A support for an armrest assembly includes a plurality of interconnected ribs. One or more of those ribs has (a) a first section, having a first proximal end and a first distal end, (b) a second end section, having a second proximal end and a second distal end, and (c) an intermediate section connecting the first distal end and the second distal end. The first end section and the second end section are offset. An armrest assembly includes a body, the support, a cushioning layer overlying the support and a cover layer overlying the cushioning layer.
