Had it shipped to my house. Came home to find it all bent up and ready to fall of the porch. I realize that it's not an easy item to deal with but come-on.... I'm still putting weights on it a week later try to get it to flatten out. Shipper could have done better...
My old one about 13 years old was getting a lot of cracks from chair wheel pressure. This one seems sturdier. It was not difficult to place because my cabinet is on wheels so I moved it out of the way and then the wheels carried it easily over the mat. It is not showing any "dents". I use it daily at my sewing machine with desk chair on wheels for several hours at a time. I am very pleased. If I can get another 13 years that will be wonderful.
The floor mat works but not on household carpet. It is very soft and the chair leaves indents on the mat which makes it hard to move around on. Not sure that I would buy this again.
