I have a rolling office chair and a hardwood floor. This plastic mat fits right between the two. I don’t notice any difference in how my chair moves so there’s that.
I am using the mat in my home office where I had no mat before. It allows my chair to move in a way to accommodate multiple computer screens. This increases the amount of work I can accomplish in a given amount of time.
Quality is good for the price. Chair rolls well. I knew that I needed more thickness due to the padding beneath the carpet. This works well for now although it will not be a long term fix.
