A joint assembly has a housing having an inner wall surrounding an interior cavity of the housing. A slider is held captive in the interior cavity of the housing so as to define an annular volume extending radially between the slider and the inner wall of housing, the slider constrained to planar movement and a rotational degree of freedom in the housing. An annular resilient member is in the annular volume, the annular resilient member exerting a biasing force between the slider and the housing toward a neutral configuration. The housing is adapted to be connected to one of a ground/base/motion platform and a linear actuator, and the slider is adapted to be connected to the other of the ground/base/motion platform and the linear actuator.

A multipurpose workout chair is an exercising equipment that not only can be used for workout training, but also can be used as a chair. The multipurpose workout chair includes adjustment devices and other components acting with each other which allows the multipurpose purpose chair to be changed into various configurations according to different training methods and each of the training methods may be executed by one or more different muscles.

Seating furniture includes at least a first and a second linear actuator to adjust the seat part, the foot part, and the back part between the seating and the reclining position. The first linear actuator generates a linear stroke causing the back part to be adjusted relative to the seat part. The second linear actuator generates a linear stroke having at least a first and second partial stroke, The first partial stroke causes, during adjustment of the seating furniture from the seating position into the reclining position, the seat part to slide relative to the frame towards the front, and simultaneously the inclination of the seat part to be adjusted, there being no extension or retraction of the foot part relative to the seat part during this first partial stroke of the second linear actuator. The second linear actuator causes the foot part to extend relative to the seat part by a second partial stroke following the first partial stroke.

Various aspects of the present disclosure are directed to adjustable chairs with a plurality of adjustment points to facilitate enhanced user mobility and increase a user's physical activity through guided exercises and stretches. In one example embodiment, a chair is disclosed including a lifting mechanism to assist a user from a seating to a standing position and facilitates standing stretches through a number of motion and rotation mechanisms.
