Abstract

A seating device can include a height adjustment mechanism that permits a height of a seat to be adjusted. The height adjustment device can be configured so that a user may provide a force to provide upward height adjustment and may also provide a force to allowing for a controlled downward height adjustment of the seat. The height adjustment device can include an actuator that is connected to a rotatable member via linkages. An end of one of the linkages may engage the rotatable member to prevent rotation of the rotatable member, which can prevent height adjustment of the seat. Movement of the actuator may cause the linkages to move so that the rotatable member is free to rotate so that a user may provide a force on the seat to effect height adjustment of the seat and/or cause the seat to be lowered at a desired speed.
