My chair was ripping the rug in my home office. Rather than replace the wheel I found it simpler to order this plastic rug. It works well my chair slides easily and I am happy with it. The price was right -- actually better by mail then I could find in the brick-and-morter store. It was a good purchase.
I use the mat on a linoleum fllor where I have a desk chair. It protects the floor and you don't really see the mat on the floor- so it fits my needs perfectly- better than expected.
