010 Lounge Chair is a minimalist chair created by Athens-based studio OFAA. The only structural principle used here is the fold, and every aspect of the chair’s function comes from that single action, repeated across a few aluminum sheets. Bending a flat sheet along a line transforms it from a flexible panel into a rigid beam by adding depth along a second axis. This is why the chair requires no frame, brackets, or hidden fasteners doing structural work beneath the surface.

At five millimeters thick, this aluminum is unusually heavy for folded furniture. Most similar pieces use metal between one and three millimeters—thin enough to be shaped with moderate press force and tolerant of tighter bend radii. At five millimeters, however, the demands on the press brake increase significantly, the minimum bend radius grows, and the outer edge of each fold is stretched near the point where the alloy risks cracking. This constraint drives the design. Every bend must be tailored to what the material can withstand, not what the initial sketch might prefer, and the resulting radii appear as gentle, uniform curves rather than sharp angles.

Aluminum has about one-third the stiffness of steel, which is typically a drawback for unsupported spans. But in a lounge chair, that becomes a source of comfort. A folded panel supported at its edges bends slightly under weight and then springs back, giving the seat a yielding quality without any padding, foam, or suspension system. With overall dimensions of 50 x 60 x 80 centimeters, the chair is compact for a lounge piece, and its low seat paired with a tall back suggests the user is meant to recline into that flex rather than sit upright.
