The quality isn't there. It is so much thinner that my old one. It is so thin that the rollers make indentations in the plastic. Very hard to roll the chair while sitting in it.
I needed this for work otherwise I’d return it. It was delivered folded in half with tons of crumpled areas. Had to use a hair dryer to get the large bits flattened. Chair mat moves around on hardwood floor. Make sure to move slowly.
