Very simple pad used under a 5 x 7 rug in our tiled entryway. Didn't want or need a heavier pad, just something that would prevent it from slipping and sliding on the tiles. This fits the bill perfectly. Does not raise the rug so high that there is a trip hazard, but prevents movement of the rug itself. From prior reviews we were expecting an issue with initial odor, and there was some when we opened the package, but it dissipated within one hour, so it was not a problem for us. Good value, and would recommend to others purchasing.
