I purchased two of these chairmats for a home office. Previous chairmats cracked after a relatively short time; these chairmats are much thicker than those cracked ones and I hope will last much longer. Only time will tell and I am writing this review right after receiving the chairmats.
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.
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
