After seeing the damage done to hardwood floors without having a chairmat I wanted a chairmat as soon as my new hardwood floor was installed. This chairmat does protect my floor where my chair sits but it does slide around somewhat.
I have a recording console with a number of units that require varying adjustments when doing a project. I can easily move to different positions in my roller chair with no difficulty. The size is just right and the quality of the mat is excellent. I would recommend it highly. It's a real buy.
I bought this chairmat to protect my new hardwood floor in my study. After seeing the destruction that was done to my old floor without having a chairmat I knew I wanted a chairmat to cover all possible areas that my chair would roll on. The size and shape is perfect for my computer area.
