Bulgarian designer and National Academy of Fine Arts graduate Konstantin Achkov‘s ‘Stack Furniture’ slots together like pieces of a puzzle. The innovative furniture design doesn’t need nails, glue, or bolts, relying only on intricate interlocking shapes and pins of beech plywood. The chairs, stools, and tables come flat-packed and are designed to allow anyone to easily assemble, dismantle, repair and transport them. The furniture was presented at Sofia Design Week earlier this month and will be produced by new manufacturer Tenon. Click through to see pictures of the Stack Furniture:
