SummaryThis lumbar stretcher uses an air-pump arch to ease back tension and support better posture. You lie on the curved base so your weight creates gentle traction while the adjustable air bladder sets the stretch height. OverviewThe stretcher features an ergonomic arch with ten pressure points that line up with key areas along your lower spine. You set it on a firm surface, lie back, and use the pump to raise or lower the arch. The design supports steady decompression, reduces stiffness, and helps restore natural lumbar curvature. Installation and Setup Place the stretcher on a flat, stable surface. Sit with the arch behind your lower back. Lie back slowly until the curve sits under your lumbar spine. Begin with the air bladder deflated for a mild stretch. Operation and Maintenance Pump air to increase stretch height. Release air to reduce pressure. Limit each session to ten minutes. Wipe the surface with a damp cloth after use. Store in a dry place and inspect the pump for smooth action.
