This chair mat was not strong enough bear the weight of my wheeled desk chair. Indentations developed immediately Moving the chair across its surface is possible but difficult and annoying.
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.
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.
