Abstract: A leg pillow having two opposing arcuate-shaped bolsters that defines a thigh channel. The bolsters are connected by a bridge having airflow channels on its upper surface and flex channels on its lower planar surface. The bolsters have terminal ends curving inward that form a friction fitting single leg clasp capable of clasping securely an inner thigh of an individual. The clasping of the thigh causes a deformation of the leg pillow which, when the alternate inner thigh rests on the lower planar surface of the bridge opposite the thigh channel, the flex channels therein allow for substantial conformity to the unique contours of the individual's lower body region, thus alleviating stress on the spine and maintaining the spine's natural alignment. The unique features of the present invention resist movement into the unhealthy prone or supine sleeping position and prevent shifting of the pillow while asleep.
