A furniture system includes an office productivity structure (OPS). The furniture system also includes a sensor coupled to the OPS, the sensor operable to detect occupancy of the OPS and generate an output signal indicative of the occupancy; and a processor coupled to the sensor. The processor is operable to receive the output signal generated by the sensor, determine, based on the output signal, that the OPS is occupied, and, in response to determining that the OPS is occupied, generate a command to initiate at least one action associated with the OPS or an operator of the OPS.

A chair includes, a seat, a backrest separated from the seat, and an upper support frame to which the backrest is attached at a position higher than the seat. In the chair, the upper support frame includes a left side portin and a right side portions both extending forward at left and right sides of the seated person and a rear portion that continuously and integrally connects the left side portion and the right side portion. The left side portion and the right side portion are connected to side support bodies arranged on left and right sides of the seat to be tiltable, and the backrest is connected to the upper support frame to be tiltable rearward.

A folding mechanism for a chair and, in particular, to a stairlift chair, has a seat base, backrest and armrests. The folding mechanism ensures that all parts of the chair remain in a swivel arc whether the chair is in an in-use configuration or folded configuration. Various additional features are described including armrests formed in part by flexible straps.

A seat connection mechanism having a bracket portion which is metal and includes a pivot area, an opening and a channel. A metal pin portion includes a pin and a stop portion, the pin rests in the pivot area such that the shelf portion inhibits movement of the pin portion along the pin's rotation axis, the pin configured to rotate within the pivot area about a rotation axis. The channel in the bracket portion arranged to pass adjacent and through an area of the center pivot, the channel arranged such that the stop portion of the pin portion are insertable into the channel through the opening at an insertion angle to allow the pin to rest in the pivot area and such that when the pin rotates within the center pivot, the stop portion of the pin portion moves within the bracket and the stop portion is configured to interact with the bracket at one or more predefined positions to stop rotation of the pin portion.

A seat with self-stowage capability is provided. The seat includes a seat pan lever which is rotatable between stowed and open positions, a fixed seat structure and an elastic assembly. The fixed seat structure includes an annulus. The elastic assembly includes a damper and an arc-spring disposable within the annulus to permit first rotations of the seat pan lever from the stowed position to the open positions and to urge second rotations of the seat pan lever from the open positions to the stowed position.

In some implementations, a self-cleaning seat includes a cover layer with a photocatalyst; a light-emitting fiber layer including one or more light sources; a light-diffusing spacer configured to diffuse light emitted from the light-emitting fiber layer and positioned between the cover layer and the light-emitting fiber layer; and a triggering mechanism that activates a cleaning cycle by activating the one or more light sources.
