We are so pleased with our Cat Tree.  I actually bought 2, one for us and one for my daughter.  She put hers together in a flash and my husband said it was a piece of cat.  When I got home it was up and ready.  It was really sturdy, which was an initial concern of mine in making the choice to pick the 57".  We have 2 cats, Pele active and Hobbs not so active.  Pele was in it in a flash, we were concerned about Hobbs.  After about a week Hobbs was diggin his new digs.  I would recommend to anyone.  The cost of the Cat Tree was also a great value, we shopped around and we couldn't beat the price especially with the free return policy it was a great investment.  We're keeping them!
