It covers all the things a preschooler and toddler need in a backyard play area.  Swings, slide and a fort.  the slide has a edge around it's side so they don't fall off, and land on their feet on the bottom.  the swings sqeak really bad. Maybe WD-40 might help or it might be the warm climate here in Florida I'm not sure.  Here is the real stumper with this playcenter.  The manufactures recommend 3-6 but my son is 4 and he looks like he is going to out grow it in another year.  He's not big (34 pounds).    My 1 1/2 year old (20 pounds)goes up and down that slide 20 times, she just loves it.  The fort it great.  So I strongly disagree with the age recommendations.  I would recommend this play center for a younger age group.  My 1 1/2 year old loves opening the fort and closing the door.  It is wonderful watching your children have so much fun.
