This is the second same type of product that I ordered 6 mos. ago and I am hoping that this time it will last more than 6 months. Why did I purchased this same type of floor mat again? Because it was my only choice and our major office buying account is with Staples. Overall we love Staples and we are keeping the faith.
It was a good choice for me. The price was perfect. It does move some after using it for awhile so you have to readjust it periodacaly. Over-all I am happy with this product.
Currently have mat on top of carpet. Chair's rollers tend to sink into the mat quickly so rolling can be difficult. It does protect the carpet (which was the goal). That said I'll probably invest in something a little better/thicker next time around.
I use this for my computer chair which I use about 3 hours per day. The mat protects the carpet and doesn't slide around. The main con about this product is that it becomes indented from the wheels.
