A head restraint guide assembly mounted into apertures formed in a seatback (14) frame for receiving support posts of a head restraint. The head restrai nt guide (40) allows for incremental adjustment and locking of the height of th e head restraint relative to the seatback (14) frame. The guide assembly (40) has opposite upper and lower ends. A center bore extends between and through both of the upper and lower ends. The guide assembly (40) comprises a generally cylindrical main body having upper and lower portions. A lip is formed in the upper portion adjacent to the lower portion. A lattice of structural ribs (60) extends outwardly from the upper portion and extends between the lip and the upper end of the guide assembly (40). The lower portion comprises a pair of symmetrically opposite and spaced apart legs (62 ) that extend downwardly from the upper portion. The legs (62) are elastically inwardly displaceable. Each leg includes a ramped surface to facilitate insertion into the seatback (14) frame. Each ramped surface terminates at a locating edge. The lip and the locating edge together serve to axially locat e and lock the guide assembly in the apertures of the seatback.
