The JOOVY Caboose Rear Seat accessory converts the rear bench seat of your Caboose stroller into a full-size seat in minutes. It easily installs onto the existing rear bench seat and stroller frame of your Caboose Graphite, Caboose Ultralight Graphite or Big Caboose Graphite stroller. The Caboose Rear Seat offers additional support and comfort for children too young to use the rear bench seat and the standing platform on their own. A child with a minimum age of 6 months and max weight of 45 lbs. can sit in the Caboose Rear Seat until they reach the point where they want to use the rear bench seat and the standing platform. The Caboose Rear Seat features a multi-position recline, 5-point harness, and it folds up with the stroller for convenience.
