In areas close to the sea, in humid climates or during a long period when not used, it is important to protect outdoor furniture well, even when it is made of high-quality materials and finishes. For this reason, Casper coverings have been created: made of polyester fabric, they have a coated external covering that protects against water and humidity, with exceptional durability and breathability, whereas the interior minimises humidity and temperature changes, protecting furniture from mould, frost and heat. Once folded, they are not bulky and can be stored inside special internal pockets in some models, or in the extension trays of extendable tables.


In 1997 Kristalia created an in-house structure that deals with research and development, where new materials and manufacturing techniques are for product engineering are experimented. The work group, which is composed of professionals and technicians with solid and varied experience in the field of design and communication, can rely on a well-equipped prototype shop to give shape to new ideas.
