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, a bed frame can enhance the overall aesthetic of a bedroom. Some frames include built-in storage options, such as drawers or shelves, while others may feature adjustable heights. A well-chosen bed frame can improve sleep quality by providing stability and comfort.
