This Cat Tree is solid, sturdy,well balanced and pleasing to the eye.  My cat loves it,  He watched the assembly process from start to finish, and as soon as it was complete, he was exploring every level.  His favorite spot is the very top perch.  He has a great view out of the window!  I am particularly pleased with the sturdiness of this cat tree.  My cat is rather large and very buff so his previous cat tree would wobble extensively when he'd jump from perch to perch...Not this one. It is very stable.  I am glad I purchased this cat tree for "Blackster".  He's very happy with it, too.
