What actually relieves lower back pain in a chair
An office chair cannot fix the underlying cause of lower back pain, but the right one can reduce the spinal load that makes sitting worse. The goal is simple: keep your lower back in its natural inward curve so your spine is not held in a slumped, flattened position for eight hours.
Three chair features do most of the work. Lumbar support that you can move up, down, and forward to meet your specific curve. A seat pan that fits your thigh length so the front edge does not press into the back of your knees. And a backrest with enough recline range that you can shift load off your lower spine throughout the day.
- Adjustable lumbar depth lets the support reach your curve instead of pressing your mid-back.
- Lumbar height adjustment matters because the belt-line target differs by torso length.
- Seat-pan depth should leave two to three fingers of clearance behind your knees.
- Recline with a lock or tension control lets you offload the lower spine periodically.
