The cat tree arrived when expected; it was packaged well and efficiently and took only one hour to assemble. Another buyer had suggested to lay out all the parts before assembling and this was good advice since the sisal covered poles looked very much alike, varying only in height. I was very pleased by the quality of the materials - no particle board, instead solid wood. The carpet is attached well and the way the platforms connect to the verticals helps to stabilize the unit. So far my cats haven't ventured higher than the first "condo", though I'm sure this will change. Very pleased with this item.
