In the nineties the Euromobil Group has expanded the area of the living area. This choice was also helped by improvements in the technology of melamine that made it a more durable product and with better finishes. Before the development of the “Progetto Soluzione” has worked on the aesthetics of the products and on automatisms, elements that distinguish the product Zalf especially in the rooms for children. A very successful product, even now integrated in “Progetto Soluzione” , was the boiserie “Oh!ratio”, developed from the R&S Zalf with Roberto Gobbo since 1993. "Razio" refers to the rationality of modularity: in fact the boiserie gave way to a series of applications until then unexplored. Shelves and all the furniture - beds, desks and sliding systems- can be fixed on it. This is the first example of a structural wall from which all sliding track systems have been developed and they allowed creative design project especially in spaces for children. “Oh!ratio” is a modular system and it can be used in small parts, just like bedhead, or in large areas to organize a whole wall with fixed, hanging or placed on floor containers, beds and desks sliding on rails, settled in parallel or perpendicular to the boiserie.
