Think of a chair—an everyday object that often goes unnoticed due to its constant use. It’s a lightweight piece of household furniture where comfort and aesthetics go hand in hand. After all, what’s a chair for, if not for sitting down to eat, converse, wait, rest, and savor life’s moments? We’ve sought to define the essence of our ideal chair, one that embodies the characteristics of a joyful and inviting object, naturally leading to evenings spent in the company of friends, family gatherings at home or in the garden, and moments when chairs are rearranged to accommodate new arrivals. It’s a chair that can be effortlessly stacked at the end of the day or left outdoors overnight, unaffected by the rain. An object with no boundaries, except for its practicality, comfort, and user-friendliness.

The Joi collection pays homage to one of the greatest masters of the 20th century, Hans J. Wegner, following the same principles of beauty, simplicity, and ergonomics. It adheres to the distinct line of proudly modern Nordic design, where real design is rooted in life, rather than following fleeting fashion trends. Joi combines all of these elements with advanced construction techniques that enable accessible and versatile production in various versions. Its standout feature is the joint that allows for the creation of three different chair models, each with distinct personalities, uses, and purposes.

The selection of colors aligns with the idea of a resolute yet adaptable object. With four different colors for the structure and five fabric options for the removable seat cover, the Joi collection offers a wide array of combinations to match the ambiance of its intended setting.

Simone Viola

Simone Viola was born in Mendrisio, Switzerland in 1985.

After rigorous training in industrial design in Milan and through his collaboration during various architectural and design studies, he began to gain experience in Switzerland and abroad. In 2011, he founded the Simone Viola Design Studio, focusing on industrial projects for furniture and accessories. His philosophy leans toward research on the materials and technical aspects related to the development of the project, conceptually guided by historical and artistic references. This approach produces the most natural connection to contemporary design, where the object is not the expression of a trend, but a long-lasting fusion of form and the intended use. Soft, natural elegant shapes and elevated attention to details characterizes his work and continuous optimization of the development phase allows the realization of high quality and generously accommodating products.

TOOU Design


TOOU is the realization of a utopia: ergonomic, accessible and versatile designs applied to everyday objects. Conceived for both interior and exterior furnishing, for singles and communities alike, with a cross-fit aesthetic that adjusts to every living style, Toou objects are designed and built for each one of us. A meeting point between the European and Asian cultures, in 2015 TOOU started creating design objects taking account of people above all. TOOU was born out of the blend of European taste for design, in its Italian, Swiss and Northern European interpretations. Italy is the creative heart of TOOU, where designs take shape and where the upholsteries are tailored following accurate research on materials and colour combinations. Our moulds are then developed and mass-produced making the best use of consolidated experience in the manufacturing of plastic products for renowned furniture industry partners. The production of TOOU moulds is entrusted to a company with over 30 years of experience in the sector. The quality of moulds and finishes is the same as applied to the production of components for the automotive industry, which requires very high-quality standards. Our primary goal is to make each object as desirable, affordable and customizable as possible, making use of a wide range of materials, shapes and colours, in order to turn a mass-produced product into a highly personal one. Our products are the material realization of strong, detailed ideas. Toou aims to create long-lasting objects, both in construction and in aesthetics silhouettes and volumes that will become trustworthy companions of your own domestic landscape.
