Coccyx is a compact structure derived from the anatomical memory of upright posture. Inspired by the fused vertebrae at the base of the spine, the chair reimagines the coccygeal sequence not as obsolete, but as origin — the convergence point of balance, tension, and support.

Through computational thickening, postural analysis, and mineral printing, the piece translates vestigial compression into spatial presence. Coccyx is not a seat—it’s a tectonic suture, where motion concludes and form holds.
