Need a sturdy, low-profile base for your full-size mattress? This 4-inch high box spring gives you solid support without adding much height to your bed. It's split into two sections, making it easy to maneuver through narrow hallways, stairs, or doorways—just slide each half in and they lock together. Built with a wooden frame and slats, it meets federal flammability standards and works with any mattress type (innerspring, memory foam, hybrid). The white fabric cover looks clean under a bed skirt or fitted sheet. Assembly is minimal—just join the two halves and you're done. Made in the USA with quality materials, it's a reliable, affordable foundation that extends the life of your mattress. Perfect for guest rooms, kids' beds, or any setup where you want traditional support without a bulky box spring.
