Unrolling this from its package is not that hard. Use my method: Stand on the outside edge and side without the carpet spikes, with the main roll on the bottom, and use your weight to hold down as you lift up on the outside to unroll (with the pre-formed curvature downward), and work your way forward. Set a chair on it for a day. It'll flatten out over night. The Mat is awesome, I have no issues!

Great price on this mat, fit perfectly in the area I needed it to. As for the issues people are having flattening the mat - I definitely had issues getting it initially flat but after placing some heavy books on all four corners and in the center it was fine to move after 12 hours. This mat is performing just as well as another mat I've purchased from Staples, but was a lot cheaper for the size. Would definitely consider buying from here again if I need another mat.

Ok it does the job but getting it ready is a pain. I had it for 4 days under various items in the panty and a 2x 12packs of cola at opposit ends and still isn't flat yet

Thinner than average mat, chair very difficult to move on the mat

this works well with carpet

A little undecided, it is thinner than I had hoped.
