Introduction: Fix the Sinking Chair - Failed Gas Lift Cylinder

About: Maker, Designer, and Blogger on the subjects of 3D design and 3D printing.

Do you have an office chair that keeps sinking under you? Chances are, you’ve got a failing gas lift cylinder on your hands. If you are the owner of a 3D printer, you can permanently fix your chair to the desired height with a simple 3D print job. In the past 10 years, we’ve bought 4 office chairs and 2 of them started sinking within a year. Turns out, this is a common problem with any chair that has a gas lift cylinder. Even chairs from well-known brands like IKEA may fail, which is why you see gas lift cylinder replacements for sale everywhere. Blog:

With these simple 3D prints and cable zip ties (2 for each chair), both of my office chairs are currently operational. I haven’t tested it out, but I believe that this inexpensive system would also work if 3D printed in PLA, using more cable zip ties.
