Very well built!  The very top piece is not attached, but the screws are already in place, just center the last cubby over the center of the post and screw in place.  I ordered the light colored one.  We have three rescues, each has their own perch.  

I love shopping Wayfair.  Prices are competitive with stores like:  TJ Maxx, Homegoods, Marshall's and Tuesday Morning.  The free shipping option wins me over, too!
