1. A portable seat for attachment to a chair to support a child thereon, the portable seat comprising:
a base for supporting the portable seat on a surface, the base having forward and rearward ends;
a clamping arm moveably connected to the base at a first end by a slide block, the slide block being moveable between a first position and a second position and having a guide opening symmetrically arranged about the first axis configured to receive the first end and enable clamping arm movement bi-directionally axially along and rotationally about a first axis; and
a lifting bracket connecting the slide block and the base by a linkage comprising a first link and a second link, each link being pivotally coupled at a first end to the base and at a second end to the slide block, the first link and the second link having different lengths which rotate the slide block and the clamping arm about a second axis, the second axis being orthogonal to the first axis, movement of the clamping arm about the second axis altering separation between a clamping foot disposed at a distal end of the clamping arm and the base enabling a portion of the chair to be clamped therebetween.
