A chair can include armrest apparatuses. Each of the armrest apparatuses can be configured so an arm pad is connectable to an armrest without the use of a mechanical fastener (e.g. a screw, a bolt, etc.) and without the use of an adhesive or welding, and without the use of mechanical tools (e.g. screw driver, hammer, etc.) by use of interlocking mating profiles defined in the structure of the arm pad and structure of the armrest to which the arm pad is attached. Embodiments of the chair can be configured as a side chair, task chair, or other type of chair having at least one armrest or other type of armrest apparatus.

A seat cushion provided for supporting a sitting person, including a seat portion having an upwardly facing surface and a downwardly facing surface; a plurality of mutually spaced inclined grooves formed in the seat portion; wherein the inclined grooves extend along at least a portion of the distance between the upwardly facing surface and the downwardly facing surface.
