The Casper Foundation is the perfect option for the Metal Bed Frame. Should you opt for an alternative foundation or box spring, choose one with sturdy, unyielding slats with a lot of surface area spaced 4 inches apart or less - these are often described as "modern style." Foundations in this style will provide the correct support for both you and your mattress.
