So everything requires maintenance, well everything man-made anyways. My office chair squeaks, it didn’t when I first got it, but over time, it started to. I honestly didn’t notice until the other night when I did my usual get up in the middle of the night and get some work done, alone and the only one awake I heard it, and then I couldn’t hear anything else. I sprayed, lubed, and tightened but it still squeaked. So last night I took it into the garage and overdosed it with WD-40, that did the trick, and no squeak today. I guess the moral is to keep trying to fix the things you don’t like, you’ll eventually get it…
