There was no information that it could not be used for padded carpet. A rolling 4 double wheel secretary chair makes identations in the mat which makes it harder to roll. I would never buy another one
I use this on carpet and it seems to not have enough thickness. I had it for only 3 days now and I am worried that it may get damaged from my chair's tires. There maybe a hole there soon. I will wait to see how it performs.
Great Price only[$]. Works as good as the pricier models. Was also rolled up so easy to transport in the car. No problems rolled flat on the berber carpet very easily.
