A new entry into the category of travel seats, this is an inflatable, portable alternative for occasional use. If you need to strap three kids in a back seat and two are in regular car seats, you are going to want a BumbleBum for older child stuck in the middle. Testers really liked this unique booster seat but were very clear in their comments that this would probably not be considered a replacement for a regular booster seat. This is one of those "in a pinch" seats designed to bring on an airplane or when an extra child joins you for a drive. Very easy to inflate and deflate for packing in a suitcase if the need arises. The fun purple color was certainly appealing and the fact that it is easy to pass a center lap belt through the clips on the seat to hold it in place resulted in solid scores.
