A transformable sewing surface for sewing machines formed of a base consisting of a first section having an upper and lower surface, a second section containing stitch-forming members, extending parallel to the first section and spaced from it, and a platform connected to said first section so as to swing with respect to it in order to assume two positions, in the first of which it is located in the space present between the sections of the base so as to form a continuous sewing surface with it while in the second position it turns with respect to the first section so as to leave the second section free, the connection of the platform being provided with hinges of flexible material by means of which the platform can turn so as to be swung from the first position in which it rests on the lower surface of the first section to the second position where the platform rests on the upper surface of the first section.
