Seat ideas welcome

Had the Thruxton R for 9 days and its great. OK so every now and again I will require a pillion seat so I enquired and was told that the double Thruxton seat is on back order until October... ok so great excuse not to take the wife buit actually just means I get less riding time. So I thought will any other seats fit or is it only a specific Thruxton seat?? Will the seat off a another model fit - does anyone know..? Thx Andy
