The Opus is a symbolic product with uniquely designed legs. Tables are always designed to fit chairs for ease of use with various designs even with distinct characteristics. We also take the relationship between a table and chairs into consideration so that many chairs can be set from various angles. The distinct dogleg shape of the legs is cut from a single tree.

Using a joining method called agodashi, the parts that join at the center are given a sense of oneness and strength. The legs are placed on the inside at an angle, not for design purposes but to prevent the knees from hitting when people sit anywhere at the table. Also, most tables have a sideboard in the back to connect the tabletop to legs and to prevent the tabletop from warping.

In contrast, the Opus has more space under the tabletop because the legs and tabletop are secured using special joint hardware instead of a sideboard. The legs are connected at the center and an elliptical crosspiece is used to connect the middle of the table to both legs. These features distribute the added weight throughout so that the table can bear a force applied from above. Because we thought connecting elliptical legs and crosspieces naturally would be important, the challenge was to determine the design and the thickness of the wood to retain strength.

The Opus comes in three types: rectangle, square, and round types. The round table has parts to connect the four legs in the middle, which are made from a single tree. The curved wooden connecting parts give increased strength to these legs.
