Lucky buggers.
I'd give anything to sit in a Diary Room Chair, especially BB9's or BB7's.
I bet Mario is like 'Wahaay let's come back to my place people you can all sit in my chair but it costs 10 Quid'
I'd actually charge people about 30 Quid or more to enter my house to sit on that chair if I had it.
I'd have a full on sign out the window 'SIT IN THE BIG BROTHER 7 DIARY ROOM CHAIR RIGHT HERE'
They'd be lining up.
