Glee: Mattress

"Mattress", also known as "Once Upon a Mattress", is the twelfth episode of the American television series Glee. The episode premiered on the Fox network on December 2, 2009. It was written by series creator Ryan Murphy and directed by Elodie Keene. In "Mattress", the glee club discovers that they are going to be omitted from the school yearbook. Club member Rachel Berry (Lea Michele) has the team cast in a local mattress commercial in an attempt to raise their social status. Glee club director Will Schuester (Matthew Morrison) discovers that his wife Terri (Jessalyn Gilsig) has been faking her pregnancy. The episode features cover versions of four songs, studio recordings of three of which were released as singles, available for digital download, and are also included on the album Glee: The Music, Volume 2. "Mattress" was watched by 8.15 million US viewers, Glee's series high at that point. It received mixed reviews from critics. The conclusion of the fake pregnancy storyline attracted praise, as did Gilsig and Morrison's acting, however Liz Pardue of Zap2it expressed dismay that so few songs were performed, while Raymund Flandez of the Wall Street Journal deemed "Jump" "the only memorable song of the episode".
