Pproduct is great. Works well in protecting hardwood floors. Issue is that it slides making it necessary to periodically realign. In this day and age has to be a way of stopping movement.
I needed something to protect my old wood floor which was getting chewed up by my office chair wheels. This is great. I would have liked a plain square rather than with the bump-out on one side because my desk is a table style. It does slip a little bit but not bad. And it's been a durable mat that is doing the job of protecting my floor.
good size too thin chairs makes indentations on matt. The manufacturer has a a sticker on the matt that is almost impossible to remove. Once you remove it it leaves a nasty smudge
