The base of my office chair is cracked. Can I replace just the base, and how do I do it?
Yes, you can usually replace just the base. The key is matching the gas cylinder type. Here's the basic process:
- Remove the Old Base: Turn the chair upside down. You may need to tap the cylinder out of the base socket with a rubber mallet.
- Match the New Base: Ensure the new base has the same stem hole size (usually 11mm or 22mm) as your chair's gas cylinder.
- Install: Push the new base firmly onto the gas cylinder until you hear a click or it's fully seated. Test before using.
