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)
It is too thin!! It does not stay in place! And when anything is set on it - deep indentations occur. I am sad that I purchased it . Hopefully you can suggest something stronger and thicker- like the one I purchased from you many years ago- which was wonderful.
