We perform a systematic search for all possible massive deformations of IIAsupergravity in ten dimensions. We show that there exist exactly twopossibilities: Romans supergravity and Howe-Lambert-West supergravity. Alongthe way we give the full details of the ten-dimensional superspace formulationof the latter. The scalar superfield at canonical mass dimension zero (whoselowest component is the dilaton), present in both Romans and massless IIAsupergravities, is not introduced from the outset but its existence followsfrom a certain integrability condition implied by the Bianchi identities. Thisfact leads to the possibility for a certain topological modification ofmassless IIA, reflecting an analogous situation in eleven dimensions.Comment: 35 page
