The term "bed frame" refers to an independent structure that supports the mattress frame. The exact construction of a bed frame varies according to the type, but the typical profile is the height of the bed. If you spend a third of your life in bed, it is best to invest in a good bed frame that lasts for years.
Some bed frames are designed to support the base of the mattress on a foundation, while others are equipped with slats to support it. Most bed frames today are made of wood, metal or a combination of the two materials, and some models are covered in foam or cloth. Some bed frames have padded fabrics for a softer feel, while others have no padding.
