Embodiments generally relate to hinge mechanisms. Many of the hinge mechanism embodiments may be used in foldable furniture. The foldable furniture may be a foldable seat or table. The hinge mechanism may include a central cylinder with a body defining a hinge axis. The central cylinder may have rotate channel(s) transverse to the hinge axis and locking channels extending axially from the rotate channel(s). Collar(s) may couple with the central cylinder and may include pin(s) that protrude inwardly into the rotate channel(s) and locking channel(s) of the central cylinder. In some embodiments, an intermediate cylinder may be disposed between the central cylinder and the collar(s). The intermediate cylinder may have slots corresponding to the rotate channel(s) of the central cylinder. When pin(s) and locking channel(s) are aligned, the central lock cylinder may move axially to lock the collars in a desired angular position (e.g., a deployed or folded configuration).
