While this chair looks like something you’d find in a Restoration Hardware showroom, its story is actually far more interesting. This is the work of Lucas Munoz, a Netherlands-based designer who turned to steel ventilation tubing to craft pieces of furniture. Part of the Objects From Interstitial Space collection, this chair is predominately composed of steel pipes and elbow connectors, and it’s finished with a copper seat that Munoz curved by hand. Then he attached everything using aluminum rivets, keeping the all metal appearance intact. The idea was to take something that normally functions behind the scenes (ventilation tubing) and bring it into the living room. While you can’t buy the Tubular chair, you can go to your local Home Depot and have a go at it.
