Your Shoulder Decides the Pillow

Lie on your side and a gap opens between the outer edge of your shoulder and the side of your head. It is not a mood or a preference. It is a distance, particular to your frame, and the pillow either fills it or it does not. Almost everybody chooses by pressing one with a hand in a shop, which measures nothing at all.

Your hand is not your neck, and a pillow under a palm is not a pillow under a head that weighs five kilos and has to stay level for eight hours.

Height, not softness

The wider the shoulder, the further the head sits from the surface, and the taller the pillow has to be to keep the neck in line with the rest of the spine. Too low and the head drops toward the mattress. Too tall and it is pushed the other way. Both end in the same place, which is a neck held slightly off its line all night by something that felt fine in the shop.

Softness cannot fix either one, and this is the part that gets missed. A soft pillow compresses to whatever height your weight decides, which is rarely the height you needed. The measurement that matters is the height it holds at four in the morning, not the height it has when you put your head down.

Pressing a pillow with one hand in a shop measures nothing.

The profiles, and who each one is for

Seven sit across a narrow range, and the differences are smaller than people expect and matter more than they assume. Five centimetres separates the lowest from the highest, which sounds trivial until it is the five centimetres holding your neck out of line until morning.

• The 03: a sculpted cervical slope moving between 10 and 11.5 centimetres, for back sleepers and for narrower shoulders that find most pillows push the chin toward the chest.
• The 04 and The 05: 12.5 centimetres, a middle profile for anyone who moves between back and side through the night.
• The 07: 14 centimetres on a compact 60 by 40 footprint, for side sleepers in a room where a full-width pillow crowds the bed.
• The 01 and The 02: 14.5 centimetres, for the broader shoulder that side-sleeps most of the night.
• The 06: 15 centimetres in a 55 by 55 square, the tallest profile, and the one that also stands up against a wall to read against.

All seven are GOLS certified organic latex under the same taupe bamboo casing, so the decision really is only about profile.

Why the number holds

Latex answers weight by pushing back rather than by giving way. Press a palm into it and the surface returns the moment the hand lifts, so a 12.5 centimetre pillow is still close to 12.5 centimetres at three in the morning, with a head on it. The shoulder underneath is not being slowly lowered onto the mattress across the night while the geometry quietly goes wrong.

That is most of what pressure relief means for a side sleeper. Not a softer landing, but how long the correct geometry lasts. A material that holds its structure keeps the load spread across the whole shoulder instead of concentrating it, hour after hour, at the one point where the pillow gave way first.

Measuring instead of guessing

Stand with your back against a wall, let your arm hang, and have somebody measure from the wall to the side of your neck. That figure, less a little for how far your shoulder sinks into the mattress, is roughly the pillow height you are looking for.

The mattress is part of the sum, which is why the answer is not the same for everybody with the same shoulders. A firm surface lets the shoulder sink less and asks for a taller pillow. A yielding one asks for less height than you would guess.

It is a small piece of arithmetic done once, and it replaces about a decade of buying pillows by hand and hoping.
