A stroller having a frame, a seat on the frame for receiving a child and a heating/cooling system operably coupled to the seat. The heating/cooling system includes a single heating and cooling element proximate the seat. A reversible compressor is operably coupled to the single heating and cooling element. A first coil operably coupled to the compressor. A reversible expansion valve is operably coupled to the first coil. The reversible expansion valve is operably coupled to the single heating and cooling element. A refrigerant circulates through the single heating and cooling element, reversible compressor, first coil and reversible expansion valve. The heating/cooling system provides a first operating configuration for cooling the seat by having the refrigerant within the single heating and cooling element absorb heat, and a second operating configuration for heating the seat by having the refrigerant within the single heating and cooling element dissipate heat.
