The 3D-printed ECHO Chair developed by ZHA for Nagami explores an echo as a geometric condition rather than an acoustic phenomenon. Instead of repetition, an echo is understood as a transformation—a single geometric logic unfolding into multiple structural, spatial and material expressions.
3D-printing with recycled plastics, Nagami has created a new ecosystem for architecture and design—recovering what others have left behind, transforming waste into design, ready for a new life. From residue, form is born.
Generated from two continuous surfaces emerging from a shared structural edge, one surface of the ECHO Chair becomes an echo of the other; evolving from the same underlying geometry while assuming a different role. From this line of contact, one surface forms the seat and base, while the other develops into the backrest and supporting structure. Conceived as a single continuous system, the chair dissolves the distinction between structure, surface and ergonomics.
Developed through an iterative research process at ZHA Lab, the ECHO Chair combines computational design with large-scale additive manufacturing. Produced through continuous-extrusion 3D printing, the chair is fabricated as a single uninterrupted process, where geometry, structure and fabrication emerge simultaneously rather than through the assembly of separate parts.
The ECHO Chair extends the concept of resonance beyond geometry. The continuity embedded within the chair’s form defines the relationship between object and user.
The chair’s material palette explores different expressions of the same geometry, moving from translucent and reflective finishes to warm mineral tones and deep opaque black. Together, the collection is a continuous spectrum informed by the subtle tonal transitions found in natural landscapes, reinforcing the design’s themes of continuity, transformation and resonance.
Measuring 543×634×699 mm, the ECHO Chair combines ergonomic precision with a sculptural presence.
The ECHO Chair collection by ZHA for Nagami is currently showcased within the free-to-visit LONDON CREATES exhibition curated by ZHA and Archisource at The Truman Brewery, London until 26 July 2026 (11am–7pm).
