This queen-size box spring gives your mattress a solid, sag-free foundation. Built from a thickened steel frame, it supports up to 3500 lbs, holding its shape night after night without wobbling or bending. Standing 9.1 inches tall, its high-profile design suits sleepers who prefer their bed higher off the ground, and it pairs well with spring, memory foam, and latex mattresses alike. A removable, shrink-resistant fabric cover keeps the mattress from sliding and lifts off easily for cleaning. Rounded corners on all four sides guard against bumps and scuffs while moving it into place. Measuring 79.1 x 59.6 x 9.1 inches and weighing just 33.07 lbs, it's easy to carry and set up with the included screws, wrenches, and instructions - no headboard needed, making it a fit for bedrooms, guest rooms, hotels, or studio rest areas.
