I bought the 6' square version of this rug and the recommended rug pad from the same manufacturer. The rug pad came first by a few days, which was fine; I put it in the spot the rug would go, anticipating I would roll the rug out on it and be done. No such luck. The pad is 3" larger in one direction and 1" larger in the other. I'll trim the pad, but it's thick and it's going to be a pain to do. That cost the rug a star.

On the plus side - I did not encounter the problems others reported with it lying flat. I opened it the day it arrived and rolled it out, and the curled edges settled by the second day. The rug itself is what I expected. The red is more dominant in the square version, but that's fine. It suits the small library room that I put it in.
