Seoul design studio Graft Object's Arch Bundle collection features a table and pair of stools that reference architectural vaulting (+ slideshow).

The studio referred to cross vaulting ? also known as double-barrel or groin vaulting ? to design the pieces, which are made from a wood-fibre and resin composite called Valchromat.

"The structural functionality of an intersected vault is not only useful for spanning architectural elements, but also to support people," said Graft Object which designed the collection as part of its ongoing Furniture as Architecture project.

Both tables and stools have square tops that rest on four legs, arranged to form a cross shape in plan. Each of the legs are made from a single panel with a segment cut out, forming a semi-circular opening when paired with the support opposite.
"Here, the apron and legs are combined into a single structural element, the vault," said Graft Object. "With this vault-structure we were able to keep the form comparatively slender at the bottom while retaining the capacity to support heavy loads."

"Structural strength and a sense of architectural aesthetics are achieved simultaneously in this design," the studio added.
