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.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A synchronous-tilt reclining office chair includes a seat, a backrest interconnected to the seat, and an arrangement providing a synchronous-tilt mechanism that controls synchronous movement of the backrest and seat between a normal non-reclined position and a reclined position. Recline tension provided by the arrangement is a function of a force required to compress at least one tensioning spring mounted below the seat, a weight applied on the seat by a seat occupant, and a location of the weight on the seat relative to front and rear portions of the seat, whereby, as the weight is applied toward the front portion of the seat, recline tension is reduced and, as the weight is applied toward the rear portion of the seat, recline tension is increased.

A chair assembly includes an arm assembly that includes an armrest supported by a vertically adjustable support assembly and an arm base, where the arm base extends at an acute angle with respect to a longitudinal centerline of the chair assembly, an upholstery arrangement including a ring member attached to a cover, where the ring member includes a plurality of reliefs having a width that reduces as the ring member is wrapped about a shell member of the chair assembly, and a control arrangement having a biasing member that moves through an arcuate path as the biasing member is adjusted between varying bias settings.

Stackable or nestable single person seating assemblies that include a leg support defined by a plurality of legs and a crossbar that extends between the plurality of legs. The seat assembly includes a back that is rotatably coupled to the plurality of legs and a seat that is rotatably coupled to the back. A biasing element extends from the leg support to the seat and is coupled to a respective leg. Respective portions of the biasing element provide a third pivot axis and a fourth pivot axis that are activated when the back is reclined relative to the seat.

A seat assembly includes a fabric component having a seat surface and a frame including an interior segment directly attached to the fabric component. The interior segment extends from an exterior segment that has a greater flexural resistance than the interior segment.

An element of a device, in particular an element of a seating furniture assembly or of a seating furniture assembly component is provided. In addition, a device for an item of seating furniture, in particular a seating furniture assembly, for example a pivot mechanism, has an element of this type. Furthermore an item of seating furniture having a device of this type or having an element of this type is possible. In order to simplify the construction of items of seating furniture, the use of a deformation element which is integral, that is to say integrated into the device, which is deformable, which is composed preferably of a plastics material, and which serves as an energy storage member, is proposed.
