Liao bent strips of wood in a set of 12 slightly different moulds using precise digital moulding techniques to form the seat of the chair. The moulded wood mimics the curvature of a traditional coffin.
In order for the coffin to be cremated, the chair is made solely from wood, without any metal components.
Coffin chair can be used as a regular piece of furniture whilst the user is alive. After they die, family members can transform the seat into a casing for the dead body before cremation.
The base of the chair slides open to the length of a human body, which causes the bent wooden elements to unfurl like a spring, leaving a series of small openings in a wooden sheath that surrounds the body.
"The spring structure not only has the function of extension, but also has the symbolic meaning of a long life," explained Liao.
According to Liao, the Chinese government is aiming to implement a comprehensive policy of cremation by forbidding the practice of burial.
As part of the Green Funeral movement implemented by the government in 2018, .
The designer says that many people have had their coffins forcibly removed from their homes. Coffin chair respects the ritual of preparing your own coffin, something that Liao feels is important to the elder generation.
"We are creating a more efficient and modern world, many rituals have disappeared, but that doesn't mean we feel happier," said Liao.
"The ritual should not be simply copied or abolished, we should keep our traditional values while catering to social development."
Currently many Chinese people in their 60s organise their own coffins long before their death, in a bid to wish for a long life. They often live with their coffin at home, so the Coffin chair would be an extension of this tradition.
Heavy investment in funerals and coffins is believed to be a way of showing filial piety towards ones ancestors in China.
However, as , the Chinese government is now encouraging sea burials, tree burials – where the cremated body is buried under a tree, as well as vertical burials and smaller tombs.
BestDealStore2Buy recently rounded up five designs for a sustainable death.
These include a coffin laced with fungal spores that help biodegrade the body, and an egg-shaped pod that in which the deceased is placed in a foetal position before being buried and a tree planted on top.
Meanwhile, euthanasia advocate Philip Nitschke suggests the more radical solution of a 3D-printed machine called Sarco that allows users to administer their own death at the touch of a button.
