Fibre-glass reinforced polypropylene


Klia is a stackable plastic chair, with and without armrests, with a lightweight design and a robust core. The simplicity of a monobloc chair in fibre-glass reinforced polypropylene conceals complex engineering and substantial investments in gas-assisted injection-moulds for mass production. Thanks to the well-established partnership with Kastel, the project was developed together, from the initial concept to providing support during the production phase.
