I can't get it to flatten, the edges are more worse, right now keeping books etc to help flatten. Description states "80% Wool and 20% synthetic", i felt like "80% synthetic and 20% wool". I bought 8x10 but the dimensions is not accurate. For the price i paid, the quality is not great. Its thin as well. I feel it will die on me after couple of months. I will update review if anything changes.
