The chair mat is working well. The only reason that I did not give it 5 stars is because the chair rollers leave indentations on the mat. I weigh 118 pounds and my desk chair is a secretary chair with rollers so there is not a lot of weight. I would not purchase this for my husband who weighs 220 pounds and has a large office chair. The mat does not slide around on the carpet which is good. A big plus was there was no odor when the mat was new.
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.
