Got the new scratching post today and the same structure. I was in 15 minutes finished by the guide is truly described. Qualitatively, it is okay. The sisal rope is a little bit so my little one has to scratch not all too much. The scratching post is also stable and does not wobble. What should be noted in any case is that this cat tree is more suitable for kittens, kittens or small cats. Big Cats / cat or Main Coons can use the scratching post does not guarantee be happy !! My cat is petite and so it fits into the cave. However, the deck board below it can not use because it is too large and the obrige hole and into the "hammock" it does not fit. For small cats really sufficient. For larger rather stay away.
