Our 5 month old is tall and although she is close to sitting up alone isn't quite there yet. She's getting too long for her baby bath tub and I needed some type of sling or seat she could sit in in the big bath tub. This works perfect. I love that it folds up which is awesome when we go visit my parents a few states away. Only issue I have is that I don't think I would use it for a younger baby as the sides aren't very high and even when fully reclined it doesn't sit back that much.
