The design may be made of porous materials, or be drilled with holes for decoration; a low back or gaps can provide ventilation. The back may extend above the height of the occupant's head, which can optionally contain a headrest.

Chair seats vary widely in construction and may or may not match construction of the chair's back (backrest).
