Only con is if I sit for too long in one spot the chair has a tendency to sink into the mat. Indentions are left in the mat and some are becoming permenent
This arrived today in a HUGE box rolled up. The contruction is not an issue if it was shipped flat. As it stands now the edges are curled upward (I'm constantly tripping over it) it's buckled all over the place so that a chair does not roll easily on it and did I mention it came rolled up? Terrible shipping. This should have been shipped flat like the last one I ordered nearly eight years ago. That one lasted a long time. I'm just about ready to throw it out if the plastic doesn't settle flat on the floor.
