In order to ensure the utmost support and long-lasting comfort for mattresses, the BR Black Foundations have been expertly crafted. These foundations feature a sturdy spruce framework combined with welded steel material, meeting and surpassing all required fire retardant standards at state and federal levels. Available in standard (9") or low profile (5") heights, these foundations are upholstered in coordinating fabric for a seamless look. Opting for a low-profile foundation may be beneficial to maintain a lower bed height, especially when paired with thicker mattresses or specific headboards.
