Definition of Bed Frame

Meaning of the Term as it Pertains to Mattresses

What is a Bed Frame?

A bed frame is the structure that supports a mattress. Also called a bedstead, a bed frame may consist of a headboard, footboard, side rails, or posters. Frames may include one or all of the components mentioned and are typically made of wood or metal. Bed shoppers need to purchase bed frames in accordance with mattress size. Larger beds, like queen and king sizes, require center rails for proper support.

In addition to providing necessary mattress support, the bed frame defines a bedroom's decor. Bed frame designs range from minimal to extravagant, and common styles include platform, storage, and sleigh. Some frames offer room for storage below the bed or include space for an additional mattress, called a trundle bed.
