A securement device for releasable attachment of a lapboard to a user's leg includes a table member and a pair of in-folding leg members, one each of which is attached for hinged movement relative to a corresponding side edge portion of the table member. Elastic webbing interconnectes the free end portion of each leg member to a central portion on the underside of the table member. The securement device is centered on a user's leg with the leg members bracing the table member to prevent displacement thereof a result of ordinary unbalanced imposed forces. When removed from a user's leg, the securement device folds to a compact storage position flush with the table member.
