About Strings Stool

This stool draws inspiration from the sanshin, a traditional stringed instrument from Okinawa, Japan. Its warmth and string tension are expressed through natural wood, smooth curves, and tightly stretched cords. Cords across the seat allow everyday items to be clamped in place, creating moments of joy and comfort while evoking the presence and daily life of the user. Made using molded plywood, the stool achieves a smooth curve from legs to seat with layered wood ensuring strength, bringing warmth and gentle stimulation into daily living.

Yuna Yamashiro's Strings Stool emerges from a distinguished lineage of twentieth-century furniture design that recognized plywood's unique capacity to translate two-dimensional sheet material into three-dimensional sculptural form through steam-bending and lamination processes, engaging a material tradition established by pioneering designers who explored how industrial materials and techniques could serve both functional and aesthetic aspirations without hierarchy between these purposes. The work demonstrates exceptional technical facility in its continuous bent form, where structural engineering calculations regarding load distribution, cantilever physics, and material stress points integrate seamlessly with sculptural sensibility, the resulting object offering no visual evidence of compromise between pragmatic requirements and formal elegance. The compositional achievement resides particularly in how the negative space beneath the arch functions as actively as the positive material volume, creating a spatial dialogue that invites circumambulation and rewards viewing from multiple perspectives, each angle revealing new relationships between void and mass, between the organic flow of the wooden form and the geometric discipline of the tensioned cord seating surface. The chromatic restraint, limiting the palette to natural wood tones and deep indigo textile elements, establishes visual clarity that focuses attention on formal relationships and material character rather than surface decoration, demonstrating how limitation can generate aesthetic intensity. The decision to expose rather than conceal the laminated plywood edges transforms a structural necessity into an ornamental asset, the striations created by alternating wood layers providing rhythmic visual texture that traces the form's curvature and makes visible the material's journey through manufacturing process, thus embedding craft narrative within the finished object. The series of navy elastic cords stretched across the interior upper surface introduces a secondary formal system, their parallel horizontal alignment establishing geometric order that both contrasts with and complements the organic flowing substrate, this juxtaposition suggesting broader design discourse about orthogonal versus curvilinear formal languages, industrial versus craft production methods, and standardized versus unique fabrication approaches. The stool seems to meditate on furniture's essential task, the provision of stable elevated surface for human sitting, and explores how minimal means might accomplish this fundamental purpose while simultaneously achieving sculptural presence, material expression, and spatial elegance, questioning where necessity ends and artistry begins or whether such distinction holds meaning when design thinking operates at this level of integration. The work invites consideration of how everyday objects inhabit our spaces not merely as functional tools but as formal presences that shape spatial experience and aesthetic environment, how furniture operates simultaneously in utilitarian and cultural registers, and how thoughtful design elevates quotidian experience through attention to proportion, material, craft, and the poetic potential residing within necessary things.

Production Technology
The manufacturing process utilizes molded plywood, achieving gentle curves by applying pressure to bend the wood. The structure draws inspiration from the tension and stringing seen in Okinawan sanshin instruments, employing a multi-layered wood construction that ensures visual lightness while maintaining sufficient stability. Wood is carefully selected and utilized to convey the warmth and natural atmosphere of Okinawa.
Design Challenge
To bend wood using pressure, I created a mold. For clean bending, the wood must adhere tightly to the mold. Finding the right pressure application proved challenging one that ensures the wood stays firmly pressed against the mold while maintaining stability until the shape is fully set.
Project Duration
The project started in June 2025 in Okinawa and finished in September 2025 in Okinawa.
Operation Flow
Users can temporarily hold daily necessities and personal items by slipping them between the cords. Slipping favorite items into this stool can lift your spirits, while slipping in mementos can provide emotional comfort. The cords are also replaceable, allowing users to customize the color to match their preferences or room decor. The central opening in the seat is designed to fit the body comfortably, enhancing seating comfort, while the trapezoidal outward-spreading legs enable efficient stacking. This allows the stool to naturally blend into everyday life.
Research
Okinawa's traditional sensibilities spread worldwide, exploring of new design approaches that harmonize with contemporary living.As an island nation, Okinawa has developed its own distinct culture. The sanshin possesses a uniquely warm tone and form found only in Okinawa. In this stool, those elements are incorporated into the design through form, texture, and the experience of use. Such cross-cultural sensibilities will become a presence that brings stimulation to everyday life.
Inspiration
This stool draws inspiration from the Sanshin, Okinawa's traditional musical instrument. Its design incorporates the warm resonance produced by the sanshin's sound and the beauty of tension and harmony inherent in its stringed structure. Just as the Sanshin has been a constant companion in daily life in Okinawa, existing as a warm memory, This stool was designed to quietly receive moments of time and presence in everyday life, becoming an object that lingers in memory.
