It's not sturdy at all; I'm going to replace it. My kid has muscular dystrophy, and this model is terrible for providing support for him. Be careful regarding what is soft or if you want something sturdy.  The back has very little support and is very saggy on the seats. If you want to read a book, this is not for you; if you want to take a nap - this is the model for you. It's very soft to chill out during the day.
