Assembly is a breeze. Real carpet...yay! No faux material here. Solid wood posts-no cardboard tubes. Screw plates are set into the wood so poles won't in time get wobble. Base could be a bit bigger. My 11 pounder gave it a nasty wobble. I am highly concerned with the way the carpet has been "adhered" to the wood. On poles and the 3 round perches. I will be watching to see if these seams stay tight. Loving the bigger round sided perches. My cats love it. My little Siamese was hanging out in one of the round perches before I even got it put together. Only the top perch is covered in carpet on the bottom. Lots of hanging plastic threads too.  I hope the carpet doesn't start to pull away. I am thinking of ordering at least one more if it holds up. Love the wood quality, real carpet and wood weight.
