Mobile upholstery repair for suédine chair

Upholstery repair of Maisons du Monde 'Mira' dining chair in brown 'aged-look' suédine (synthetic suede) with a clean slit about 9 to 10 cm long on the front right edge of the seat, with slightly frayed edges and the foam padding visible. One chair only; the rest of the seat is sound. I am looking for a patch repair rather than a full recover, with the brown colour-matched as closely as reasonably possible.
