Would not buy again and thinking about returning the mats. They are not thick enough and I am using them on very short pile commercial carpet. The chair is leaving permanent dents in the plastic when I sit on it and I am not overweight whatsoever. My old mats that were replaced by these were in better shape after 10 years than this new set only being 10 days old.
Currently have mat on top of carpet. Chair's rollers tend to sink into the mat quickly so rolling can be difficult. It does protect the carpet (which was the goal). That said I'll probably invest in something a little better/thicker next time around.
I use this for my computer chair which I use about 3 hours per day. The mat protects the carpet and doesn't slide around. The main con about this product is that it becomes indented from the wheels.
It was a good choice for me. The price was perfect. It does move some after using it for awhile so you have to readjust it periodacaly. Over-all I am happy with this product.
Comes with strange not professional label. Pricelene for all line of mats is overpriced for about 300%.Hardness for mat 36x48 for lowcarpet priced [$] is not acceptable at all. Fake product.You have to review your price policy to sell good quality products for reasonable low prices.
