Upgrade is designed by Giorgio Soressi for italian manufacturer Calligaris. The broad angularity of the sofa is supplemented by a soft padding. The backrest can be adjusted to a number of different positions, using a exposed snap mechanism in chrome-plated metal. Under one of the amrrests is an integrated bookshelf in white, lacquered wood, for everything the relaxer, reader or couchpotato might need. Upgrade is the sofa you never have to leave.
