The Sony ProFeel Pro (1986) monitor, commonly known as the Sony Cube, represents a high point in the developmental history of monitor technology and product design. This monitor incorporated the bright high-quality Trinitron screen (the brand name for a product line of aperture grill-based CRT screens) that had been developed during the 1960s, and which then underwent successive improvements.

The definitive cuboid form of the Sony ProFeel Pro (1986) had not previously been a feature of monitor casing design in Sony’s range. Formerly, the dimensions of the back edge of the monitor had not been identical to the front; instead, the casing at the rear of the screen had been visibly narrower. In contrast, and distinctively, however, the Sony ProFeel Pro articulates the quintessential cuboid form, with its operational components removed from view and suspended within the back frame. The cuboid shape of the monitor casing facilitates the stacking of monitors, while also functioning as a grip-bar, which assists in carrying. These practical attributes of the design substantially enhance the utility and versatility of the equipment for exhibition purposes.
