The Holding-Breath Chair, designed by Chinese designers Ray Jiao and Yi Wang, integrates vacuum compression systems that mould the seats to the shape of each sitter.
The seat of each chair in the Holding-Breath collection is a detachable PVC bag, filled with foam particles and fitted with a valve that allows air in and out.
To mould the chair, the sitter connects a hand pump to the inflated bag and uses it to exhaust some of the air. This process also allows the foam particles to bind themselves around the sitter's back and hips, holding the seat in place.
Storage pockets are included behind the backrest for hiding the pump and storing other items.
Air can be simply pumped back into the valves to rebuild the chair for a new sitter.
The collection includes a rocking chair, a bar stool and a sofa. Each has a wooden frame that is attached to the bag with nylon strings and plastic plugs.
