Why Does My Chair Keep Going Down?

A desk chair sink due to a basic reason: its lift cylinder is malfunctioning. The chair cylinder links the chair base to your seat and lets you adjust your chair’s height.

Within the cylinder is Nitrogen. The gas allows your chair to change height when you draw the chair’s lever.

The cylinder’s seal wears out with extended usage, allowing Nitrogen to escape. That’s what causes the chair to sink as there isn’t adequate gas to maintain it up.

Hold a ruler across the cylinder to estimate its diameter. You can also calculate the diameter using the circumference for precise measurements, though not necessary. Alternatively, use calipers.
