Baby Einstein Ocean Explorers Sea of Support is a 2-in-1 sit-up floor seat. It is very simple to put together and very easy to clean. This chair is awesome because the seat heights adjust to grow with your baby and supports your baby while they are learning to sit up. The seat also folds flat for easy storage and travel (love this). There are two linkable toys included. The fabric seat is very soft and comfortable and I love that it goes under the seat for babies cute little feet. I would highly recommend this seat!
