This chair is amazing, I've used it with countless kiddos that I've nannied so when I had my own baby I knew I had to buy this high chair for him too. I found mine at a good price secondhand, since brand new it is incredibly expensive. I was so excited, but when we got home and I got the chair set up I realized that they have newer infant seats that have the back support, and that the older chairs don't accomodate to this new and improved feature for our little ones. I'm really upset that this wasn't more conveniently advertised when I was researching buying this high chair. Now I'm going to have to sell my current chair, and repurchase a newer one, because I really want my little one to have the comfort and support that the infant back support chairs provide while babies are young, and still getting used to sitting upright on their own.
