Lumbar supports are devices designed to provide support to the lower back, helping to maintain proper posture and reduce strain on the spine. They are commonly used in chairs, car seats, and during long periods of sitting to alleviate discomfort and prevent back pain. These supports can come in various forms, including cushions, belts, and ergonomic chairs. By promoting a natural curve in the lower back, lumbar supports help distribute weight evenly and encourage a healthier sitting position, making them beneficial for office workers, drivers, and anyone who spends extended time seated.
