The HMI Deluxe Wood Foundation from Capitol Bedding is one of the strongest wood foundations produced. The HMI vertical cross slat frame network used in all versions offers unparalleled strength and durability, arranging the cross slats vertically like the floor joists in a home in the middle third. This is a non-flexing foundation, with 3.5″ cross slats spaced only 3″ apart. It’s offered in gray suede ticking. This HMI design was created by Capitol Bedding founder Al Beuerle, and is hand-crafted in their Grand Ledge factory. This foundation is used for all of our Capitol Bedding products.
