Bed supports are an essential part of a bed frame, and they come in two main forms: LEGS and SLATS. LEGS are four-letter supports that are typically made of wood or metal and are attached to the bed frame. SLATS are five-letter supports that are usually made of wood or metal and are placed across the bed frame to provide additional support. Both LEGS and SLATS are important for providing stability and support to the bed frame, ensuring that it can hold up the mattress and any other items placed on it.
