I assembled it alone without you instructions fairly quickly. It was very easy. My toddler is a nervous climber and we had to start her slow. With how adjustable it is, it’s great for any aged or skill climber. She’s now climbing all over and asking for us to change it around for her. It’s super easy to reconfigure the structures. I bought a lounge chair pad so she can use the arch as a rocker as well and it fits perfect. When not in use we fold the triangle and tuck it and the board away leaving just the arch out all the time. Planning on throwing a blanket it on it for when she wants to make a fort. We love it!! It came super fast too! Had it within the week.
