I got this about 3 weeks ago.  It arrived very quickly and I assembled it by myself in less than 20 mins.  The instructions are pictures only.  

Others that have reviewed this complained that the sides of the houses are cardboard, but mine actually has very thin press board sides which are plenty sturdy.  

The quality of this is very good.  My male cat LOVES this.  He is a climber and he literally leaps from section to section and sleeps in the top cat beds.

You would pay 3 times this price for equal quality in a pet store.  Highly recommend!
