I purchased a returned item for approximately half the cost of Wayfairs normal list price.  Product arrived via FedEx in two days, and was in new unused condition with no missing parts.  It appearantly had never been taken out of the box before being returned for unknown reasons.  The instructions are very poor, consisting of a single black and white line drawing with no part numbers.  Use the color picture on the side of the box to assist in determining where to place the panels.  Assembly time was three hours.  My cats like to be up high, so I placed the bed that is shown on the middle right side on top of the upper house on the back right hand corner instead.  The configuration can be changed as desired.  This tree looks very nice and is sturdy, but is large and fairly heavy at 90 lbs so keep that in mind when deciding what to buy.
