It was easy to assemble.  It is wobbly and the hammock is not as large as the picture shows.  We have a  16 pound cat and he does not fit in the hammock.  The perch is the right height for him to look out the window, which is his favorite activity! The base needs to be larger. We are planning on using brackets to fasten it to the wall so it will not fall over when he jumps down.
