Abstract: Support tables suitable for supporting a computer keyboard in front of a user and adapted for rotatable attachment to the side arms of a chair are provided. Each support table is hingedly attached to the front of each side arm so as to be pivotable about each of two orthogonal axes. The support tables are foldable from a generally horizontal position disposed above the seat of the chair and in front of the chair side arms and the user to a stored position disposed adjacent the outside sides the chair and side arms when the support tables are not in use.
