Abstract
A mobile body unweighted sit and stand chair assembly prevents repetitive stress from sitting, standing, and lifting objects for long periods. The assembly provides a vertically, rotatably, and pivotally adjustable seat, a restrictive support padding that rotates from a support bracket to selectively support the spine or the pelvis, and a frame for structural integrity, mobility, and steering. The seat supports the buttocks and the ischium region of the pelvis, tilting forward up to 35 degrees to abut the pelvis against the support padding. This forward position maintains the spine in a straight posture and forces open posterior intervertebral disc space. The seat is supported by an adjustable rod that supports the weight of user while sitting, walking, kneeling, or lifting. A frame includes wheels that enable mobility and a brake. A first bracket enables feet to steer for hands-free maneuverability. A second bracket provides balance during kneeling and lifting.
