A posture trainer properly supports the upper thoracic spine in relation to the lumbar region. The trainer's front surface transitions into a back surface at a periphery, forming a fluid-filled cavity. The back surface contacts a chair back; the periphery's base contacts the seat, and the front surface selectively contacts the seated person's back. A bottom portion has a first thickness between the front and back surfaces. A top portion has a bulging central region forming a second thickness between its peak and the back surface, being greater than the first thickness. The bulge position initially focuses pressure on, and supports, a portion of the thoracic spine in proper relation to the lumbar spinal region using the first and second thicknesses. Compression of the flexible thermoplastic causes bulge deformation to mold the trainer central portion to also provide spinal support between the lumbar and upper thoracic spinal regions. |
