Once constructed, it is very sturdy.  I was a little skeptical from the other reviews and had plans to shore up some spots, but this thing is solid.  Not a project for the faint of heart- it has many little pieces and will take 2-3 people multiple days to put together.  Worth it though because my daughter and I love it.  The kitchen its really cute and being up high is a thrill for her.  I love it because it doesn't have a huge footprint and it is styled in a way that fits in with a backyard that isn't 100% about the kids.  Those plastic playsets really don't fit my lifestyle.
