My cat about lost her mind over this! She absolutely LOVES it! She sleeps on it, she plays on it, she escapes my 4 dogs on it... its below a skylight, and when the sun is hitting that top platform, she loves to sunbath there for hours. It took a while to assemble, but the directions were very clear and the parts all have a sticker with a letter, then theres a diagram showing the lettered pieces and what they attach to. Great price for a very substantial cat tree!
