The Button side table is a creation of Norway born Switzerland based designer Fredrik Wærnes. He developed this elegant and minimal piece with the purpose to provide versatility in the living space. The tabletop can be removed and used as a serving tray. The grooves in the middle of the wooden base keep the tray tightly and securely in place.
I like the opening in the center. Aside from being a visual feature, making the tabletop resemble a button (hence the name), it creates handle and makes the piece easier to move.
