IMM Cologne is not really on my list of the top furniture fairs, but I had a great time in Cologne.
The best part of the fair was the [D3] design competition. The winner of the competition, Jolan van der Wiel, made a stool formed by magnetic fields. The whole aspect of using gravity to design is genius.
Another designer worth mentioning is Jakob Schenks. He came up with a leg system that can be applied to a variety of tabletops.
Besides the IMM fair, Cologne had a lot more to offer. They have a muji store!
Just kidding, the Kolomba museum is definitely worth visiting and the dome with this amazing contemporary stained glass by Gerhard Richter.
