A back support is pivotally oriented to locate a pivot point relative to posterior superior iliac spines of a seated user, such that when an upper portion of the back support contacts the upper torso of the user and moves to a desired angular orientation to balance the upper torso over the pelvic area, the back support transfers support to the posterior superior iliac spines to maintain the pelvic skeletal structure in alignment. A lower portion of the back support angularly contacts, supports and confines gluteal and buttocks tissue of the user independently of the degree of pivotal orientation of the upper portion.
