The road I was extremely thin and already had rubber on the bottom, so I was looking for a rug pad mainly for comfort. I was looking at other rug pads about a half inch thick or so, but looking at people's photos, it looked like the rugs were just floating because of the how thick those pads were. I came across this pad that was 1/4" thick and I figured that would be ideal. After putting it down under my rug, it is definitely very non slip on the flooring I have, and it gave a good thick rug feel under my feet. It's exactly what I was looking for. It comes folded in the box, so there are some fold lines that need to relax, but not anything majorly creased. There was also no bad smells that came from it. I would definitely recommend this pad for anyone looking to have a thicker feeling rug or looking for their rug to not move around on the floor.
