A protective case for an electronic device includes a chassis, a back portion, and an internal suspension system. The chassis includes a cavity having inner surfaces. The back portion is attached to the chassis and adjacent to a back surface of the electronic device when the electronic device is installed in the protective case. The internal suspension system is positioned in the cavity and attached to the inner surfaces of the chassis and to the back portion of the protective case. The internal suspension system includes multiple cushion portions. One of the cushion portions contacts part of the back surface of the electronic device. The internal suspension system protects the installed electronic device from external forces and provides an air gap between the protective case and a back surface of the installed electronic device.
