I have a couple of Flites spare but only really want to sell one. It is super comfy but VERY tatty with holes in the leather at both corners (came on a second hand bike, I didn't do it honest!). You could get it reupholstered or, if super hard, take off the leather and padding and ride on the plastic base.
Let me know if this sounds any good and I'll get you a photo.
Cheers
Ed
