An automatic upward lifting device, and a furniture article having an automatic upward lifting device. The automatic upward lifting device comprises a base (1), an upward lifting mechanism (2) rotatably provided at the base (1), a cushioning mechanism (3) installed at the base (1), an adjustment mechanism (4) used to adjust a cushioning force of the cushioning mechanism (3), and a drive mechanism (5) used to drive the upward lifting mechanism (2) to rotate. The adjustment mechanism (4) is rotatably provided at the base (1), and presses against the upward lifting mechanism (2). The upward lifting mechanism (2) acts on the cushioning mechanism (3) via the adjustment mechanism (4). The device has a simple and compact structure and a practical design, and achieves automatic rotation of the upward lifting mechanism, thereby reducing the amount of labor required for the rotation of the upward lifting mechanism, and improving the intelligence of the device. The adjustment mechanism can be used to adjust the strength of the cushioning force of the cushioning mechanism according to an actual cushioning force requirement, thereby achieving adjustability of the cushioning level of the cushioning mechanism. The invention is easy to adjust and highly practical, and operates in a safe, stable, and reliable manner.
