My computer (desk) chair won't lean back. Is there a solution?
Yes, and it's a simple solution too. On the right side, you should find a flat little handle. Pull out on that and you can then lean back in your chair.
* This is proof what a blonde at heart Shirley is. The grandkids had been playing and spinning in her chair. Then it wouldn't lean back. She used it for months like that before discovering how to "fix" it. LOL
