I ordered this last week. It came today and I had it assembled in very little time, 15 to 20 minutes. Within a half an hour of being up my cat was exploring it. She has now settled down for a nap on the highest point. I see this becoming her favourite spot. She is loving the fact she can now see out the window on the one side and out into the back yard. I find it of very good quality and sturdy. I also am quite happy with the price I paid since I luckily caught it on sale last week.I love it!
