Office Chair Sinking Stopper - (Vitra Physix)

thingiverse

I couldn't stand my office chair slowly sinking over the course of about 40 minutes, so I decided to take matters into my own hands and design a simple solution using 3D printing technology. This nifty device clips onto the chair with ease and holds it firmly in place - although, I must admit, it's a bit tricky to remove once it's been securely fastened. The height of the adjustment is precisely set for optimal comfort on my Vitra Physix chair when paired with standard-height sitting desks. The adjustable lock itself stands at 5 inches tall.
