Optimus Lumbar Support
Extra-Large Curved Lumbar Support-Fully envelops the lower back like two supporting hands, eliminating the "gap" or inadequate support common in ordinary lumbar cushions.
90mm Free Up-and-Down Adjustment-Allows precise alignment with your lumbar spine curve, whether you're tall or short, and regardless of sitting posture.
High-DensitySlow-Rebound Inner Core-Dynamically distributes pressure and maintains the natural curvature of your lower back even during long sitting sessions.
