This very affordable chair has a vibrating base (get biggest batteries!), toy bar and is easy to bounce with hand or, more importantly, foot. This becomes invaluable when baby is having a fretful evening (which most do between 3 and 12 weeks) and you'd like to eat any sort of evening meal. Our daughter really likes it and has often fallen asleep in the chair while being bounced, even when overtired and quite grouchy. I'm sure there are other chairs that do the bouncing for you or have more features, but considering how long a child will use this for and how many other expenses parents have, I would highly recommend this product on price and durability.
