The present invention relates to a lifting seating device, including a seat assembly, a lifting assembly and a base assembly which can be placed on the ground. A lower end of the lifting assembly is mounted to the base assembly, and an upper end of the lifting assembly is connected to the seat assembly. The lifting seating device further includes an elastic shielding cover arranged to circle a side surface of the lifting seating device. Upper and lower ends of the elastic shielding cover are respectively coupled to the seat assembly and the base assembly. The elastic shielding cover extends and retracts with the lifting of the seat assembly under the action of the lifting assembly. The lifting assembly is arranged between the seat assembly and the base assembly, the elastic shielding cover is arranged, and upper and lower ends of the elastic shielding cover are respectively coupled to the seat assembly and the base assembly. Thus, the base assembly and the lifting assembly are covered by the elastic shielding cover to achieve a simple and attractive appearance. Meanwhile, the elastic shielding cover extends and retracts with the lifting of the seat assembly under the action of the lifting assembly, so that a chair also has a lifting function.

The present application relates to a chair which adapts to dynamic body postures of a user. The posture adaptive work chair includes a seat sub-assembly having a front edge and a seat base sub-assembly; a pair of spine members cantilevered from the font edge of the seat sub-assembly; a back sub-assembly supported by the pair of spine members, and configured to flex in multiple axes based on a direction of load applied by a user; and a tilt limit lever movably coupled to the seat base sub-assembly and configured to enable tilting of the back-sub assembly to a plurality of tilt positions.

A resettable pressure bar module includes a pressure bar, a rotation element, and a resetting element. The pressure bar includes an outer tube, an upper sealing element, and a lower sealing element. The upper sealing element and the lower sealing element are disposed in the outer tube and respectively disposed on the opposite two sides of the outer tube. The rotation element is fixed to the outer tube and the lower sealing element through a fixing element. One side of the resetting element includes a first guiding slope and a second guiding slope. The pressure bar passes through the resetting element. The rotation element is configured to rotate to a normal position along the first guiding slope or the second guiding slope.

The adjustable bathtub/shower seat includes a support and a backrest pivotally attached thereto, a base attached to the support, and a controller in communication with the support, the backrest, and the base. Advantageously, the base is selectively raised and lowered along a vertical path. Advantageously, the backrest is selectively pivoted about a horizontal fulcrum axis and along an arcuate path, wherein the horizontal fulcrum axis is registered orthogonal to the vertical path.
