We have had our chair mat for less than two weeks and already there are indentations in the mat where the chair sits at our computer site. Because of it the chair barely rolls and it involves getting up and physically moving the chair over these intents when getting closer to the computer is necessary. It has been a huge disappointment.
Purchased this along w/a taster chair & it was just what we needed. This is made of THICK plastic that STAYS in place!!! My hubby is a BIG guy & he can roll his chair across it as if he were in the office rolling across the thin office carpet. I’m a believer in reviews. Take my word & BUY this!!! I placed it over the carpet in the basement it rolls very well!!
