What back sleepers actually need
The gap between your head and the mattress when lying on your back is smaller than most people expect — roughly 5–8 cm for adults. The goal is to fill that gap so the cervical spine stays in its natural gentle curve, not pushed forward or dropped back. Most standard pillows on the high street are designed for a combination sleeper and sit too high for a dedicated back sleeper, which is why many back sleepers unconsciously flip to their side overnight.
The three factors that matter most
1. Loft — medium, not high
A compressed loft of 6–9 cm suits most back sleepers. Smaller-framed sleepers need the lower end; broader-shouldered people (who have more shoulder width to account for even when on their back) need slightly more. Avoid anything marketed as 'high loft' or designed for side sleepers — these push the head too far forward.
2. Cervical support
Back sleepers benefit from a pillow that has slightly more fill at the base (where the neck sits) than at the top (where the head rests). Contour memory foam pillows are designed exactly for this. Alternatively, a medium-firm standard pillow that doesn't collapse under head weight achieves a similar result.
3. Softness that doesn't compress
Back sleepers often prefer a softer feel than side sleepers, but softness must not come at the expense of support. Down and hollow-fibre pillows can feel wonderfully soft initially but compress to near-flat under head weight if fill power is low. Look for high fill-power down (600+) or a well-rated hollow-fibre that holds its loft.
Best fill types for back sleeping
Memory foam contour pillows are the most reliable choice for back sleepers who prioritise alignment — they hold a fixed shape all night. Standard memory foam is denser and heavier; shredded memory foam is adjustable and slightly more breathable. Natural down suits back sleepers who run cold and want a softer feel, provided the fill power is high enough to avoid compression. Latex offers a springy, resilient feel and lasts longer than foam, but its fixed height means you need to choose the right loft before buying.
What to avoid
Pillows labelled 'firm' without height context
A firm pillow is only useful if it's also the right height. A firm but over-thick pillow creates the same alignment problem as a soft one — just for a different reason. Firmness and loft are independent properties; you need both to be right.
Sleeping without a pillow
Some back sleepers try removing the pillow entirely. This is only appropriate for stomach sleepers. For back sleepers, no pillow means the head drops back and the cervical curve collapses. A low-loft pillow is always better than nothing.

Frequently asked questions
What height pillow is best for back sleepers?
Most back sleepers do best with a compressed loft of 6–9 cm — medium height. Contour memory foam pillows are designed specifically for this position and take the guesswork out of choosing a loft.
Should back sleepers use a soft or firm pillow?
Medium is the sweet spot for most back sleepers. Soft can feel comfortable but may compress too far. Firm is only suitable if the loft is also correct for your head and neck size.
Can back sleeping cause neck pain?
Poor pillow choice can cause neck pain regardless of position. For back sleepers, the usual culprit is a pillow that's too thick, pushing the chin forward. If you wake with neck discomfort and switching to a medium-loft pillow doesn't help within two to three weeks, see a GP or physiotherapist.
Is memory foam or down better for back sleepers?
Memory foam is more reliable for alignment because it holds its shape. Down is more comfortable for those who prioritise feel and run cold, but you need a high fill-power down (600+) to ensure it doesn't compress flat under head weight.
