An extremely large cat tree with many levels.  Construction seems sturdy (the box weighs a ton) and the fabric feels nice.  Assembly was fairly easy, no special tools needed, graphic instructions were reasonably clear.  I put it together in just a couple of hours, parts fit well. The cats seem to like it so far. They do not understand the hammock and top nest, but I think they will get it eventually.  Very reasonable price for a large tree.
