Bouba/Kiki effect — THE CONCEPT
A rocking horse chair that lets you rediscover
the shape-memory hidden in your subconscious.
This rocking horse chair places the Bouba-Kiki Effect — the innate connection between shape and sound — at the heart of its design. It is a work that fuses sight, touch, and sensibility. The contrast between flowing curves and sharp angles awakens a difference in feeling that rises from somewhere beneath conscious thought.
More than a chair, it is a wellness tool crafted to help you rediscover your own senses through form and texture.
Regardless of language, gender, or age, most people associate round shapes with "Bouba" and angular shapes with "Kiki" — this is the Bouba-Kiki Effect. BBKK invites you to experience that universal instinct with your whole body.
TYPE 01
BB / The rounded rocking horse chair
Flowing curves envelop your entire body. Sight, touch, and emotion converge — as if the boundary between mind and body gently dissolves. An encounter with the memory of softness that sleeps within you.
TYPE 02
KK / The angular rocking horse chair
Sharp edges call forth a distinctive tension and exhilaration. Unsettling? Compelling? Whichever you feel first reveals the hidden tendencies of your own perception.
MATERIALS & CRAFT
Made from cedar and cypress plywood grown in the mountains of Yokoze, Chichibu District, Saitama. The design embraces local forest resources, weaving the cycle of timber into its very form.
CNC routers carve complex curves and angular silhouettes with exacting precision. Layered construction yields both a distinctive three-dimensionality and structural strength.
We actively reclaim offcuts and waste from forestry operations. By breathing new life and value into wood that would otherwise be discarded, we aim to give back to the local community and the environment.
"By making the most of timber that would otherwise go to waste, we want to contribute to the community around us.
We believe a rocking horse that carries the story of its materials can enrich the senses of those who ride it."
