Did you know the word “tetrad” refers to a shape made up of four contiguous squares? And that the inventor of the computer game Tetris came up with the name by combining this word with that of his favorite sport, tennis? Don’t feel bad if you didn’t – we only learned this piece of trivia when we were introduced to the Tetrad Flat Shelving System by Bravespace.

Tetrad is a modular storage and display solution consisting of five independent shelving units, each in a different tetrad configuration. Thanks to their interlocking geometry the units can be arranged in a variety of ways, and multiple sets can be combined to form larger shelving pieces.

Like many reconfigurable design pieces, Tetrad works well in small spaces because it allows you arranging the modules to get the most out of your available wall or floor space. And its economical 9-inch shelf depth provides just the right amount of surface for display and storage without encroaching on valuable real estate.

Units are assembled with metal backs in multicolor or white and wood veneer sides in maple or white. Made to order in the USA.
