Bulgarian product designer Petar Zaharinov has introduced a new collection, Coordinate, under his Prakrik label. Like his other lines of “puzzle furniture,” the pieces are inspired by interlocking, wooden burr puzzles, and meant to stimulate some intelligence from the user. The components, which fit together without the use of tools, are made from beech plywood produced locally and finished with natural plant oil.

The names of the pieces are formal representations of the structure. For example, with the VST (a stool or side table), the first digit “V” is the Roman numeral 5 and “S” and “T” stand for stool and bench respectively, which are the two ways the piece can function. Can you figure out what VIIB stands for? A bench made from seven components, of course!
