the mat came wrapped with the stickiest tape imaginable. I could not remove the residual glue from the tape even using paint thinner. the mat still allows the chair rollers to imbed into the mat. Not really happy with my purchase.
First of all the mat was not delivered when it was supposed to be and it finally took a phone call to have it re-shipped. Usually chair mats are delivered in a flat box...this mat was delivered folded-up so it did not lay flat. Right now we have some heavy boxes on it trying to flatten it out. Seems to be the correct mat though.
