Great rug pad, I found it much more convenient to have it delivered folded than rolled at full carpet size. It looked creased when I got it out, and at this thickness I thought it could be a problem- but actually as soon as I laid the carpet back over it, there was not any noticeable wrinkling at all. It had to be trimmed at the edge, but it was easy to tell where to cut (use the bottom grip pattern as a guide), and now the size is perfect, it doesn’t slide and it lays flat. Pretty good deal for the price, I would recommend it!
