A cradle securely supports a mobile device with the display screen at an optimal viewing angle, while leaving virtually the entire front sides and back areas of the device open and exposed to ambient air for maximum heat dissipation. Structurally, the cradle can be carved out of a standard disposable coffee container, so that it can be inexpensively fabricated from a modified coffee container mold. The cradle material can be a light-weight plastic, such as styrofoam.
