Will This Chair Gas Lift Fit My Chair?

Measure the total length of your old cylinder from the top of the pin to the bottom of the body. This one is 260mm.
Check the taper where the cylinder enters the 5-star base — most chairs use the standard 28mm taper.
Check seat height — a similar length to your old cylinder keeps the same height range.

Not sure? Send us a photo of your current cylinder and we'll confirm the fit before you buy.

Signs You Need an Office Chair Cylinder Replacement

Easy DIY Installation

Remove the old cylinder from the seat and 5-star base, then press-fit the new one into position. No special tools needed. Gas lifts are pressurised — never cut, puncture or heat the old cylinder.
