Foldable support for foldable furniture

Abstract

A foldable furniture includes a supporting top, a leg pivotally connecting with the supporting top, and a foldable support including a first retention arm pivotally connecting with the supporting top, a second retention arm pivotally connecting between the leg and the first retention arm, and a sliding locker. The second retention arm is pivotally folded to align with the first retention arm at a position that a locking slot of the second retention arm is aligned with an engaging slot of the first retention arm so as to retain the leg at an opened position. The sliding locker is substantially engaging with the locking slot and the engagement slot to securely lock up the first retention arm with the second retention arm so as to lock up the leg at the opened position.
