Head-to-head · Beds & Foundations
Platform Bed vs Box Spring
Slat support vs traditional foundation
Platform Bed
Slats support the mattress directly — lower profile, no extra purchase.
Box Spring / Foundation
A separate support layer — taller stack, required by some innerspring warranties.
The call
Foam and hybrid mattresses want a platform or rigid foundation with slats 3 inches apart or less — a springy old box spring can void the warranty. Traditional innersprings may still require a box spring for theirs. Read the mattress warranty first; it decides this head-to-head for you.
