ABSTRACT:
A chair is specifically designed to be usable as an ordinary office chair. The chair employs both anterior and posterior pelvic restraints to prevent rotation of the pelvic region. Several adjustment devices permit proper movement up and down and back and forward of the arm rests so that they may be used as anterior pelvic restraints during exercise.
