Serta Platform Foundations, also known as Bunkie Boards, are 2” thick sturdy platforms made of wood, covered in fabric, designed to provide support and stability for a mattress. They are commonly used on bunk beds, platform beds, or daybeds. Bunkie boards are placed directly on top of a metal bed frame or the wooden slats of a traditional bed frame underneath the mattress. They help distribute weight evenly, prevent sagging, and increase the lifespan of the mattress by providing a solid foundation. Bunkie boards are often used in situations where a traditional box spring or foundation may not be practical due to space constraints or mattress height preferences. They are available in all standard sizes to accommodate different bed frames and mattress types.
