Crazy enough, the actress who portrays Jenny (Georgia Moffet) has been married or involved with David Tennant (the previous Doctor) because of that episode. Don't they have children too?
As for that chair, I'm willing to bet it really is the same one used in Jenny's episode since the BBC probably put it into the prop warehouse and re-used it for Oswin's first episode. : P
