For the design of the Kai collection, Treku has worked with the prestigious French designer Jean Louis Iratzoki. Together they have created a system characterized by a harmonious blend of solid wood and different materials such as colored lacquer, felt, and even marble. In other words, they combine fine, high-quality materials with a range of fresher, more modern elements. The personality of each piece will depend on the elements used to create it, with a wide range of styles available, from the more open to the more functional and from the more colorful to the more sober and restrained.
