The Heavy Duty SmartBase® is a mattress foundation even stronger than your Monday morning coffee. Engineered precisely with heavy duty steel and unwavering support from multiple points of contact with the floor, this frame is built tough enough to support up to 4400 lbs of evenly distributed weight. With a frame this sturdy, you can bet that your mattress will be optimally supported for the long haul with absolutely no sagging. Its metal platform effortlessly supports your foam, spring, or latex mattress without the need for a box spring. Built with over a foot of valuable under bed space for extra storage, this handy frame also includes practical features like recessed legs and plastic caps to protect your floors. And although the last thing you’d expect from a frame this tough and functional is tool-free assembly, that(and a 5-year worry-free warranty, no less) is exactly what it comes with. Easily unfold the base, extend the legs, use the easy locking system to secure everything in place, and voila! You’ve got a substantial mattress frame in less time than it takes to brew that pot of coffee.
