Memory Foam Pillows
Memory foam is the most common material in support-focused pillows because it holds a shape. Whether that is a benefit depends on how you sleep.

Solid versus shredded
| Solid (moulded) foam | Shredded foam | |
|---|---|---|
| Support | Even and constant; shape does not change | Varies with how the fill settles |
| Adjustability | None — the loft is fixed | Often removable fill to tune height |
| Airflow | Lower unless ventilated or gel-infused | Generally better between the pieces |
| Feel | Slow sink, contouring | Mouldable, more like a conventional pillow |
| Maintenance | Cover washing only | Needs occasional redistribution |
Heat, and what cooling covers actually do
Dense foam restricts airflow and retains body heat. Manufacturers respond with ventilation channels, gel infusions and knit covers described as cooling. These can improve surface feel; treat specific temperature claims as manufacturer claims unless they are backed by published testing.
Practical buying checks
- Density, where published — it correlates with how well the pillow keeps its shape over time.
- Loft, ideally stated as a measurement rather than "medium". See pillow height.
- Cover removability, because foam cores generally cannot be machine washed.
- Off-gassing — a new-foam smell that usually fades over a few days of airing.
- Certifications, such as foam content certifications, if that matters to you. Check the seller's documentation rather than assuming.
Who it suits
- People who want the same support every night without fluffing.
- Side and back sleepers who need a specific loft held reliably — see pillows for side sleepers.
- Anyone drawn to a cervical or contoured shape, which is almost always foam.
Who may prefer something else
- Hot sleepers who have not got on with foam before; latex or a gusseted fibre pillow may suit better.
- People who like to fold or hug a pillow — solid foam resists both.
- Sleepers who want to launder the whole pillow.
