The City Select Carrycot Conversion Kit contains plush fabric and a support bracket that converts the City Select's single seat into a carrycot in a few simple steps. Simply remove the fabric seat of the stroller and snap the carrycot fabric onto the same frame. 2 year guarantee included. Please note: The single seat is needed to complete the carrycot conversion. To use the carrycot in double capacity mode, the second seat for the stroller will need to be purchased in advance.
