The chair mat was great but was not happy with the way it was shipped. The tape that was used to roll up the mat for shipping left tape glue on the chair mat. It was very hard to get off had to use goo-gone three times to get it all off the chair mat. Not very professional.
The mat works well as expected. The thickness was important to us as it will last longer than a previous mat. All in all I am very happy with this purchase.
this needs to be firmer stiff. i use it on carpet and it makes pits in the plastic so its hard to get the rollers out of the pits . it doesnt matter what u weigh. my granddaughter who is 70 lbs even made the chair sink into the flimsy plastic. sorry i bought this. husband will cut a sheet of plywood and attach it to the top. this is a piece of junk.
