Chair
Armrests

A chair may or may not have armrests; chairs with armrests are termed "armchairs". In French, a distinction is made between fauteuil and chaise, the terms for chairs with and without armrests, respectively. In Germany, an armchair was once called a Krankensessel, or sick-chair, because it was intended for people who were too ill to stand or sit without extra support.

If present, armrests will support part of the body weight through the arms if the arms are resting on the armrests. Elbow rest height is used to determine the height of the armrests. Armrests should support the forearm and not the sensitive elbow area. Hence in some chair designs, the armrest is not continuous to the chair back, but is missing in the elbow area. Armrests further have the function of making entry and exit from the chair easier (but from the side it becomes more difficult).
