The mat does not stay stable on top of the carpet. I had a sales rep. assist me and never was told that it was possibly for a thin carpet. Now every minute I need to straighten it (not kidding)…Truly disappointed…
Does what I want it to do which is protect the carpet and helps me roll easily. Very happy with purchase. Came on time too. the only reason for 4 instead of 5 stars is that it does seem to get dents in it from chair. I am only 125lbs so I don't think it is me. I don't care much about that but wanted to point it out in case someone does.
