By description this mat was listed for being used on plush carpet but the chair wheels still sink into it. Also note that I'm 175 lbs. and with the chair approx. 200 so it's not like I'm a 250-300 lb. person. Not as bad a standard mat but this one is thicker but not thick enough to be used on plush carpet. I would not recommend this product for plush carpet.
Set up new office in my home needed a carpet mat to protect my chair and floor. Stop by my local Staples on Hwy 200 and SW 27th Ave Ocala. Didn't see any the manager came by ask could he help told him what I was looking for he check in the back. Thanks so much I was beginning to think these things didn't exist anymore. Thanks Again
