Once Upon A Mattress, presented by Collision Care Xpress, is a musical comedy based upon the beloved fairytale, The Princess and the Pea. The lords and ladies of the kingdom are unhappy because Queen Aggravain has decreed that no one is allowed to marry until her adult son, Prince Dauntless has found a suitable princess to wed. Each petitioning princess is tried with difficult tasks to test different aspects of her worthiness. All princesses have failed and been sent away thus far. Sir Harry, desperate to marry the Lady Larken, ventures out to the far reaches of the land to find a new princess. One night, Harry brings back a very unique and seemingly unrefined Princess Winnifred, who intrigues Dauntless and the court. However, the Queen finds her completely unbecoming and creates a seemly impossible test to pass: a pea placed underneath twenty mattresses to test sensitivity. If Winnifred sleeps soundly, she fails. Will she pass this unreasonable test and wed Dauntless? Never judge a book by its cover.
