Abstract: Top panel height adjustable furniture (1) includes a top panel (2) that has an upper surface (3) and a lower surface (4); a support body (5) that is connected to the top panel (2) and is capable of extending or contracting in a panel thickness direction of the top panel (2); a sensor (11) that detects contact of a user on the upper surface (3) side of the top panel (2) and contact of the user on the lower surface (4) side of the top panel (2); and a control unit that controls, based on a detection result of the sensor (11), an extending/contracting operation of the support body (5) such that the support body (5) contracts when it is detected that the user has made contact with the top panel (2) on the upper surface (3) side of the top panel (2) and that the support body (5) extends when it is detected that the user has made contact with the top panel (2) on the lower surface (4) side of the top panel (2).
