An adjustable armrest assembly includes a support fixed to a chair seat and a sleeve slidably mounted on the support. An armrest is mounted to the sleeve to move therewith. The sleeve is slidable relative to the support to allow adjustment of a level of the armrest. The sleeve can be retained at a desired level relative to the support. An upward force is imparted to the sleeve while the sleeve is slidable relative to the support.
