Mattress Foundation Guide: What Goes Under Your Bed?
Choose a compatible platform, slatted base, foundation or adjustable base without undermining mattress support or warranty terms.
A mattress needs a stable, compatible base. The wrong foundation can create sagging, change the feel and potentially affect warranty coverage.
Platform beds
A solid or closely slatted platform can support many foam and hybrid mattresses, but always check the manufacturer’s spacing requirements.
Traditional box springs
Modern foam beds often need a rigid foundation rather than an old-style flexible box spring.
Adjustable bases
Many all-foam and hybrid mattresses are flexible enough for adjustable bases, but compatibility should be confirmed before purchase.
Center support
Larger beds often require strong center support to prevent the foundation itself from bowing.
Bottom line
Use this guide as a decision framework, then verify current specifications, pricing and return terms before buying. Mattress fit is personal, and no single model is best for every sleeper.
