This is an amazing backyard outdoor activity! I am home-bound so I can't go anywhere fun with my granddaughter. So she can't wait to come over to my house and climb her little heart out! My husband put the Skyward Summit together in about 3 1/2 hours, alone without help. It isn't difficult, you just need to spend about 30 minutes organizing the screws, bolts and parts into plastic bags first. This will make building the Summit easier. Before you build, plan the space where it will go. We live in Florida so put the Summit in a partially shady area so the plastic wouldn't absorb too much heat from direct sunlight. I haven't had to clean the Summit yet, but I think using a spray bottle with a gentle soapy mixture to spray on the Summit and then rinse off with a hose will do the trick!
