I wanted a stiffer mat this one came rolled up and it’s more flexible than I needed. It’s placed on carpet and “dents” where the chair rollers are. Since it was ordered on line and delivered I just kept it. Next time I go into the store and buy the right thing.
This mat was exactly what I was looking for to smooth my "ride" now that I'm working from home and have to get up and down from my chair many many times a day. Much easier on my back and it's barely visible. My only caveat is that it came rolled up (understandably) and after I removed the heavy-duty scotch tape holding it in a roll I have not been able to get rid of the tape's stickiness which sticks to my shoe every time I walk over it. I've tried a sponge with boiling water and many attempts with Goo-Gone to no avail!
