If you need a mat that helps you glide across the floor this product is the one. Reasonable price for the size. It fit like a glove under my desks. It was easy to carry to the car. Go purchase today.
I weigh 140 pounds the chair I use weighs about 15 to 20 - and I'm allowing for some additional weight just to be safe. Within 2 hours of putting this mat into use there are dents in the plastic so deep I cannot move the chair out of them. If I were a 6 foot 4 inch man weighing 250 pounds I could see this happening. I'm 5 foot 7 140 pounds. Absolute garbage - rolling chair can't roll on the mat due to weak bendable construction - perhaps this is a memory foam mat.
