What is the meaning of the furniture term Truckle Bed?

A truckle bed, also known as a trundle bed, is a type of bed that consists of two separate beds, one underneath the other. The lower bed is on casters or wheels and can easily be rolled out from under the upper bed when needed.

This design allows for efficient use of space and provides an extra sleeping area that can be conveniently stored away when not in use. Typically, truckle beds are used in smaller bedrooms, childrens rooms, or guest rooms to accommodate additional sleepers without taking up excessive space.
