In order to enhance the durability and comfort of mattresses, the BR Black Foundations offer a sturdy support system. Crafted with spruce and welded steel materials, these foundations not only meet but exceed fire retardant standards at both state and federal levels. They are made with coordinating fabric and are offered in standard (9") or low profile (5") heights. Opting for a low-profile mattress may be a practical choice for those seeking a sleeker overall bed height or specific headboard requirements.
