Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.

A stool and desk support system. The system includes a stool base and a desk support surface. A support member may connect the desk support surface to the stool base and support the desk support surface above a floor surface. The stool base may include a stool seat surface and a rocking mechanism opposite the stool seat surface. The desk support surface may be connected to a desk support base by a neck extending from the desk support base. The stool base may include an upper stool base frame and a lower stool base frame. The upper stool base frame may be height adjustable with respect to the lower stool base frame. The desk support base may connect to the upper stool base frame, permitting coinciding height adjustment of the desk support surface and the upper stool base frame.

A seating assembly for athletes includes seats having a back and seat portion, a base, an adjustable element, a user interface device, and a controller. The back portion includes a back heating member that provides heat to a user's torso. The seat portion includes a lower limb heating member that provides heat to the user's lower limbs. The base supports each seat. The adjustable element is coupled to the base and one of the seats and adjusts height of the seat. The user interface device receives an input regarding a desired temperature of the back heating member and the lower limb heating member. The controller receives the input and adjusts an operation of the back heating member and the lower limb heating member to achieve the desired temperature. The user interface device receives a second input to adjust the a height of the seat relative to the floor surface.

A pivoting mechanism with a first member, a second member pivotally engaged with the first member to pivot about a pivot axis, and pivoting resistance mechanism with a spring housing disposed in the first member spaced from the pivot axis, a spring disposed in the spring housing, and a deflecting member that projects from the second member spaced from the pivot axis to engage the spring disposed in the spring housing. The first member can be a chair mechanism body, and the second member can be a pivoting support, such as for a chair bottom or back. A height adjustment mechanism has a movable member, and a locking member, such as a screw, can be operative as a height locking mechanism with a first, restraining condition wherein actuation of the movable member is prevented and a second, non-restraining condition wherein actuation of the movable member is permitted.

An exercise chair allows a user to obtain physical exercise at his or her desk or other workplace. An exemplary exercise chair may include a frame, including a base, an angled section angled upward from the front of the base, and a back support extending upward from the rear of the base; a seat support rotatably connected to the angled section; and at least one resistance element connected to a rear portion of the seat support and to the back support.

A footrest device for supporting feet apart from a cylinder includes a central hub, an outer ring spaced apart from the central hub, and spars, each extending radially from a proximal end, on the first jaw of the hub, to a distal end on the ring. The hub is a clamp with an open condition and a closed condition for clamping onto the cylinder, and it includes first and second jaws pivoted to each other to open and close the hub about a space configured to receive the cylinder. A latch assembly opens and closes the first and second jaws with respect to each other.
