Assembled the cat tower in no time.  Instructions were a little confusing in some places..maybe it was me, the reader being confused.  Our little kitty loves loves loves this cat tower!!!  It's exactly what we needed. Wish the cat perches were padded, but our kitty doesn't mind. He sleeps on top perch.  Works great in an apartment.  Doesn't take up too much space. Very sturdy.  Satisfied with the product and what we paid for it!
