Keenan Metal Mattress Foundation

The Keenan Metal Mattress Foundation definitely meets every expectation you might have for a box spring, plus more! This one-of-a-kind foundation conveniently rolls the box spring and bed frame into one easy-to-assemble piece. Simply place your mattress directly on top of this frame and you’re ready for many well-rested nights to come. Its solid steel framework provides strength and longevity to uphold any mattress, and its clever support legs mean that you don't need a bed frame to reap the benefits of this excellent support system. And as an added bonus, brackets for attaching your own headboard are built right in, so you can personalize the bed to suit your existing décor. A 5 year warranty is included for your peace of mind, and all of the tools, parts and instructions needed for quick and simple setup are packed into one box that ships right to your doorstep. Now that's what we call convenience!
