Breaking up is easier to do given the Splinter Chair by Matthew Kroeker for Jane Hamley Wells. It's designed to break. The chair is made of uneven slats in a right and left version. The two can fit together to form a bench, and likewise break apart to form two separate chairs.

On the materials for the chair (teak with stainless steel legs), Matthew says: The bench is teak because it wears well outdoors, but I don’t want it to be seen only as a piece of garden furniture. The wood is responsibly harvested, either plantation-grown or from a managed forest.

I didn’t want anything to distract from the seat and back, so the stainless-steel legs are quite sparing. It’s the next best thing to having the bench just hover above the ground. Via Metropolis.
