The perch comes unassembled, but assembly is easy.   The items is pretty cheaply made, there is no padding.  The carpeted "bed" sections are hard and you can feel glue or whatever is holding it all together in various spots.   I found I needed to add some soft bedding to those areas.  Quite honestly, you could find a better and more comfortable cat tree in one of the various pet stores locally.  I'm not saying this one is that bad, it's just not that great either.
