Is your SIHOO M18 chair creaking, sinking, or just not feeling like it used to? Don’t worry—most issues are totally fixable with the right tools and a little guidance. This guide will help you identify and repair common problems so you can get back to sitting in comfort.
Quick Fix to Common SIHOO M18 Problems
Sinking Seat: This usually means the gas lift cylinder has worn out. Replacing it restores height adjustment. You can find a suitable gas lift cylinder here.
Wobbly Armrests: Over time, armrest screws can loosen or brackets may crack. Tighten bolts or replace worn parts. Check out replacement armrests here.
Unstable Base or Wheels: If your chair wobbles or wheels don’t roll smoothly, inspect the base and casters for damage. Swap them out with new replacement casters here.
Backrest Tilt Not Working: This can happen if the tilt mechanism is jammed or broken. Lubricate the joints first; if that fails, replace the mechanism. Try a new tilt mechanism here.
Loose or Noisy Components: Screws and bolts may come loose over time, causing rattling sounds. Periodically tighten all fasteners using a good screwdriver set like this.
Worn Seat Cushion: If the chair feels flat and uncomfortable, the cushion may be compressed. Consider replacing the pad or adding a memory foam seat cushion.
