I purchased this for my 2 1/2 year old grandson who loves to climb and to slide.  I wanted something different - also something that would appeal to his older (9 year old) cousins.  I thought it would take him awhile to master the climbing, but he succeeded in makng it to the top within the first hour of use.  He loves climbing on it and hiding in the "cave".  The older boys are having fun with it as well.  Assembly was not as difficult as expected - except for attaching the upper part of the cargo nets.  I expect this will get alot of use in the next 6 or 7 years.
