The sofa is sturdy and very cleverly built.  It comes with the legs off.  What surprised me was it folds for shipping and came in a smaller box than I expected.  You get it out of the box, unzip a pouch under the sofa that contains the legs and other parts, unfold the sofa upside down, attach the legs and simply flip it over.  You are done. If you ever need to move with it or store it, just take the legs off, fold it in half and its so much easier to move than a regular sofa. It converts into a twin size sleeping space in seconds.  I'm extremely pleased with it.  It's going in my father-in-law's new trailer (he's 88 and doing well but we needed him out of this old two story house with the steep old stairs) and will make wonderful seating and an extra sleeping space.
