A protective case includes a chassis having sides and a back that define a cavity with an opening for an electronic device. The back has an inner back surface configured to be adjacent to a back surface of the installed electronic device. The protective case also includes a suspension system having a first cushion and a second cushion. The first cushion is configured to contact the back surface of the installed electronic device and to provide an air gap between the chassis and the back of the installed electronic device. The second cushion is configured to contact side surfaces of the installed electronic device and to contact a front surface of the installed electronic device to form a seal with the front surface of the installed electronic device.
