Chairs were easy to lock legs in place.  The cushions come with three velcro straps and two tie on bands so they don't slip on the lounge.  Cushions appear water resistant as the water beads up.  I would not leave them in the rain though.  The two that we bought are very comfy, sturdy and wide and look great on our pool deck.  The lounges are also comfy with just a towel.
