Abstract: A pelvic embracing support device (1) which permits a user to sit comfortably for prolonged periods of time with less fatigue and discomfort including a pair of spaced apart flexible cushioned members (4) dimensioned to engage the trochanteric region (2) of the user's pelvis and a double-ended length adjustable strap (6) affixed to the support members (4) and including left and right loops (10) and (11) which are looped around the respective knees of the user so as to selectively pressure the support (1) medially against the illi (5) of the user's pelvis to compress and support the sacro-iliac joints (3) of the pelvis and anteriorly into the pelvis to tilt the user's pelvis into extension and reflexly produce lordosis of the lumbar spine so as to reduce shear forces on the pelvis and compressive forces on the spinal soft tissues while permitting free motion of the lumbar spine.
