Very happy with the purchase and it is thicker than others I hade previously bought. I anticipate this one outlasting all others! Stays in place and chair rolls nicely. I've only had it for a week so time will tell.
Historically floor mats have been very difficult for me to handle because the nubs meant to hold the mat in place are usually pin-point sharp. Not so this piece. The nubs are effective; yet the nubs are blunted slightly preventing sharp pain and discomfort. Good job. And Staples delivered this piece exactly on time.
