Desk Chair

That makes this grinding / crunching noise when you sit down or move. I tried WD40 and grease, but it still works. It is very annoying and loud. The seat is only 2 months old and has done so since I bought it! Help! It is not an "ass" problem. My kids sit on and it does not matter. Are you sure that there is a problem in the butt instead of a chair problem? back for a second attempt to tighten loose screws. and get some wafers / rings.i think they will help. Dude, wf.If it is because you bought it, why do not you back that the b | tch long ago! Try Vasoline.
