Nine-Inch King Steel Box Spring with Reinforced Slats, Quiet Frame and Removable Elastic Fabric Cover
Nine-Inch King Steel Box Spring with Reinforced Slats, Quiet Frame and Removable Elastic Fabric Cover
A nine-inch king steel box spring raises a lower mattress while creating an even, supportive foundation. Reinforced heavy-duty slats distribute weight across the frame and help limit mattress sagging. The selected king base measures 79.6 x 75.6 inches and is listed for up to 3,000 pounds.
Seamlessly welded support connections reduce movement and noise as sleepers turn. All frame parts, tools and instructions arrive in one compact box for guided assembly. The shrink- and wrinkle-resistant fabric cover uses an elastic edge for a snug fit, helps keep the mattress from slipping and removes for cleaning. Multiple sizes and four height profiles are offered.
