My husband put it together in 4 days solo, he said the wood splits easily sonbe cautious of that. Cool play structure overall thoigh, but we did need lots of extra support throughout, as a mother, I did not feel comfortable having my kids inside without. Specifically the eagle nest seemed very instable without a large support beam underneath. Kids love it though, age 4 and 9 and is a good structure for their ages...we can definitely all fit inside and even have slumber parties when the weather is nice. Overall recommend but would also recommend adding the extra supports.
