I gave it 5 stars because of the high quality of the mat. Its very large something I had been looking for. The only bad point I had was that it wasn't in a roll when they delivered it and it was hard to maneuver especially for a disabled person and came in a mangled look. After it got flattened out it worked fine for the high quality wool run it was placed on. The price was much better than any other place I had seen it. I'd definitely tell a friend about it.
When I received the mat it was rolled up in a makeshift carton. It looked like a giant semi-transparent potato chip. It took a week with weights on it to smooth all the lumps. I'm using it now and it feels like I'm perched on a hill. My chair keeps wanting to roll down hill.
