Two supports fixed perpendicularly on the wall make it possible to have very deep shelves. This is the shelving Cristalina. Consequently, they can hold not only books but music systems, televisions, computers, etc. and can even become a small workspace. The Hypóstila shelving was designed in 1979 by Lluís Clotet and Oscar Tusquets, with advice from the engineer Jesús Jiménez, in such a way that it can take heavy loads using minimal sections and achieve an infinity of sizes and arrangements. In 1995, a new shelving model was manufactured, this time based on tubes along the lines of an idea of Enric Miralles. Shortly afterwards, Cristalina, which makes the most of the structural qualities of Hypóstila and offers other features, came into being. The range is now extended through the addition of Esbelta, Suma and Exenta, which further exploit the innumerable possibilities of the original design.
