I (30 year old female) put this together by mainly by myself. There were about 2 or 3 steps I needed my husbands help with. I didn’t time it but it took me three days on and off. Probably 10-12 hours total. Not hard just time consuming. Definitely make sure your area is level. Ours is on a slight slope and I’m going to need to add some timber to the bottom of one side to level it out. I give it four stars because it’s not super high quality but my 6 and 1 year old both really like it and it was a good price.
