No, according to Beautyrest, a mattress is suitable with any foundation that is in good condition and provides consistent support. They specify that suitable options include adjustable bases, solid platforms, or slatted frames.
However, for those using a slatted design, Beautyrest recommends ensuring the slats are spaced no further than 2 inches apart to maintain proper structural integrity.
Failure to use a foundation with proper support risks voiding your warranty.
