So far so good. Only complaint is that I think the bottom base should be slightly larger for more stability. I have it on hardwood and in a corner to keep it stable, I cant imagine it in the middle of a wall on carpet or something. I have crazy cats that will jump and do gymnastics flips all over it and I dont think it would be able to withstand that kind of force. Also, its a little awkward for biggerless agile cats to be able to get to the top perch as they have to scale the tube part. 

Other than that, the carpet quality is great as is the sisal rope and color! Shipping was fast, and it was literally THE EASIEST assembly out anything I have EVER bought, and I am notorious for buying things that need assembly. There were 3 pieces that got screwed together (screws already in place just about placing the screws in the holes already pre-made on each piece. Most was already pre assembled in the large box)
