A bed frame is a structure that supports a mattress and provides a foundation for a bed. It typically consists of a headboard, footboard, and side rails, which can be made from various materials such as wood, metal, or upholstered fabric. Bed frames come in different styles and sizes, including twin, full, queen, and king, to accommodate various mattress dimensions. In addition to supporting the mattress, bed frames can also enhance the overall aesthetic of a bedroom. Some designs include built-in storage options, such as drawers or shelves, making them functional as well as stylish. A sturdy bed frame can improve sleep quality by providing a stable base for the mattress.
