Replacement gas lift cylinder

The BFKK gas lift cylinder replaces a worn office-chair piston. It fits most chairs including salon, executive and work models plus rolling stools. The unit supports up to 1000Lbs and carries SGS and BIFMA certification. Silent 360° rotation keeps movement smooth and quiet.

Check compressed and extended height

Measure the old cylinder when fully compressed and fully extended before ordering. This unit compresses to 11.4 inches and extends to 13.9 inches, giving 2.5 inches of travel, which is higher than many standard pistons. Confirm those dimensions match your chair so the seat range stays correct.

Suits heavy-duty chair repair

Ideal for anyone fixing a sinking chair that needs a higher weight rating and certified safety. Not for buyers who need a different stroke length or a lower compressed height than 11.4 inches. Also not for stools or chairs with non-standard mounting sizes.
