Upgrade Your Sleep with the Zinus Steel Box Spring – Durable, Versatile & Built to Last!

Experience unmatched support and longevity with the Zinus Steel Box Spring, designed to be the last foundation you’ll ever need. Crafted with a solid steel interior frame and wrapped in a sleek knitted polyester cover, this box spring delivers exceptional durability while seamlessly blending with your bedroom decor. Measuring 74 x 38 x 9 inches, it’s the perfect fit for standard twin beds (5 inches shorter than Twin XL), ensuring compatibility with most bed frames—just double-check your dimensions before purchase.

Engineered for strength, this foundation boasts a 350 lb weight capacity (twin size), while larger sizes (full, queen, king) support up to 700 lbs, making it ideal for all sleepers. The pre-assembled design arrives compactly packaged in a single box with all necessary parts and instructions, so setup is quick and hassle-free. Plus, it’s compatible with all Zinus mattresses and most bed frames—though we recommend verifying dimensions for non-Zinus products.

Backed by a 5-year limited warranty, this box spring is an investment in restful nights for years to come. Priced at just $122 (originally $109), it’s a smart, budget-friendly upgrade for your sleep setup. Note: A bed frame is required and sold separately.

Don’t settle for less—choose the Zinus Steel Box Spring for sturdy support, effortless assembly, and unbeatable value!
