Kid-Sit is a neat stroller wheel board and seat all-in-one, which attaches to the rear of a most strollers. The Kid-Sit has a refreshing design, is very user-friendly and great fun for toddlers. They now have the choice of standing or sitting when out and about with their baby sibling in the stroller -- no more tired legs standing on traditional wheeled boards. The Kid-Sit enables your second child to ride along easily, greatly increasing your mobility. The Kid-Sit fits strollers with a horizontal rear axle bar, no matter what diameter. The board rests on the rear axle and is securely attached to the stroller by user-friendly "zip" straps. The Kid-Sit Adaptor Kit (available separately) allows fitting to certain strollers that have no rear axle bar. The seat element is hooked into the board with one simple "click". The board can also be used without the seat, and it can be hooked up against the back of the stroller when not in use. It is suitable for children aged approximately 18 months to 4 years old with a maximum weight of 18 kg (40 lbs).
