“The originality of the armchair is not only its ability to completely change the atmosphere of a lobby or lounge by simple means in the form of a seat and three different backs. But it also offers the possibility to easily change the upholstery and renew the armchair. As people work more in public places, the need for easy upgrades increases”, says Daniel Debiasi. Shift is an exceptionally flexible armchair, through the different heights of the backs, allows everyone to both focus completely on their work and to rest completely. The backrests can be replaced and renewed as needed, according to Offecct Lifecircle. It also offers architects tools to create sustainable solutions. The seat is the same for all three designs.
