This mat is too "light weight" for my purpose sitting on a fairly plush carpet. It is smooth on both sides so slides around and bunches up where I anchored it under the leg of my desk. My mistake.
This mat may work well when placed on a hard floor. I am using it on a low pile carpet and the casters on my desk chair sink into this very soft mat to the point where my chair is difficult to move.
Great for a quick home office set up for remote work. At this price point it's not thick enough to handle hours of chair activity without movement so chair wheel indentions are expected.
Plastic mat to allow office chair to roll on rugs was delivered in 1 day and is great. Not as thick and heavy duty as my last one but should do the job.
