Best Mattresses for Platform Beds
Platform beds use a solid or slatted surface instead of a box spring, which changes the feel and requirements of the mattress above. Most modern foam and hybrid mattresses work perfectly on platform beds — they don't need the additional spring of a box spring. However, innerspring mattresses designed for box spring use may feel too firm or lose coil feel on a flat platform. We selected mattresses that perform well on platform surfaces and don't require a box spring or bunkie board.
How We Ranked
- ✓Works on solid or slatted platform (no box spring required)
- ✓Compatible with standard slat spacing (3 inches max)
- ✓Good pressure relief on a firm base
- ✓Medium or firmer feel (5+) for proper support without springboard effect
