Abstract
A folding furniture piece including: a spring mechanism including a flange; an articulated vertebral column including multiple vertebral members arranged and operatively connected via one or more connecting members to form a flexible unit including the vertebral column and an object base; a locking mechanism located on the object base; the spring mechanism exhibiting properties such that the folding furniture piece assumes an unfolded state where both the vertebral column and spring mechanism are substantially straight to provide a closed sitting surface and, in response to a bending force, assumes a folded state where both the vertebral column and spring mechanism are curved to expose the sitting surface on which an object can rest, and where, in response to the bending force, the spring mechanism travels along the object base such that the locking mechanism operatively interlocks with the flange and the folding furniture piece remains in the folded state.
