This came well packed and every piece accounted for - including all the tools and hardware you need to assemble it. Although this is a huge tree, assembling it was pretty darn easy. I chose this one because it offers a lot of levels and multiple means for multiple cats to get up and down, helping minimize territorial disputes that happen with most vertical cat trees that only have one way up and down. The most fun was watching my 5 cats "help" me get it together. They were on every level and every bed and hammock as it went together. They love it! My three-legged cat was the first on top. Reasonable price for such a large cat tree. No regrets!
