A security bench for use as a seat and as a defensive barricade against vehicles and explosive force comprises a support base, a framed screen securely attached to and overlapping the top of the base, and a seating surface attached to the top of the framed screen. The base, made of granite, concrete, or the like, is relatively massive, providing resistance to vehicular and explosive force. The frame portion of the framed screen, made from structural steel, reinforces the structural integrity of the base, and, along with the screen (and potentially the seating surface) acts to repel or absorb explosive force or debris.
