Lumbar Support
Lumbar support is an adjustable cushion in the seat backrest that supports the lower back.
What is Lumbar Support?
It can be manual or electric. Some systems adjust height as well as depth. It can make long drives more comfortable. Electric versions often have four-way adjustment and are stored in the seat memory on some cars. Seating experts recommend adjusting seat height, backrest angle and lumbar support together for the best posture.
How it works
An inflatable bladder or mechanical plate pushes forward in the lower backrest.
Why it matters for your car
Leaking air bladders or pumps can stop the function. Adjust it so the spine keeps its natural curve.
