Task and operator chairs with lumbar pump are designed to provide enhanced lumbar support for users. The lumbar pump is a small air-filled cushion located at the base of the backrest, which can be inflated or deflated to adjust the level of support to the user's liking.
The lumbar pump is typically controlled via a small knob or lever on the side of the chair, allowing users to adjust the amount of air in the cushion to their desired level of firmness. This feature is particularly useful for individuals with lower back pain or other back-related issues, as it can help to alleviate discomfort and improve posture.
When shopping for a task or operator chair with a lumbar pump, it's important to look for a model that offers good overall adjustability, including seat height and backrest angle. This can help to ensure that the chair fits your body properly and provides optimal support throughout the day.
