Claim:
An armrest for a seating unit comprising: an armrest support adapted for attachment to a seating unit; an armrest cap adapted to support a person's arm, said armrest cap comprising a lower cap member and an upper cap member; a pair of swing arms supporting the lower cap member on the armrest support, each swing arm being pivotally attached at a first location to the lower cap member, and each slidably-and-pivotally attached to the armrest support for adjustably supporting the armrest cap for independent longitudinal, lateral, and rotational adjustment including movement between a forward position where at least half the armrest cap is forward of a midline of the armrest support and a rearward position where at least half the armrest cap is rearward of a midline of the armrest support; and a friction-increasing mechanism attached to at least one of the first locations to increase frictional force resisting horizontal movement of the armrest cap and swing arms when adjusting the armrest cap on the armrest support wherein the friction increasing mechanism comprises a wave compression spring positioned above the lower cap member.
