A king bed frame is a large bed frame designed to support a king mattress, which typically measures 76 inches wide by 80 inches long. This size provides ample space for couples or individuals who enjoy extra room while sleeping. King bed frames come in various styles, materials, and designs, including wood, metal, and upholstered options. In addition to providing support for the mattress, a king bed frame often includes features such as built-in storage drawers or a headboard. Many frames are designed to accommodate a box spring, while others are compatible with adjustable bases, enhancing comfort and functionality in the bedroom.
