My carpet isn’t that flat so the mat tends to curl up on the sides when sitting in the chair. I don’t like the 2 tabs on the end of it. I realize it is for hanging up in the store but they should be removable. But it does serve the purpose of protecting my carpet.
I have purchased several floor mats in the past from Staples. This one is much softer than the others and the wheels from may chair make a dent in the mat.
This rubber chair met is a good light-use purpose for its price. The met is for my wife's rolling chair under the carpeted sewing table. The most economic chair rubber met around good buy for the price.
