Rebuilding a Classic with Grid Beam

What happens when open-source modular design meets a design icon?

With just a few Grid Beam parts and a splash of paint, we recreated Gerrit Rietveld’s legendary Red and Blue Chair—a cornerstone of the De Stijl movement and one of the most recognizable pieces of modern furniture design.

Thanks to Grid Beam’s standardized hole pattern and easy-to-bolt connections, adapting this century-old masterpiece was fast, fun, and fully reversible. No glue, no guesswork—just pure geometric play.

Whether you're a student, a maker, or a modernist at heart, Grid Beam lets you bring iconic ideas to life—and reimagine them your way.

Modular. Adaptable. Iconic. Grid Beam it.
