective garment is provided with the wheelchair to contain contaminants in the clothing of the user and to protect the user.
