Memory foam pillow pros and cons

Memory foam can provide a stable shaped surface, but its slow response and density feel very different from loose fiber, down or latex.

Pros

• Can hold a molded contour.
• Stable feel with little fluffing.
• Many densities and shapes are available.

Cons

• One-piece foam is not loft-adjustable.
• Some sleepers dislike the dense, slow-response feel.
• Heat perception varies.
