We just bought light colored new area rug and my desk chair wheels were going to make marks and dents. This light color blended in and my chair rolls easily on it. I used some cheap rubbery backing to lay down underneath so it won't slide around.
I use a three legged stool at my desk in our family/breakfast room and it had already started leaving scratches on my wood floors. We have walnut floors and I did not want to use the standard clear plastic but I needed something to keep the stool from scratching my floors. This chair mat blends right in with my floors and keeps the stool from scratching the floors. My desk is a small rolled top and the three foot by four foot is perfect to slide under my desk all the way to the wall and extend out enough to protect my floors. Glad I was able to find this at Staples.
This is a nice heavy pad for wood or bare floors. Only comes in two colors though light oak or walnut. Would be nice to have a mid-color choice or clear. I can't honestly comment on reliability or quality because this is the first one I bought and it's still new!
