I have a Costco task chair with mesh seat and back that I've loved. However, spending more time in the chair with covid the last year, I was yearning for a headrest. I didn't want to upgrade the whole chair, so looked for options. This was a risk, but worked out great. I drilled a couple 1/4 holes in the frame, and used some hardware I had handy around the house. I think riv-nuts or nut-serts would work well in this application as well. I've been very happy with the results.
