Quickie has developed a dramatic new approach to tilting in space. It's called the Quickie IRIS (Intelligent Rotation In Space). Unlike systems that incorporate a fixed pivot-point, dual pivot-point, or linear element, the Quickie IRIS' rotational design is based on the idea of rotating the seat-frame around a user's center-of-gravity. This, combined with up to 60° of posterior rotation and hi-resolution adjustment, provides the ultimate in control, maneuverability, and stability.
