My chairs are white in color, metal, and cold on your bottom, so I was looking for something round, not heavily padded to fit the chairs. I purchased a few padded cushions, but they didn't fit so I had to send them back. I was so happy to come across these! I purchased the black chair pads and I think they fit perfectly and give just enough padding. They are made of texturized polypropylene, not cotton, but I'm not that picky.
I'm very happy with my purchase.
