A stylish and comfortable chair available with a high or low back and the option to choose with or without armrests. The design is characterised by a flowing and clear line, defined soft contours, a seat shell with an iconic shape and a well-coordinated back curve that gives the furniture a clear and modern character.

Through OPUS, Johanson's range is further broadened. A model that is slightly more compact than Milo and with a narrower backrest, OPUS is a perfect model around the meeting table. Choose between four different bases and enable flexible furnishing.

The upholstery gives a soft feeling with the clear indentations that become

a nice detail. Johanson's flexible production opens a wide range of textile options. Create personal environments with a model that is both comfortable and appealing.
