A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand, walk or work for an extended period without requiring the user's arms to hold the frame. A motorized drive helps the user move with ease. The drive can be computer controlled.

Seating furniture, in particular, a chair having a plane of symmetry, a seat surface, a backrest, a kinematic arranged on a base of the seating furniture, which has a base arm, which is rotatable relative to the base around a base axis (A1), an end arm, which is rotatable around a base arm around an intermediate axis (A2), and a furniture part that is mounted to rotate around the end arm around an end axis (A3), where the three axes (A1, A2 and A3) intersect at a central point (Z, Z1). To achieve versatile mobility, the pivotable furniture part is the backrest, that the seat surface is mounted to rotate relative to the backrest around a connection axis running orthogonally to the plane of symmetry, and that the seat surface is connected to the base via a support kinematic that constrains at least one degree of freedom.

A seating apparatus for supporting a portion of a user, the seating apparatus comprising a reorientable seat portion including a seat platform and a cutout, wherein the seat selectively underlies a first ischial tuberosity of the user but not the second ischial tuberosity, the selection of which is determined by the orientation of the reorientable seat portion.

An office-type chair includes a base, a height-adjustable pedestal extending upward from the base, a seat assembly including a rear seat part and a front seat part, and a linkage system connecting the pedestal to the seat assembly. The linkage system is adapted to pivot the seat assembly between a lowered position to serve as a task chair and an elevated position to serve as an elevated sitting support. A backrest arrangement may extend from the seat assembly. In the lowered position, the front and rear seat parts are both generally horizontally oriented. In the elevated position, the rear seat part may have a slight forward tilt and be positioned higher than in the lowered position, and the front seat part may extend at a downward angle relative to the rear seat part.

A seating arrangement includes an upwardly-extending back arrangement movable between upright and reclined positions, and a seat arrangement that includes a first link member extending horizontally and having forward and rearward portions, a second link member spaced from the first link member, a third link member coupled to the first and second link members and substantially flexible along a majority of a length thereof, and a fourth link member operably coupled to the first and second link members, the fourth link member being substantially rigid along a majority of a length thereof, wherein the link members cooperate to form a four-bar linkage assembly, and wherein the seat arrangement moves in a rearward direction as the back arrangement is moved between the upright position and the reclined position.
