Finding this mat at Staples is as easy and the staff was very helpful. I took it home placed it under my desk/chair and now I am moving freely around my desk!
This mat is too thin. The chair wheels create an indentation that you really need to work at to get out of. It might work for a child someone very light.
This is my second desk mat and I am sure it will hold up as well as the first one. I have carpeted floors in my apt. and this is a necessity. I am pleased with the amount of use it gets. I sit at my desk more than on my chair or sofa.
