I guess my carpet is Med pile b/c this mat gets dented by my office chair wheels and it keeps on moving towards the right and 'bumping' into my desk and denting. I literally have to move it back twice a day. It might be perfect for a low pile carpet but I wanted to write this so if you're not sure if yours is low it probably isn't and you'll be disappointed with this mat.
I have what I was told os medium pile carpet.I have an office chair purchased at Staples a year or so ago. The mat slips and every few days I push it off yhe mat so I can move the mat back in place and not curling against my desk leg.and then placing this heavy chair back on the mat. I also have depressions on the mat from the casters. the mat shifts I suppose because of movement of the chair.
