At this point it's serving more as a tripping hazard than anything else

This is a trip hazard

It is more of a tripping hazard now that it is still wavy under my office chair.

I put heavy books and heavy chairs on them for several days and they were still a little rolled on the edges (a major trip hazard) and have a bubble in the centers.

I put weights on it the other way over night and it is still curling at the corners causing trip hazards.

Takes a while to flatten out, but it was rolled and packed in such away that it curls into the carpet anyway, so not much of a trip hazard during the initial set up.
