Lumbar cushions, also known as lumbar supports, are ergonomic adaptations that improve posture by providing support to the lower back. These inflatable cushions are integrated into existing chairs or seats and come in various sizes. They are delivered including a hand pump with valve, allowing the user to adjust the level of support easily.

Lumbar supports help prevent back pain and offer comfort during prolonged sitting. They are ideal for medical devices such as wheelchairs and mobility scooters, as well as office chairs, cars, and other applications where ergonomics are crucial.
