US Box Spring Promo Codes & Coupons September 2026 — Up to 20% Off

As a manufacturer of sleep products, after 30 years, people will find their eyes need better products. In 2007, one of its online customers approached US Box Spring with a request for a base for their premium latex mattresses. It stepped in, identified the customer's needs, built a foundation that was superior to any other company in the market, and made it affordable. It increases the number of slats, providing more support for each mattress by reducing the open space between slats to less than 3 inches, which has become the industry standard. It also improved the quality of the wood and polished a smooth sand surface on all four sides of each piece, then covered the foundation with all-organic cotton. US Box Spring chose to retain the traditional two-piece foundation for all oversized mattresses.
