I purchased this to replace one that I have had for 20+ years that had cracked in numerous spots. This appears to be exactly the same as the one replaced so hopefully it lasts as long. It does indent where the wheels are and I have to push to get it out of the dents but I don't roll around a lot. I just swivel my chair to get out. The chair basically remains in the same position. So this works for me. If you roll around you may find this annoying. I do not find that it moves around like some other reviewers have stated. The delivery was fast (received the day after I ordered it). It also came flat which was great. The only issue I had was there was a lot if tape stuck to it holding on the shipping label the carrier label the purchase receipt bar code etc.
This mat is fine for what I need it for to keep my office chair running smooth and protect my rug. It is not very thick plastic so I’ll be interested to see how many years it will last but because of the price I could buy three before I would pay the price of the more expensive priced thicker mats so that’s worth it to me!
