I bought these chairs to go with a Skip Hop sit and play that converted into a table. They were taller than I was anticipating and my 1 12 yo has to climb on them to sit, but they are stable enough and she likes to sit in her own little chair to eat a snack or play at the table. The chair part is one piece and they come in an L shaped box. The only assembly required is attaching the metal legs, which was a little more confusing than I want to admit. There is only one way for them to attach properly so if it seems like nothing is lining up then you probably have to switch something around. Otherwise they are very cute and functional, easy to clean and great for kids!
