Can this mattress go on an adjustable base or a box spring?

Yes to both. This firm tight-top is rated compatible with adjustable bases; its 815 pocketed coils flex independently so head and foot articulation works, and that does not void the 10-year warranty. No box spring is required, but it needs a firm, even foundation: a platform, slatted frame with narrow gaps, solid foundation, or adjustable base all work. Avoid a sagging or wide-slat base, which can undermine the coil support.
