I would recommend anyone buying this put in warmest room in your home, or even outside in sunshione to get it to go flat

I followed the instructions on the box and left the map out for a couple of days in a warm room

After a few days in a warm room, it was very flat.

It needs to be at room temp or warm but will flatten out quickly.

I did appreciate the instructions in the box explaining that you have to be VERY patient waiting for this to happen, because it took 3 full days for it to soften up enough to spread out even in a fairly warm room

What I expected, pretty decent size for my L shape desk, you have enough room to back up, I flipped it upside down
