An improved folding mobile seating structure with a seat and back portion movable relative to a framework, providing more comfort for the user. The seat and back portion may be moved relative to the supporting framework structure as a unit in a pivotal motion relative to the framework, or the arrangement may allow some degree of articulation between the seat and the back. The seat and back portion may be pivotal between an upright seating condition and at least a partial recumbent condition, and optionally to a flat horizontal condition. Telescoping tubes may be utilized for connection of the seat and/or the back to the framework for allowing the pivotal motion. Hand release actuators adjacent the handles may allow the seat and back pivotal motion to initiate when pressed and lock the seat and back portion in a fixed pivotal position when released. Incremental foot rests may be provided for the comfort of the user, and an overcenter hinge arrangement prevents the folding mobile seating structure from partially folding front-to-back when the front wheels encounter a stationary object.
