Why Your Seat Needs This Lumbar Support
Long‑distance driving places exceptional strain on the lower back. Without proper support, the lumbar spine bears excessive load at the junction between movable and fixed segments, leading to muscle tension, pain, and potential long‑term health issues. This adjustable system provides:
- Maintenance of proper spinal alignment
- Reduction of muscle fatigue during extended drives
- Adaptation to various sitting postures
- Enhanced overall driving comfort and safety
Installation & Placement Guide
Placement: When fully retracted, the unit should be fitted with the seat back foam or attached to the other side of the seat back. Ensure the seat trim outline aligns with the user's torso, maintaining a distance of 90–100 mm for optimal positioning.
Installation Steps:
- Partially remove the backrest cover
- Unscrew the four mounting screws and release the foam from the frame
- When replacing the foam, avoid overtightening screws – maintain approx. 1 mm clearance
- Disconnect air hose connections
- Remove the air chamber from behind the rear cross‑braces
- Install the new chamber, ensuring correct orientation
- Replace the load plate if necessary
- Reassemble in reverse order
Note: Professional installation recommended for optimal performance.

Frequently Asked Questions (FAQ)
Q1: Is this lumbar support compatible with my existing seat?
A: Yes, it is designed to fit most air suspension seats from major brands (ISRI, Grammer, etc.). Check your seat's backrest internal space – the compact dimensions (55×60×8.5 mm) fit most standard cavities.
Q2: Can I install it myself?
A: Basic mechanical skill is sufficient, but we recommend professional installation to ensure correct orientation and air line connections.

A: 12 months. If any defect occurs, we will ship replacement parts promptly.
Q4: Do you offer dual‑chamber or triple‑chamber versions?
A: Yes, both dual and triple pneumatic lumbar support systems are available. Contact our sales team for details.
Q5: How does pneumatic adjustment work?
A: A small control valve (included or sold separately) inflates or deflates the air bladder, increasing or decreasing firmness. No electrical power is required – only compressed air from the seat's existing system or a small pump.
