An easy, cheap, and elegant way to prevent damage to hardwood flooring by using these casters. I use it on my Herman Miller Aeron chair and have had zero issues. The gliding is smooth and feels solid. This is WAY better than the stock plastic cheap wheels that come with a $1500 office chair and this solution is much cheaper than upgrading.
