I purchase a new office chair mat for my home office about every 2 years. Seems most mats begin cracking after about a year. I selected this mat because it was specifically designed for high pile carpet and reasonably priced The mat wasn't available in-store so I ordered online right from the store with the assistance of a very helpful sales associate. The order was shipped directly to my home for no extra charge. It arrived just 3 days later folded in a box. It's important to follow the enclosed unfolding instructions to avoid cracking the mat. This mat is considerably thicker than many of my earlier purchases and incorporates "carpet bars" rather than points to keep the mat from moving. The bars seem to be effective. So far the mat is working well. Time will tell.
