ABSTRACT:
A foldable furniture device includes a looped frame, two first leg sections, and two second leg sections connected pivotally and respectively to the first leg sections so as to move between folded and unfolded states. Two sleeve units are sleeved slidably and respectively on the first leg sections, and each includes a positioning hole. Each sleeve unit slides toward and away from top ends of the first leg sections in the unfolded and folded states, respectively. Two locking units are inserted respectively into the first leg sections, and each includes a resilient positioning member that extends through a through hole in the corresponding first leg section to engage the positioning hole when the first and second leg sections are pivoted to the unfolded state so as to lock each sleeve unit against sliding movement.
