So easy!  Just give it a good "fluff" when first using it.  We have always had "real" trees, but it was getting to be a chore lugging it up stairs to set it up, and worse to take it back down for disposal.  This tree was very simple to set up, looked great, and was so easy to dismantle.  I am looking forward to setting it up early this year for maximum enjoyment.  Strongly recommend!
