A floor brake assembly for an article of furniture includes a base adapted to be affixed to an article of furniture, a plunger having a brake pad at a plunger first end and movable between a first position where the brake pad engages a floor and a second position where the brake pad is free of the floor, a pivot arm rotatably mounted to the base, a first activation arm pivotally mounted to the base, and a second activation arm pivotally mounted to the base. The pivot arm is rotated between a braking position and an unbraking position to cause the plunger to move between the first and second positions by way of the first and second activation arms.
