I installed a basket last weekend, and used it in the car this week. It was great just for holding all sorts of odds and ends, not just food. Previously I'd been using a store-bought organizer which hung on the chair, and this is so much better. 'Fits in the middle of the backseat floor, where no one has their feet (tyke's are off the floor yet).
