A stroller includes a frame, a handle, a plurality of support legs, a wheel attached to a lower end of each support leg, and a seat attached to the frame. The seat includes an internal Peltier device for selectively heating or cooling the seat. The Peltier device is powered via an onboard battery installed in an electronics housing that includes multiple USB ports. A blanket is removably secured to the seat via one or more fasteners. A processor in the electronics housing performs a method that includes activating the Peltier device to bring the seat to a preset temperature, receiving a temperature setting for the Peltier device from a temperature control button disposed on the handle, detecting a current temperature of an area within the seat, and if the current temperature of the area within the seat is greater than a threshold safe upper temperature, then deactivating the Peltier device.
