The Quickie® SR45® tilt-in-space wheelchair features 45° of Intelligent Rotation in Space Technology and a simplified mix of options to provide proper positioning and comfort at an outstanding value. Intelligent Rotation in Space technology means the seat frame rotates around the user's center of gravity. This results in a smooth tilting motion that is easy for you to control and allows for the shortest possible wheelbase that is easy for you to maneuver. The SR45 features up to 45° of posterior rotation for improved positioning.
