This two-piece adapter sleeve (split bushing) slips securely around a standard office chair’s gas lift cylinder, creating a larger clamping surface for your accessories and attachments. Its split design allows for quick, tool-free installation, and the snug fit ensures a secure grip without damaging the cylinder. Whether you’re adding a floating desk surface, footrest, cup holder, or any other clamp-on add-on, this adapter bridges the gap between the smaller diameter of the gas lift and the size your accessory requires.
If you want your gear to swivel with you rather than stay fixed at the base, mounting to the gas lift cylinder is the way to go.
This adapter was created to mount a “VIVO Office Chair Mounted 26 x 12 Inch Keyboard and Mouse Tray (MOUNT-KB08C)” onto a Steelcase Gesture chair. It also works perfectly with most accessories that typically attach to the larger wheel-base collar.

Most office chairs use a standard gas lift cylinder, so if yours does too, this adapter should be a perfect fit. It provides a stable platform for any accessory that needs a wider clamping surface, letting you position your setup exactly where you want it.
