Chair No. One
$4,200.00
An iconic piece like none other, the Oberhauser Chair No. One draws its inspiration from forms found in nature, while embracing the capabilities of the groundbreaking technology which gives it form.
The first piece in the Oberhauser Collection. Concrete, shaped by code and finished by hand.
The Chair No. One is a study in bionic form — design language drawn from the geometries of plants, coral, and weathered stone, reinterpreted through algorithmic methods. It is printed as a single continuous piece: no joinery, no assembly, no internal seams. The lattice is both seat and structure. Light passes through it. So does air. What remains is a quiet object — dense at the hand, weightless to the eye.
Studio Oberhauser
Designed by Martin Oberhauser, founder of Studio Oberhauser. The Chair No. One is the first in a series of chairs inspired by forms found in nature — patterns of growth, structure, and weather. Each piece is approached as a study in tension: between mass and void, permanence and movement, the digital tool and the human hand. A Red Dot Award recipient.
Selective Paste Intrusion
The Chair No. One is printed in Selective Paste Intrusion (SPI) — the highest-resolution concrete 3D printing process available today. Where extrusion-based concrete printers lay continuous beads, SPI selectively binds a dry aggregate matrix layer by layer, producing geometries no other concrete process can reach.
The print method leaves its own signature. Fine ring-like patterns emerge across each surface, much like growth rings in wood — a record of the printing process visible in the finished piece. No two chairs are identical.
Each chair is hand-finished in our Caledonia, Michigan workshop — three generations into the Kerkstra family’s work with concrete.
