I think the success of the video game Tetris is its simplicity, which makes this game very addictive.
Many people become obsessed with the idea of putting lines to go with different figures to such an extent that they can carry it to real life. A specific case is the designer who created Silvério Diego Furniture Tetris, which basically takes the characteristic of the legendary game blocks and transforms them into mubles for office or home.

The fact is that your idea is not innovative, but he adds his own touch, making 100% minimalistic, perfect for a bachelor apartment or a couple who are not interested in expensive furniture. Although they are considered furniture designer and all that, if this furniture concept was developed to reach may not be the cheapest, but if you are given the job with some material like wood and have time available, it can manufacture their own furniture Tetris.
