A double bed is a type of bed designed to accommodate two people. It typically measures 54 inches wide by 75 inches long, providing enough space for couples to sleep comfortably. Double beds are popular in homes, hotels, and guest rooms, offering a balance between size and comfort. In addition to the standard double bed, there are variations such as the full bed and the queen bed. While a full bed is similar in size, a queen bed is larger, measuring 60 inches wide by 80 inches long. These options cater to different preferences and room sizes.
