I use this product at home and for the money it is not that good I had another carpet saver that was better and I feel this will not last near as long as the other one.
[...] Much too thin. So chair remains in "holes" under rollers and does not easily roll on surface. Die-cut is lopsided. i.e. the first spike row on underneath is skewed and does not go completely from left to right side.
My chair cause divits in the mat after only sitting in the chair for 10 minutes. They have not come out. Everytime I sit down in the chair it caused more divits then you can't move your chair. I got frustrated and threw the thing out and purchased another one.
