Boss Design Sia Eco Friendly Office Chair

Maximum Comfort & Support

Ergonomic Comfort

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.
