Please Check Before Ordering
- This is the 260mm total length version — check your existing cylinder length matches, or that 260mm gives you the seat height you need.
- Confirm your chair uses a standard 28mm taper connection (see technical drawing photo).
- Not sure? Send us a photo of your current cylinder — we'll check compatibility before you buy.
Installation
Remove your old cylinder from the seat and 5-star base, then press-fit the new cylinder into position. No special tools required.
