Floors may be slippery on floor!

The floor mat makes a good impression in terms of workmanship and color. Of course, does not mean transparent, that it is completely invisible, which is of course also be seen on the product image already that there is a color difference to the environment.

But what I find very critical - and therefore only 2 stars - is the grip!

Quote "The floor mats were tested for their suitability for castor chairs and traction in accordance with DIN EN 425 / 02.08. They are also equipped with an anti-slip coating to increase the traction (in accordance with DIN EN 13287). [...] Ideal for hard and smooth flooring such as wood, parquet, ... "

For me It lies on a parquet floor. Now if you happen to occur to the rear end of the mat while walking through the room, the mat slipped quickly away. It is a literally pulled the ground from under their feet, and this has led on several occasions to near-falls. I feel that as a high-grade security risk! From an elevated grip I do not want to talk, it presents itself to me even the question of how much worse it could ever be even without the anti-slip coating here. An additional fixing by means of transparent double-sided tape on the floor is strongly advisable!
