The way you sit is an indication of how much you care about your posture and your spine. And so chairs are not a mere decorative piece of furniture to compliments the rest in a set, but comfort and function also matter. So if you liked the Antoinette chair that doubled up as a room divider, then have a look at the Wallfa too. This is dual-purpose furniture that can be both a wall as well as a sofa. It is divided by a stretchy membrane separating the space in between to provide a comfortable sitting area that lets two people interact from both sides of the wall while seated. This 190cm tall, 26cm long, and 100cm wide chair can also be used as a double-sided vertical hammock to relax and socialize. Priced at $5,500, this black designer chair created by Jordi Canudas weighs 150kgs.
