Production Technology

The chair production is guided by sustainability and industrial efficiency. It uses responsibly sourced reforested Jequitiba wood and components designed to reduce waste throughout manufacturing. The seat incorporates curves that adapt to human anatomy combined with high performance foam for comfort and support. Industrial machining ensures precision and repeatability while controlled manual finishing preserves material integrity and durability.

Design Challenge

The main challenge was balancing ergonomics and form. Developing a continuous curved backrest capable of adapting to different bodies required extensive research, testing, and fine adjustments. Manufacturing the wooden structure demanded high technical precision to achieve organic forms and smooth transitions without compromising structural strength. Integrating wood and leather also required careful detailing to ensure durability, comfort, and consistent aesthetic quality in potential scaled production.

Research

This design project was developed through research into sustainable materials applied to contemporary furniture, combined with an understanding of function as an adaptive element responsive to different bodies and contexts. The design process integrated hand sketching, 3D modeling, and full-scale prototyping to refine form, structure, and ergonomics, particularly the backrest curvature. The combination of wood and leather references Brazilian modern furniture, positioning craftsmanship as the conceptual core of the object.

Inspiration

The Soli chair inspire by a synthesis of form, identity, and materiality. Its design is structured as a continuous gesture, in which seat and backrest are unified through a single curve. Each curvature is carefully dimensioned to accommodate diverse body types, reflecting the plurality of Brazilian culture. Inspired by traditional wooden furniture and natural elements such as branches and animal horns, the combination of wood and leather emphasizes material honesty, lightness, stability, and tactile comfort, enhancing the users sensorial experience.

Project Duration

The Soli chair was developed through close collaboration between designer and manufacturer with the objective of creating a chair that intuitively adapts to the human body. Completed in 2025 the project followed a rigorous development process with multiple prototypes ergonomic adjustments and formal refinements. The result is a contemporary chair that balances comfort aesthetic identity and production feasibility reflecting research collaboration and care in its creation.

Operation Flow

The chair works as a single, continuous gesture. The seat supports the body, while the curved backrest approaches like an embrace, intuitively guiding posture. There are no adjustments or mechanisms: comfort comes directly from the form itself, which naturally adapts to different body types. The wooden structure sustains this movement with lightness and stability, transforming the act of sitting into a natural, welcoming, and efficient everyday experience.
