A control structure of supporting foot for collapsible furniture comprises a base having a rotation shaft fixed on a supporting foot. A concave hole is formed in the base and an extension shaft of the rotation shaft is combined with a spring and a sleeve. When the supporting foot is rotated to a predetermined position where the sleeve aims exactly at the concave hole of the base, the sleeve is pushed into the hole by the spring to fix and unfold the supporting foot. On the contrary, when the sleeve is pulled out of the hole, the supporting foot is free flow for getting folded and closed together with the furniture body by relative rotation.
