Abstract: A leg extension apparatus mounted to an existing chair leg to level the chair on an uneven ground is provided. The apparatus includes a bracket assembly having a leg bracket, a first shell bracket coupled to the leg bracket and having a first slot, and a second shell bracket pivotably mounted to the first shell bracket and having a first slot, the first and second shell brackets able to pivotably adjust to an open position to receive the leg of the chair and a closed position to permit the leg of the chair to be enclosed within the first slots of both the first and second shell brackets, and a leg slidably mounted to the leg bracket. The leg slidably adjusts to one of a plurality of locking positions to permit an end of the leg to contact the uneven ground, thereby supporting the chair in a leveled position.
