I bought the new chair mat because mine was worn. This one does not do the job. My chair does not slide around on it at all. It sticks and I have to get out of my chair to move it from place to place. I have an L shape work station and it simply does not function. I would be better off just going without it and sliding on the carpet...
Width makes it easy to roll my chair to reach file cabinets. Not boxed at delivery so it was awkward to move to where it would be used. Needed a cart to move it.
Mat is of sturdy construction very clean rectangular design. Slides a bit on repeated movement could use tacky backing on one side to help resist sliding effects on hardwood floors.
