Short answer

Memory foam holds a consistent shape, distributes pressure and does not flatten overnight. In exchange it sleeps warmer, feels firmer and slower than fibre, cannot usually be machine washed, and often has an initial smell. Solid foam has a fixed loft; shredded foam trades some support for adjustability.

The tradeoffs

Pros

  • Keeps its profile through the night instead of collapsing.
  • Spreads pressure across a wider contact area.
  • Can be moulded into supportive shapes.
  • Long service life relative to cheap fibre pillows.

Cons and unknowns

  • Retains more body heat than fibre or latex.
  • Firmer, slower response some sleepers dislike.
  • Solid cores should not be machine washed.
  • New foam commonly off-gasses for a while.
  • Fixed loft unless the fill is shredded.

Who may prefer another fill

Choose latex if you want a quicker, springier response; fibre or down if you want to fold and scrunch the pillow; or adjustable shredded fill if exact height matters more than a sculpted surface. Solid foam is strongest when consistency matters and weakest when flexibility, coolness or washability matters.
