Relatively easy to assemble, but I did fall off backwards on my first attempt to actually sit on it! 2nd attempt went great, and I love it! the effectiveness was immediate, but I had order the seat cushion, my tailbone actually hurt after about five minutes. now I can hunker down for 15-20 minutes with no problem! standing up from the hunker position has gone great, with no pain or strain at all! love the product!
