MATCHING NOTES
Separate height adjustment from backrest adjustment.
A chair gas lift connects the seat mechanism and base through dedicated interfaces. A separate lockable gas spring may control a backrest or leg section. Match the relevant component and release control, rather than choosing by chair appearance.

Seat height: chair gas lift columns
A chair gas lift sets the seat height of a swivel chair or stool. It is matched by its extended and compressed heights, its seat and base tapers and its release arrangement; sizes and options are on our office chair gas cylinders page. Two of the 12 published column references:
