Quick verdict

Most modern foam, latex, and hybrid mattresses need a firm, even support surface such as a platform, foundation, or closely spaced slats. A traditional box spring is mainly relevant for mattresses designed to use one.

Platform beds

Platform beds support the mattress with slats or a solid deck, often without a separate foundation. Check slat spacing, center legs, weight capacity, and whether the surface supports the mattress warranty.

Box springs

Traditional box springs contain springs and were designed for older innerspring systems. They can flex too much for many foam or hybrid mattresses unless the manufacturer specifically allows them.

Foundations

Modern foundations often look like box springs but are rigid. They add height and support without bounce. Retail terms can be sloppy, so inspect the actual construction.

Before buying

Confirm mattress support requirements, finished bed height, under-bed clearance, airflow, center support, and whether the base can handle the combined weight of mattress, sleepers, and bedding.
