I received the mat promptly in good condition. Laid it out overnight to flatten. It is a bit bigger than my previous one which is good. It is a bit thin which may affect durability but appears well made. I would recommend it.
The pad was rated for medium carpet pile. My Carpet is medium. The pad walks the prior pad that I had never had to be realigned this one requires it about every 4 days.
We got this all rolled up but we laid it down and put a dictionary on one corner plus the desk chair and it laid flat right away. Durable and works great.
