Sits on the floor where I put it. Lies flat. Doesn't move. Protects the hardwood. It's everything I wanted it to be. If you want a chair mat that will do all the things a reasonable person expects a chair mat to do then this chair mat is an excellent choice.
The mat is fairly thin and it will 'dip' from my weight (I'm not over-weight) & chair. It can make rolling the chair on the map a bit of an effort. I don't have plush carpet but the mat still moves a little - not as much as my previous one.
This chair mat works perfect it is more durable looking than the old one and we had the old one for 6 years. So hoping to get 10 years out of this one.
This mat is good quality and performs well. This mat is medium thickness (mils) and is a very good value for the price. Thanks to Staples for the ability to compare the mil thickness of different mats and free next day delivery.
