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 like 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, a bed frame can enhance the overall aesthetic of a bedroom. Some frames include built-in storage options, such as drawers or shelves, making them functional as well as decorative. A sturdy bed frame can also help prolong the life of a mattress by providing proper support.
