This had to be one of the easiest cat trees to put together.  We had it up in less than half an hour, and it is certainly sturdy.  We put it up in our dining room, with a good view out the window, and now all of our cats have a place to sit in the sun and see out.  No more fighting over the window sills!  They love the scratching posts that are built in; the little condo space is very popular, and even our older cats find it easy to get all the way to the top pedestal.  They even love the little ball toy that was included.  The covering material is very soft, and the piece is attractive overall.  We love it, and rarely ever see this tree without at least one cat on it!
