italian studio spalvieri + del ciotto‘s ‘sacchetto’, on display at the salone satellite during milan design week 2011, is an armchair created from a study they are conducting on the use of Tyvek® for interior design solutions. Tyvek® is a non-woven high-density polyethylene (HDPE) which is water-proof and extremely resistant to UV light, typically used in the construction of buildings. its appearance is quite similar to paper, atoxic, chemically inert and does not contain a binder. the studio devised an innovative method in order to join pieces of material without using glue or sewing where sheets are soldered through an ultrasonic technique, and rendering the joints water-proof.
‘in this way we could create an unbelievably resistant armchair, ideal for indoors or outdoors, which maintains the delicate and frail look of paper. you are able to sit in the yard on an armchair seemingly made of paper, but durable enough to be cleaned with a wet sponge.’ -spalvieri + del ciotto
