I like the ease of use of the tubside bath seat. It feels very snug and secure...there is no way it's going to tip over, unlike some other bath seats. The part that goes over the side of the tub helps to lock it firmly in place. And, it provides some cushion for mom or dad's elbows while they are giving baby a bath! This bath seat is not for newborns but it is great for older children. We used it for my daughter and it is holding up well with our son also. We started using it for them once they could sit comfortably on their own. My son is 18 months old and is still using it. He could sit in the tub on his own but seems to be more comfortable in the seat. I think it gives him a sense of security, and it does the same for me. Of course I'm right there, but this way I know he won't slip on his bottom and hit his head. My only complaint about this seat is that it is difficult to clean. The bottom is in two parts so that the over the tub part can be turned either way. Unfortunately, it is hard to get dry and sometimes mold builds up in the bottom. Ick.
