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 activities like driving or working at a desk. By promoting a natural curve in the lower back, lumbar supports can alleviate discomfort and prevent back pain. These supports come in various forms, including cushions, belts, and ergonomic chairs. Many are adjustable to fit different body types and preferences. Regular use of lumbar supports can contribute to better spinal alignment and overall comfort during prolonged sitting.
