Purchased this to protect my Berber carpet. Works just as well as the pricey variation. I have purchased a much more expensive model and it didn't look as good lay as flat or resist chair roller divots as well as this one. I am very pleased with my purchase and may be replacing the expensive one as well.
The product is too thin to adequately stay flat on our home's low height carpet. The sticker adhesive is very difficult to remove and left a very sticky surface even after repeated cleaning attempts.
After much looking - and waiting - this mat finally makes the grade. I can't believe there are so many mats that claim to be for pile carpet which would barely be useable on berber. My chair wheels with my 225 lbs atop don't sink into the carpet through this mat. The points on the bottom are kind to the flesh as well.
