(FORTUNE Magazine) – Figuring that business travelers spend most of their time in hotels asleep, both Westin and Marriott have been pushing plush beds in their ads. Westin says its campaign has been so successful that parent Starwood is putting similar Sweet Sleeper Beds in every one of its 200 Sheraton Hotels by the end of the year. And both hotels sell fully loaded beds--with pillows, sheets and a comforter--to enamored customers (now that's room service!). We took Westin's Heavenly Bed and the Marriott Bed for a test rest at each chain's location in New York City's Times Square. --Julia Boorstin
