A table includes collapsible telescopic legs and a height adjustment mechanism. The height adjustment mechanism includes a pair of latch arms and an activation device. When pushed downward, the activation device engages with the latch arms to cause the latch arms to move inward. The inward motion is opposed by a biasing mechanism disposed between the latch arms. As the latch arms move inward, tabs at the ends of the latch arms disengage from notches on the telescopic legs to allow the legs to be extended or retracted. When the activation device is released, the tabs engage with the notches to lock the legs at a selected height position.
