I got this lovely highchair from my in-laws. It was in great condition although it was a little rickety and needed some screws replaced.
I decided to paint it black so it would match our dining room furniture. It was really pretty easy. I just used spray cans of primer, black semi-gloss paint, and a few coats of clear to seal it. I have not attached the tray yet, and I think I like it as it is for now anyway. It goes right up against our table and now Levi has his own chair and doesn't need that clunky plastic booster chair he was using.
