The three pillow decisions that matter
Loft (height), firmness, and filling. Everything else - cover material, washability, brand name - is secondary. Get the loft and firmness right for your sleep position and the pillow does its job. Get them wrong and no amount of premium filling saves the situation.
Loft is the gap between your head and the mattress when you're lying in your usual position. Side sleepers have the biggest gap because the shoulder lifts the head further from the surface.2 Back sleepers have a moderate gap. Front sleepers have almost none. The pillow fills that gap and keeps the neck level with the spine. Too high and the neck tilts upward. Too low and the neck drops. Both cause stiffness that no mattress can fix.
Pillow types and what they actually do
Memory foam contour pillows mould to the shape of your neck and head, and the slow response holds the position through the night. Good for back sleepers with neck pain. Bad for front sleepers (too thick) and hot sleepers (traps heat around the face). Memory foam warms up under your head whatever the cover is called; fine in winter, noticeable in summer, and I run hot so I notice.
Latex pillows have a bouncier, more responsive feel that pushes back quickly when you shift. If you change position through the night the pillow adjusts faster than memory foam. Cooler because the open-cell structure breathes. Dunlopillo makes the most widely available latex pillows in UK retail and they pair well with latex mattresses, though they work on any mattress.
Down and feather pillows compress easily and can be shaped by hand, which suits sleepers who adjust their pillow position through the night. The trade-off is they flatten over time and need more frequent replacement. Real down is warmer than synthetic. If feathers set you off, synthetic alternatives mimic the feel.
Hollowfibre and microfibre pillows are the budget workhorse of the category. They don't last as long as foam or latex but they're cheap enough to replace frequently. Cooler than memory foam. Washable in most cases. For a guest room, fine. For your own bed, I'd say no: a fibre pillow is the one place cheap really does feel cheap, and it's flat within the year.
Wool pillows regulate temperature in both directions - warm in winter, breathable in summer. Less common than foam or fibre alternatives but worth looking at for buyers who want natural materials across the whole bed. Woolroom does dedicated wool pillows that sit alongside their mattress range.
Sleep position and pillow pairing
Side sleepers: high loft, firm. The gap between the shoulder and the head is the largest, and anything too thin lets the neck drop sideways. The check I'd do: lie on your side and get someone to look at whether the spine runs straight from the back through the neck - if the head tilts down, the pillow is too thin for that body and mattress.
Back sleepers: medium loft, medium firmness. The pillow needs to cradle the head and support the natural curve of the neck without pushing the chin towards the chest. Memory foam contour pillows are specifically designed for this and they do it well.
Front sleepers: thin and soft, or none at all. If you can train yourself off your front, do; it's the one position I'd talk you out of. A thick pillow when you're on your front tilts the head backwards and rotates the neck all night. If you sleep on your front and have neck pain, the pillow is almost certainly contributing more than the mattress is.
Brand picks
Dunlopillo latex pillows are the best-known latex option in UK retail, and mine is one: I bought cheap for years before switching to a Dunlopillo, and it remains my choice. Latex has a noticeably different bounce from memory foam. Worth trying both if you haven't used latex before.
Simba Hybrid Pillow uses Nanocubes that can be added or removed to adjust loft - one of the few pillows where you can properly customise the height to your exact gap. Useful for buyers who aren't sure what loft they need and want to experiment without buying multiple pillows.
iGel Side Sleeper Deep Pillow through Bensons is purpose-built for the high-loft side-sleeper requirement. The cooling gel in the cover handles the face-warmth issue that memory foam pillows create during the night.
Tempur Cloud pillows use the same slow-response foam as the mattresses and are the best-known memory foam contour pillow for back sleepers with neck issues. The foam is good; the price is Tempur charging for its name, and I'd try the cheaper memory foam contour pillows first.
Common mistakes
Using the same pillow for every sleep position. A side-sleeper pillow is too high for back sleeping. A back-sleeper pillow is too thin for side sleeping. If you switch between the two, either get an adjustable pillow or keep two and swap as needed.
Keeping a pillow until it disintegrates. Pillows lose support faster than mattresses. If yours has flattened or lost its bounce, it's done. Replace more often than you think you need to.
Matching pillow firmness to mattress firmness. A firm mattress doesn't need a firm pillow. The pillow should match your sleep position, not your mattress. A firm mattress with a firm pillow for a side sleeper is a recipe for neck pain because neither the shoulder nor the head has anywhere to settle into the surface.
Verdict
The pillow sets the neck angle. The mattress handles the rest of the spine. Replace more often than you think. And don't spend hundreds on a mattress and ignore what's under your head. If you want a quick steer, work out your ideal pillow height before you buy.
