A pivot base for a computer monitor includes a base member, a monitor supporting member and a releasable retaining unit. The base member has a top side and a pair of mounting plates that project upwardly at the top side and that are spaced apart in a transverse direction. The monitor supporting member is adapted for mounting the computer monitor thereon. The monitor supporting member is mounted movably between the mounting plates, and is movable relative to the base member in a first direction for locating the computer monitor in a generally upright position and in a second direction for locating the computer monitor in an inclined position. The releasable retaining unit is provided on the base member and the monitor supporting member to arrest relative movement therebetween.
