Loved by the designer, who defines it as "a breath of indispensable relaxation", Soriana was awarded the Compasso d'Oro in 1970: the pair of designers and the company had managed to create a piece of furniture with abundant and enveloping curves, taking advantage of of the padding technique with polyurethane foam, a novelty of the time destined to revolutionize the manufacture of sofas and armchairs. The padding made it possible to create a soft piece of furniture, to cover it and fix it through a large metal vice so as to form soft folds around the whole person.

In the new version, Soriana is available as an armchair, chaise-longue, two or three-seater sofa and pouf. This is what we can define as a design culture operation, the result of a conscious evolution, thanks to the work done by Cassina LAB, the collaboration between the Cassina Research and Development Center and Poli.design of the Milan Polytechnic. The original polyurethane structure has been completely replaced by a series of bags filled with BioFoam® microspheres, the first patented foam with an organic base composed of biopolymers obtained from natural resources. This material is durable, suitable for long-term use and is biodegradable, so it can be industrially composted.

The comfort of the seat is further increased thanks to a blown fiber padding made from 100% recycled Pet from Plastic Bank®: thanks to the involvement of local communities, the plastic is collected before it reaches the sea, favoring a conscious economy and circular. The same material is also used for the padding of the lining that wraps the structure like a soft quilt.
