A supportive spinal brace easily configurable to support disabled or injured and various chosen postures. The spinal brace comprises a plurality of rotatably interlocking components (101). The rotatably interlocking components are able to interlock together line at various user configurable rotational offsets to form a user configurable supportive undulation along the length of the brace. In an embodiment, the rotatably interlocking components define portions which interlock together at medial side (104, 105) thereof and at lateral sides (106) thereof with laterally adjacent plates (108), thereby supporting each interlocking portion at both medial and lateral sides thereof for enhanced structural integrity of the brace.
