No, a modern one-sided mattress should not be flipped, because its comfort layers and support core only work in one direction. Rotating the mattress head to foot is the safer way to even out wear.

Should you flip your mattress?
Hybrid and all-foam mattresses stack foam comfort layers over a coil or high-density foam base, so turning one upside down puts the firm support layer under your body and buries the pressure-relief layers. Flipping makes sense only for the rare mattress built with two usable sleeping sides, such as a flippable dual-firmness construction.
- Hybrid mattresses combine individually pocketed coils with 2 or more inches of foam comfort layers on one sleeping side.
- Innerspring mattresses rest on an interconnected coil grid with minimal foam above it, and many are built for a single sleeping surface.
- Flippable dual-firmness construction is the one design where turning a mattress over is intended by the manufacturer.
- Memory foam mattress comfort layers are designed to sit on top of a firmer base layer, not underneath it.
