Bests & Worsts Reviews from Amazon

I went to Staples and bought their best heavy weight vinyl chair mat , my carpet is plush with memory foam padding. Two things, the mat stank like chemicals ( that's the PVC ) and after 20 minutes in my chair the wheels made little craters in the mat so no more rolling. After much research I found that EVERY vinyl mat will have the harsh smell and no matter the thickness of the mat it will stretch and not be flat. The POLYCARBONATE mat is lightweight has no discernable odor and doesn't cause lil craters to form around my chairs wheels. In other words worth, every penny of the extra cost. The vinyl mat went back. The Cleartex Ultimat is just that ...the ultimate chair mat.
