The collection of chairs features backrests, legs and arms created using sausage-shaped inflated modelling balloons. Stools have seats made from a single balloon coiled around itself, and rest on gently curving legs.
"I tried to turn a simple making process based on my personal childhood memories into an industrial fabrication furniture-making process," Yang told Dezeen.
Although the furniture looks fragile, Yang used eight layers of epoxy resin to create a rigid outer surface.
Each piece needs around half a day to be coated in a single resin layer, with successive layers gradually added on top of it. As the resin sets it creates a glossy and solid surface, that's able to support weight. The process takes a week to complete a single stool.
Dutch designer Marcel Wanders previously coated inflated balloons in strips of lightweight carbon fibre and epoxy resin, to create a chair.
"I was fascinated by a form that is changed into a transparent and clear surface like glass when I set epoxy resin on balloons," said Yang.
"After a time balloons' surfaces lose gloss and become deflated," he added. "However, when I repeatedly coat epoxy resin thickly, I can make a solid form. It turns into attractive furniture, like glass."
Yang had first attempted to use balloons to make lighting, but after experimenting for a few months decided to pursue furniture instead.
"Comfort is not my prior intention when I create works," he said. "They are not soft or comfortable, but they have stability when people sit on them. It feels like plastic stools."
The shapes of party balloons influenced Dutch designer Marten Baas's collection of hand-blown glass pendant lamps, while Swedish designer Jomi Evers Solheim borrowed the forms of water-filled balloons to design a range of ceramics.
