Multi-function efficiency is at its best with the Mutsy 4 Rider Babysitter Chassis. This sturdy and lightweight frame is engineered to transform either your Mutsy Seat or your Carrycot into a soothing baby rocker that helps your restless little one drift gently off to sleep. You can also stabilize it with two simple, flip-down legs and use it as a stationary seat for feeding or playing with your baby. Combine it with the Dinner Tray for maximum convenience!
