The New Boss Design Sia Eco Friendly Office chair
Sia is the latest task chair from Boss Design and is heavily focused not on on ergonomic comfort but also the environment.
Product Details
100mm lumbar height adjustment
65mm seat depth adjustment
120mm seat height adjustment
Intuitive weight-balance mechanism with additional tension adjustment
Black Nylon five-star base with black castors as standard
Height adjustable arms
As standard, the Sia lumbar pad will be colour matched to the frame colour chosen (Black, Copper Brown, Reed Green and Oyster White).
During the Sia chairs design process sustainability was key.
With the Sia Chair Boss managed to drive the plastic used in the structural parts of the chair down to just 20%. The remaining 80% is recycled plastic.
Sia Eco friendly chair uses fewer components than most task chairs and is assembled without the use of glue.
This makes replacing damaged parts more feasible extending Sia’s longevity while also making it easier to separate and reuse or recycle components at the end of its life cycle.

Our design team worked closely with leading ergonomist Levent Çaglar at FIRA while developing Sia, resulting in a task chair providing optimum comfort and support.
With the right amount of flex and twist in the back section, Sia moulds to the human form, providing lumbar support without restricting movement.
Its generous high back, a lumbar pad that is adjustable across a 100mm range, and multi-adjustable armrests make Sia customisable to a wide variety of body shapes and sizes.
This is a chair built for maximum comfort, concentration and focus, facilitating wellbeing and productivity in the workplace.
