Choose the right foundation to support your mattress and enhance its longevity. Box springs feature wooden or metal frames with internal springs or grid supports, adding height while absorbing shock and stimulating airflow, and are ideal for innerspring or hybrid mattresses on traditional bed frames. Bunkie boards offer a low-profile alternative at just 1-3 inches thick, providing essential support without added height, and are perfect for memory foam, latex, or hybrid mattresses on platform beds, daybeds, bunk beds, or trundle beds. Both foundations extend your mattress's lifespan when properly matched to your mattress type and bed frame. Explore our entire collection below.
