I bought this non-slip stickers for the bath. And so I also equal to something buy good quality, I have decided on this rather expensive product. After I have placed in the bathtub (which is relatively simple, but you have always the foil with your fingernails laboriously abpuhlen) but I had to realize it was a comfortable sitting unfortunately not given and made the seat test. The edges hurt very much, and the surface is too rough to sit. So they get out of there and the search for an alternative to the bath mat goes on.
