15 -20 min is all it took to assemble this monstrosity of kitty fun. The only tools needed came with it so that made it even easier. Within min of opening the box the cats started coming around sniffing and rubbing on the sisal supports. I didn't even get the top perches on all the way and they were climbing and tusseling over who got to go where. I have 8 cats and this is actually large enough for all of them. It is also very sturdy, which has been an issue with other cat trees we've had in the past. The cats say Thank You for our new CAT-TASTIC KITTY MANSION!
