The exercise ball chair stabilizes an exercise ball so that it can be used as a comfortable chair. While seated in the exercise ball chair, a user may perform seated-workout exercises. The exercise ball chair comprises a left support, a right support, and a ball retainer. The ball retainer pivots between a ball retention position and a ball release position. An exercise ball is placed in the chair such that the left support, the right support, and the ball retainer, in the ball retention position, capture the exercise ball and prevent it from rolling. A user may then sit on the exercise ball. A left adjustment knob and a right adjustment knob allow the ball retainer to be locked to prevent it from pivoting. With the adjustment knobs loosened, the ball retainer may be pivoted to the ball release position and the exercise ball may be removed.
