Bests & Worsts Reviews from Amazon

I have been using rubber no slide pads under my rugs but it was like walking on a flat hard surface. I had never used a felt like pad before. It arrived in a box rolled up but relaxed quite easily after being spread out on the floor. I ordered the 1/2 inch and it measures exactly 1/2 inch. It is a synthetic felted mat. I did a "burn test" and it is synthetic. It has a scrim (smooth, shiny side) and a softer side. I placed the softer side next to the floor because it seemed to grab and not slide in this position. I placed my rug on the pad and drew around. I then measured 2 inches in and drew another line for my cut line. I used a board and a carpet knife with a new blade to cut the carpet pad. I placed the board under the cut line and the blade slid through it very easily and continued working my way around the pad. I only had to cut 2 sides. I recommend cutting the pad 1-2 inches smaller than the rug. The corners of my rug are in the room's traffic pattern so I cut a small triangle of carpet tape and secured each corner just in case the corners flipped up when the kids came through the room. I am thrilled with the cushiony feel of the rug with this pad and I just love taking off my shoes and letting my toes walk on this soft cushioned surface. This pad makes my moderately price rug feel like a very expensive one! I am going to buy this pad for the rest of the rugs in my home!
