I purchased this set to place in my yard for my 2-yr. old grandson...my first grandchild!  He is able to climb the steps and go down the slide without assistance...just a close and watchful eye!  I temporarily replaced one of the swings for a toddler swing until he is old enough to use the strap swing, which shouldn't be too long!  I lay a throw rug in the little playhouse when he wants to go in to play or lie down.  I have another grandchild on the way, so I look forward to using it for several years.  My two sons were able to put it together without any problem.
