About Triad Sella
Triad est sella geometria triangulari designata ad stabilitatem praebendam spatioque optimando. E laminis metallicis curvatis ferruminatisque confecta, structuram durabilem et sedem leviter concavam ad commoditatem habet. Forma levis facilem motionem permittit, eam ad loca diversa idoneam reddens. Nulla compositione necessaria, Triad ad usum in domibus, tabernis et spatiis communibus destinata est. Conformatio geometrica efficientiam materiae efficit dum rationem practicam sedendi servat.

- Minimalist design, triangular geometry, metal furniture, modern interior, ergonomic, space-saving, durable, sustainable, CNC machining, laser cutting
- Production Technology
- Triad is manufactured using laser-cut metal sheets, CNC bending techniques, and TIG welding assembly. It is available in various finishes and colors to complement different interior styles.
- Design Challenge
- The main challenges of this project included optimizing structural strength while minimizing material usage and maintaining the visual and functional harmony of the triangular form. Precision in metal fabrication was also crucial, particularly in CNC bending and welding, to ensure consistent angles. Through multiple prototype iterations and structural testing, the final design achieved a refined, stable, and visually striking form.
- Research
- This project integrates user experience research with material engineering analysis. The goal was to develop a stool that balances stability, aesthetics, and sustainability. User interviews and ergonomic testing helped determine the optimal seat angle for comfort. The findings confirmed that the triangular geometry significantly enhances load-bearing capacity, while precision metal fabrication ensures long-term durability and efficient production feasibility.
- Inspiration
- Triad is crafted from bent and welded metal sheets, featuring clean lines and a focus on durability and eco-friendliness. Inspired by the geometric beauty of triangles, the design emphasizes stability and balance, while its minimalist form reflects the need for functional yet elegant solutions in modern living spaces.
- Project Duration
- The project began in October 2024 in Okinawa, was completed in December 2024.
- Operation Flow
- Triad is designed for direct use with no assembly required. Its triangular geometry ensures high stability, while its lightweight metal structure allows easy repositioning. The ergonomic seat provides comfortable seating, making it suitable for various settings, including homes, cafés, and public spaces.
