Dezeen Showroom: Danish furniture brand Mater has released a new stackable shell chair named Eternity, which is made from a combination of upcycled plastic and coffee waste.

The chair was created by design studio Space Copenhagen to have a rounded seat and back, which is intended to make it comfortable and sculptural.

"Easily integrated into various kinds of spaces and interiors, the chair's design focuses on comfort and functionality combined with industrial and sculptural features," said Mater.

According to the brand, the seat of the Eternity chair is made from 70 per cent industrial plastic waste and 30 per cent waste from coffee shells.

The waste is combined into a composite material and used to create the moulded seat.

"This technique allows efficient upcycling of industrial waste while simultaneously reducing carbon emissions, instead of the waste being burned," said the brand.

Eternity has steel legs and a dark brown seat with a textured surface, which varies slightly between products due to being made from recycled materials.

The chair was designed to be easily disassembled, allowing each element to be upcycled in the future.
