Office Chair Sinking Clamp, Pack of 2

This office chair saver kit stops your chair from sinking, keeping it at your chosen height without needing cylinder replacement or tools.

The kit includes two aluminium alloy clamps with securing screws that lock around your gas lift cylinder (25–28mm outer diameter). Installation is straightforward—no disassembly required. Simply position the clamp around the cylinder below your chair seat, tighten the screws, and your chair height is fixed.

Aluminium alloy construction delivers durability and long-term reliability, resisting the wear that damages plastic alternatives. The two clamps cover both your current chair and a spare, or allow you to restore multiple chairs in your workspace.

This design works with most standard office chairs across home offices, studies, and commercial environments. The included hexagonal wrench makes adjustment simple, and you can reposition the clamps if you later need to change your chair height.

Avoid the cost and hassle of buying a new gas cylinder. This kit extends your chair’s usable life by preventing sinking, maintaining comfort and stability through years of daily use.

Check your cylinder diameter (measure around the metal tube under your seat) to confirm compatibility before ordering. Once fitted, your chair will stay at the height you set.
