What is a pullman bed?

A Pullman bed is a type of bed in which one bed is stored beneath another. The lower bed can be pulled out on wheels or a track to create a second sleeping space. This type of bed is commonly used in small spaces such as cabins, dormitories, and hotel rooms to maximize space and provide additional sleeping accommodations. Pullman beds are also popular on trains, cruise ships, and in recreational vehicles. They are typically designed to be compact and easily stowed away when not in use.
