💡 Why do pneumatic desk lifts fail during regular computer use?

You typically spot worn seals when the seat drops slowly under normal pressure.

- Damaged valve stems reduce upward thrust capability across daily shifts.
- Worn O rings let pressurized nitrogen escape past the main shaft.
- Installing a fresh steel piston brings handy lift recovery to worn frames.
- A reliable lift assembly prevents back strain through proper hip alignment.
