I'm getting some cushion floor laid in a study. I went for a more expensive one which is a lot thicker than the cheaper ones. The guy at the shop said that if I used a chair in the office it would leave indents. I have cushion floor in my kitchen with no problems with my table and chairs. Just wondering if there is anything I can use to prevent any indents using a chair with wheels? Seems kind of pointless having cushion floor if you can use a bleeding chair on it!
