I’ll be right in the middle of typing an email and my desk chair suddenly sinks down to the lowest setting completely on its own. How do I fix this annoying dropping seat without paying for an entirely new hydraulic cylinder mechanism?
This happens because the pressure seals inside your gas lift cylinder are worn out, causing the lifting gas to slowly leak out when you sit down.
A fast, budget-friendly DIY hack is to snap a piece of PVC pipe or a specialized plastic spacer kit around the exposed metal cylinder shaft to lock it at your favorite height forever.
Just keep in mind that if you use this trick, you won't be able to adjust the height dynamically anymore; if you still need to change levels for different tasks, you'll eventually have to buy a replacement cylinder online and swap it out.
