The outdoor ‘Concave’ family is hammered from a single steel tube. In search for a way to interconnect a single material with itself, Christian Heikoop discovered that; by gradually hammering metal tubes flat toward the end, they can be inserted in another tubes void. Creating a new construction language solely using a standard industrial steel tube. Next to the fact that the individual metal rods are shaped according the way they should connect with each-other, they are hammered to flow along with the body. The armrests are shaped to the palm of the hand and the back flows with the curve of the back. The final chairs and benches appear very light, almost disappearing in certain places due to it’s thinness – merging within its surrounding.
