Instructions were easy to figure out, and once everything was put together, the cats loved it and now use it every day. They nap on it, play with each other and use it as a perch to look out the window. GREAT value compared to the bigger stores like Petsmart or Petco. They want a ridiculous amount of money for much smaller kitty condos. We are very happy and so are the cats!! We just did NOT receive "surprise cat toy" that was supposed to come with the condo.
