Easy to put together tree even though the directions are only one odd sheet of paper.  The cat tree seems sturdy.  I have a 15lbs cat that had a 6ft cat tree before I moved across the country.  It was important that I found a new one for him that he fit in.  The only down side to this tree is that the tunnel that is open on both ends isn't very long.  He can't get in it and lay down.  Other than that it is great and he already loves it.

Pros: Great value
