B-77 was a very luxurious outward First Class State Room, laying amidships, on the starboard side of B-Deck. It was decorated in the Harland & Wolff Bedroom 'B' style. it was half-panelled in white and oak dado. The furniture was common throughout First Class and included a double wash cabinet, a dressing table and a sofa. This perticular cabin had a walk-in wardrobe and there was a shared bathroom facility which was also used by B-75 which was directly next to it.
The Countess of Rothes and her niece Gladys Cherry occupied this cabin during the voyage and could not find a lifejacket in the room on the night of the sinking.
