[...]my cat tree in the form of a huge, heavy box looked daunting BUT assembly was actually VERY EASY and QUICK!  Good materials and smart design aided by simple and concise instructions made for an affordable, fast, "pain free", sturdy end result-  a "Cat Magnet"  >^..^<  -a successful purchase.  :)~Like other reviewers mentioned my cat does not use the hammock but it IS useful for storing his toys....
