A bed frame is a fundamental piece of furniture that serves as the foundation and support for a mattress, box spring or any sleeping surface. It usually consists of a metal or wooden structure with four legs, two side rails and a headboard to hold the mattress in place while providing stability and preventing it from sagging. The bed frame can be made of various materials such as wood, iron, steel, brass, aluminum or even plastic, depending on personal preference and style. It is an essential component that ensures a good night's sleep by offering proper support to the mattress and providing comfort while lying in bed.
