Fix Sinking Office Chair Saver Kit - Stop Chair from Sinking

In this review of the Fix Sinking Office Chair-Chair Saver Kit, the bottom line is simple: if you have a chair that keeps losing height and you want to extend its usable life without replacing the gas cylinder, this kit is an affordable, practical fix. The reviewer found the set most valuable for users who need a stable seated height and for shops that perform quick chair repairs. It does not restore full up-and-down adjustment, but it reliably locks the seat at the chosen height and prevents the chair from sinking.

Key Features

• Stainless steel shafts: durable shafts resist bending and provide a long-lasting clamp around a 28mm or 1.1 in cylinder.
• Universal fit: the set is designed for most office chair gas lift cylinders with a diameter of 1.1 in (28mm), making it widely compatible.
• Simple installation: the top ring sleeve and lower ring install with included screws so the top ring slides and the lower ring locks tight to prevent movement.
• Complete kit: comes with two cylinder clamp shafts, two long bolts, and an L wrench so no extra tools are required for the basic installation.
• Quick solution: stops sinking in minutes by fixing the seat at the desired height rather than replacing the entire cylinder, saving cost for many users.

Who It's For

This kit is best for home office users, small businesses, and facility staff who want a straightforward, low-cost way to stop an office chair from repeatedly sinking and to extend the chair's service life. It suits chairs whose gas lift has failed but where rotation and other chair features still work fine.

It is not for people who need to restore adjustable height on a chair; the product does not repair the up-and-down adjustment function. Also, if the chair has a nonstandard cylinder diameter other than 28mm/1.1 in, a different solution should be sought.

Pros & Cons

Pros

• Durable stainless steel construction provides a robust clamp for the cylinder.
• Universal 28mm/1.1 in sizing covers the majority of office chairs with gas lifts.
• Includes necessary hardware and an L wrench for quick, tool-light installation.
• Cost-effective way to extend chair life and avoid buying a new chair.

Cons

• Does not restore height adjustability; it only fixes the seat at one chosen height.
• Requires basic manual installation and correct tightening of rings to work reliably.
