Comparative Literature:
Sylvie Chadenet, Les Styles Empire & Restauration, Paris, for a very similar armchair without the ebony inlay on the back in the Musée Marmottan, illustrated p. 58, no. 2 and described as Consulat reproduced here in fig.1.
Jean-Pierre Samoyault, Mobilier Français Consulat et Empire, Paris, 2009, p. 27, figs. 25 & 26, illustrates in fig. 25 a design by Charles Percier and Pierre-François-Léonard Fontaine for various projects for seat furniture for the firm of Jacob, circa 1795, where an armchair en curule of almost identical form is illustrated, reproduced here in fig. 2.

Also see Samoyault, op. cit., p. 27, fig. 26, for an armchair of identical form to the offered pair, attributed to Georges Jacob for  the Tuileries under the Consulat around 1795.

This elegant and refined model reflects the taste for the revival of Antique curule chairs during the late 18th century reflected in the x-form shape of these chairs. The excellent quality of the carving and originality of design bear all the hallmarks of the outstanding menuisier Georges Jacob.

This model was also known to have been also stamped Jacob Frères.

Georges Jacob received Master 1765.
Jacob Frères Rue Meslée was the stamp used by Georges II and François-Honoré-Georges Jacob from 1796-1803.
