Unfortunately I had to order a larger size as it didn't come in the size I needed, but I was able to cut it down to the correct size really easily. I'm using it under a rug in my front entrance and it holds the rug in place quite well. Without it the rug would slip around every time someone came in and out of the house, but with it underneath the rug, the rug only moves if I'm purposely trying to move it. Other people had commented on the smell of it when first opened but there was hardly any smell when I opened the packaging and I couldn't even notice a smell within minutes of it being put in place.
