Long hours at a desk, in the car, or on flights can strain the lumbar region. If you constantly shift positions or feel pressure in your lower back, your seat lacks lumbar support. Your spine has a natural curve. Without ergonomic reinforcement, that curve collapses under prolonged sitting. Kusho Lumbar Back Pro Cushionengineered to stabilize posture and maintain natural spinal alignment — delivering consistent, uninterrupted support.
