A chair facilitates both rocking and bouncing. The chair includes a base adapted to support a seating portion, the seating portion having a surface adapted to be sat on by a user. The seating portion has a bouncing mechanism, such as an exercise ball. A rocking mechanism is provided to cause the base to rock. The rocking mechanism facilitates the rocking back and forth of the user when the user is seated on the seating portion, and the bouncing mechanism facilitates the bouncing of the user when the user is seated on the seating portion. The bouncing is in a bouncing direction that is different than the direction of rocking. The chair is particularly useful for calming a baby and/or for facilitating stimming.
