On Belay is a lounge chair that reuses retired climbing ropes. Ropes that are no longer suitable for climbing keep their strength and flexibility, so they are woven into the seat and the backrest. The woven surface is soft and flexible, and it spreads weight evenly to give support without rigid parts. The frame is made of Kapur wood with lap and bridle joints reinforced by dual dowels at the corners. Traditional weaving methods are combined with climbing knots to bind the ropes to the frame. The chair measures 600 by 850 by 650 millimetres.

- Unique Properties
- On Belay ingeniously repurposes discarded climbing ropes as integral structural and tactile elements of a lounge chair. Though no longer fit for safety-critical use after extended wear or falls, these ropes retain strength and flexibility ideal for furniture applications. Woven meticulously into the seat and backrest, the design redefines lifesaving equipment into a durable, sustainable, and comfortable seating experience that bridges heritage craft with modern ecological responsibility.

- Production Technology
- The seating structure combines traditional weaving techniques learned in Thailand with climbing rope knotting methods to bind reclaimed ropes securely onto a Kapur wood frame. The chair’s frame uses time-honored joinery methods including lap and bridle joints reinforced with dual dowels at frame corners to ensure strength and durability.
- Design Challenge
- The hardest part of this project was that it was our first, so many aspects were unfamiliar, especially weaving and knotting techniques. These skills required extensive practice and patience to master. Additionally, limited information and guidance made the learning curve steep. Overcoming these challenges deepened my understanding of material manipulation and craftsmanship, which was crucial for realizing the design successfully.
- Project Duration
- This Project started in August 2025 in Singapore NAFA and finished in NAFA's workshop.
- Operation Flow
- The woven climbing rope seat provides a soft, flexible surface that naturally conforms to the human body, evenly distributing weight to deliver ergonomic support without rigid components. Its minimalist yet stable construction fosters a sense of security and calm, evoking the trust foundational to climbing safety. This tactile interaction invites relaxation and mindfulness, transforming the chair into a restorative haven for body and mind.
- Research
- I focused on upcycled materials and chose climbing ropes for this project. I researched various weaving techniques and climbing knotting methods, alongside exploring line art for visual inspiration. During mock-up stages, I drilled multiple holes to find optimal positions and consulted with my mentor to determine the best structure and joinery for the chair frame. I tested different diameters of climbing ropes and ultimately selected 5mm support rope for its balance of aesthetics and comfort. I am very satisfied with the final product. This design taught me that upcycling can be both practical and visually appealing.
- Inspiration
- Inspired by the themes of safety, trust, and connection inherent in rock climbing culture, On Belay transforms retired climbing ropes symbols of protection and resilience into core materials for furniture. These ropes embody stories of endurance and rebirth, and through creative upcycling, the design offers a poetic metaphor for rest and renewal, highlighting sustainable innovation intertwined with emotional narratives.
