There's not much detail about this extraordinary sofa-design, but the video hints at an intriguing and excellent design. The sofa appears to be made out of hundreds of thin, flat chair-shaped silhouettes, joined together by some kind of membrane in an accordion that can collapse down into a dictionary-think chunk or be spread out for feet on end, as a divan, chair or sofa.
Update: Norman sez, "Just got off the phone with Molo Design. They do not, as your correspondent, Vanessa, suggests, make the accordion chair." He sends this link to this company, who appear to be the manufacturers.
