It was a pleasure to create this wonderful piece of furniture, as well as a wonderful feeling to enjoy the fact that it will meet the expectations of its users. The ILLUSION program is a complete proposal of furniture that meets all the requirements of modular systems. Its mobility and wide configuration of modules allow the furniture to be adapted not only to interiors with standard dimensions but also to spaces with artistic visions. At “first glance,” the program, with its small number of modules in the offer, provides an inexhaustible number of arrangements with minimal effort. The only limitation is one’s own sensitivity to “tuning” the shape of the furniture to the interior. An ergonomic seat combined with a well-shaped backrest is an excellent response to fatigue that appears at the end of a busy day, and the “longchair” module is the essence of what is known as the reduction of exhaustion after hard work. The seating surface of ILLUSION is not only comfortable in its softness but also practical when rest is needed. The entire program is built on specially selected seat springs as well as hardwood and high-resilience polyurethane foams, tested specifically for this type of (modular) furniture.
