“This is incredibly solid, made very well. We had a few friends to help unload it from the truck and took us about 30 minutes. Building it with three (and briefly ) four adults took us 2.5-3 hours. We had the extra foot of height added and strongly recommend, makes for a great interior fort space and great for many kids to climb, play pretend, hide out, eat their lunch, etc..they’ve loved it and we’ve been so happy to have friends and neighbor kids coming over to use as well. It’s big! Again, very solid—this will last for a very long time and feels solid enough for big adults to climb all over comfortably.”
