Abstract
A mobile seat arrangement is provided which is configured to collapse for ease of storage and transportation. An x-brace, a rear lock brace and a front racking brace help to hold the mobile seat arrangement in an upright position for use as a stroller, wheelchair, or other seating arrangement. The braces also facilitate the collapse of the mobile seat arrangement in a compact fashion. Placement hooks are also provided to place a seat and back portion into the frame of the mobile seat arrangement. The mobile seat arrangement can also be tilted, with the angle between the seat and back of the seat and back portion remaining constant as the frame is tilted for the user. Arm rests and foot rests are also included.
