Honestly this mat is pretty terrible. The problem is that the material is too soft so after a few moments your chair’s casters will sink into divots that you’ll have to roll out of when you try to move (yes I’m a fairly normal size person; 6’1” 220)
Mat seems to be very sturdy. Thought it might be a little large but turned out to be exact fit for where I needed it. With the $25 off it was a great buy.
So far it's working out like the one we had to replace that one lasted a couple of years but being plastic plastic does have a shelf life and gets brittle and cracks so if I get the same time with this one I will be happy
