About a year or so. It was rolled up for 2-3 months. I managed to flatten it out for the most part with some heavy things on it for a few days. It really does work great though. I have a bit of a hand injury at the moment so I have been downstairs putting every night.
I ended up not getting the plastic that goes around the edges, because #1, it was $40 extra, and #2, I feel like I could make them for much less. Should have it late next week.
