A wheeled chair for assisting a user in changing a disposition. The chair comprises: a base member, a substantially planar seat member, a leg bracing member, a back bracing member, a bracing motor, and an actuator module. The base member includes a plurality of wheels and a lift device. The seat member is oriented substantially orthogonal to the direction of motion of the lift device. The leg bracing member includes a first mode wherein it extends downwardly from the seat member and a second mode wherein it extends substantially collinearly from the seat member. The back bracing member includes a first mode wherein it extends upwardly from the seat member and a second mode wherein it extends substantially collinearly from the seat member. The bracing motor changes between the two modes. The lift device includes a lift device motor. The actuator module activates the bracing and lift device motors simultaneously.
