Query: Wheels Fall Apart

I bought 2 of these chairs 4 years ago because they were on sale. I was very happy with them for the first year. They felt sturdy and well-made, easily rolled anywhere and I loved the sliding tray. After the first year we found that the wheels were falling apart -- on BOTH chairs. I kept putting them back together, like a puzzle, even tried gluing them back together. I've also been looking everywhere for replacement wheels that are more sturdy, but haven't found anything that fits. It wouldn't be worth it to have them replaced by the manufacturer because they would just send the same crappy wheels. It really is a shame because the rest of the chair is just perfect and sturdy. I would have given 5 stars if not for the wheels. My next goal is to see if I can buy wheels from a different manufacturer.
