Most people replace a pillow when it stops feeling right. They spend time reading reviews, comparing options, making a decision. Then the new one arrives, and it is either too flat or too thick, and the whole process starts again.
The pillow was not necessarily the problem. The setup was.
Almost every pillow in the Martian Made range ships with removable fill. You can take fill out, put more back in, and change the height and firmness in minutes without tools, without fuss, and without spending anything. Most people who own one of these pillows do not know this is possible. Most people who own a pillow from any brand do not know it is possible. That is the gap this article is here to close.
Step 1: Work out what your pillow is actually doing wrong
Before you touch the fill, be clear about the problem. There are really only two.
The pillow is too high
Your head is pushed forward, your neck bends up toward the ceiling (if you sleep on your back) or tilts toward your shoulder (if you sleep on your side). You might wake with a stiff upper neck or a dull ache behind the shoulder blades.
The pillow is too low
Your head drops, your neck sags, and the muscles along the side of your neck work all night to compensate. This tends to show up as tension across the base of the skull in the morning.
Knowing which one you have matters because the fix is different. One requires removing fill; the other requires adding it back. Skipping this step means you are adjusting at random, and random adjustment is just expensive guesswork.
Step 2: Understand what the right height actually means for your position
Loft is the technical term for pillow height, and the right loft depends entirely on how you sleep.
Side sleepers
Need the most. Lying on your side, the pillow has to bridge the gap between your head and the mattress, which is roughly the width of your shoulder. If it does not reach, your neck bends downward. If it overshoots, your neck tilts upward. The target is a straight line from the base of your skull to your tailbone, with your ear sitting directly above your shoulder.
Back sleepers
Need considerably less. Your shoulders are flat against the mattress, so the gap the pillow needs to fill is much smaller. Too much height here pushes the chin toward the chest and creates tension through the front of the neck. A flatter, softer position is almost always better for back sleeping than people expect.
Front sleepers
Need the least of all. Ideally, almost nothing. Sleeping face-down with a thick pillow forces the head to one side and the neck into a sustained rotation for hours. If you sleep on your front, removing most of the fill is not a compromise. It is the correct choice.
Keep this in mind as a reference point for every adjustment that follows.
Step 3: Locate and open the fill access point
Every adjustable pillow has an inner cover with a zip or an opening that gives access to the fill. On Martian Made pillows, the inner cover sits inside the outer protector cover. Unzip the outer cover first, then find the inner one.
Do not rush this. The inner zip runs around one end of the pillow, and the fill will shift toward the opening as you start to work with it. Have something ready to put the removed fill into: a pillowcase, a zip-lock bag, or a clean carrier bag. You will want to keep it, because you may need it back.
Step 4: Remove fill in controlled amounts
This is where most people go wrong by doing too much at once.
Pull out a modest handful, no more. For a shredded memory foam fill like the LunaCore Hybrid or the StarFirm, this will come out in loose clumps. For a microfibre fill like the Velistra, it will come in softer, lighter sections. Either way, the principle is the same: small amounts, assessed each time.
Close the inner zip after each removal. Then hold the pillow upright and squeeze it. Feel where the weight sits, whether the fill has redistributed evenly, and how much give there is in the centre. Then lay it flat on your bed and press down with your forearm, roughly the weight of a head. Does it compress to almost nothing? Too little fill. Does it barely move? Still too much.
You are looking for a pillow that compresses with firm pressure but springs back promptly and holds its shape when you lift your arm.
Repeat until the pillow feels roughly right when you hold it in position. Then stop. You will not know for certain until you sleep on it.
Step 5: Sleep on it, actually sleep on it, before adjusting further
One night is not enough data.
The first night on any changed sleep setup involves novelty, and novelty affects how you experience comfort. Sleep on the adjusted pillow for two consecutive nights before deciding whether more adjustment is needed. If you wake both mornings with the same stiffness or the same ache, that is meaningful. If the second morning is better than the first, give it a third night before touching anything.
Keep the removed fill nearby and accessible. Do not throw it away.
The temptation after one uncomfortable night is to pull out more fill, or to put it all back, or to order something entirely new. Resist all three. Two nights of consistent evidence is the minimum before your next move.
Step 6: Fine-tune based on what you actually felt
After two nights, you should have enough to work with.
If the stiffness is at the base of the skull or across the upper back, the pillow is still too high. Remove another small amount and repeat the two-night test.
If the tension is in the side of the neck, or you woke with your arm underneath your head trying to prop yourself up (side sleepers do this unconsciously when the pillow is too flat), add some fill back. Not all of it. Half of what you removed, or less.
If you genuinely cannot tell, the pillow is probably close enough and the issue lies elsewhere, possibly the mattress firmness, possibly sleep position, possibly something that has nothing to do with the pillow at all.
A pillow that fits well tends to make itself known by its absence. You stop noticing it.
Step 7: Store the removed fill properly
This step gets skipped more than it should.
The fill you have removed still has value. Keeping it means you can reverse any adjustment, re-loft the pillow after the fill compresses over months of use, or transfer it to a travel pillowcase when you need something lightweight.
A sealed zip-lock bag or a small vacuum storage bag works well. Label it if you have more than one pillow in the house with removable fill, which, once you have done this once, you very likely will. Somewhere dry, away from direct sunlight, away from anything that might compress it permanently.
Do not leave it loose in a drawer. Loose microfibre or shredded foam left in an open space will pick up dust and lose its loft before you get around to using it again.
Step 8: Know when the adjustment has worked
There is no single moment of certainty. What you are looking for is the gradual disappearance of the symptoms that brought you here.
The neck stiffness that was a daily feature becomes occasional, then goes. The habit of reaching up to reposition the pillow at two in the morning stops. You start sleeping through rather than surfacing at odd hours and rearranging the bedding. None of these things announce themselves.
That absence, quietly, is the signal.
One last thing worth saying: most people who go through this process once will never buy a pillow without checking for removable fill again. The difference between a pillow that fits and one that almost fits turns out to matter rather more than most people expect, and "almost fits" is where an awful lot of pillows live.
If you want to explore the Martian Made range and find the right starting point for your sleep position, the pillow range is built as a firmness ladder, from the soft and plush Velistra to the structured support of the StarFirm, with every pillow in it adjustable from the day it arrives.
