BBC One is to broadcast Graham Norton's Big Red Chair, a special episode of The Graham Norton Show that "goes behind the scenes of TV's most famous comfy chair to meet the people who have entertained the nation with their stories. Sometimes."

Due to be broadcast in early January, the episode will tell the story "of how this precarious flippable piece of furniture came to be a universally loved feature of his show and has played host to some amazing audience anecdotes".

The producers explain: "Each week, Graham's celebrity guests have watched open mouthed as daring audience members have gripped the red chair tightly and told their story, all the while, hoping not to be flipped.

"Allowing the best storytellers to walk, Graham has judged over 500 red chair stories. Many have walked, most have been flipped, and for some it has been life changing. And so, whilst musing the art of telling the perfect red chair story, Graham showcases his all-time favourite stories."

Graham Norton's Big Red Chair will be broadcast on BBC One on Friday 6th January at 10.35pm.
