Kapok Guide

Thin Pillow for Stomach Sleepers, Adjustable Kapok

The short answer

Stomach sleepers need the lowest pillow of anyone, because the head has nowhere to go but up. A kapok pillow that opens with a zipper lets you take fill out until it sits low and soft instead of hunting for a thin pillow that is still too tall. Most stomach sleepers end up using about half the fill.

Why stomach sleeping is the opposite problem

On your side, a pillow has to fill the whole gap between your shoulder and your ear. On your stomach, there is almost no gap at all. Your head is already close to the mattress, so anything tall pushes your neck up and back for the whole night. That is why most stomach sleepers go through pillow after pillow and end up with a flat old one, or none at all.

The usual advice is a thin pillow. The trouble is that thin is a fixed height someone else chose. What works better is a pillow you can take fill out of until it sits where you want it.

Why kapok works for it

Kapok is a silky plant fiber from the seed pods of the ceiba tree. Each fiber is hollow, which makes the fill light, soft and springy (more in What Is Kapok?). Two things about it matter for stomach sleepers:

  • You control how much there is. Our pillow ships full and opens with a hidden zipper. Take out a few handfuls and it drops to a low, soft loft that a block of foam can never reach. Most stomach sleepers settle around half the fill.
  • It moves with you. Loose fill flattens under your cheek and leaves the rest of the pillow low and soft, instead of holding one shape all night. If you tuck an arm under the pillow, the fill shifts around it.

How to set it up

  1. Fluff it hard. Kapok compresses in the box. Give it a minute of squeezing and shaking when it arrives.
  2. Take out about a third right away. Stomach sleepers almost never want it full. Work over the bed, pull the fill out in whole clumps, and bag what you remove.
  3. Sleep one night on it. Lying on your stomach, your head should rest low and close to level, not tilted back.
  4. Keep going a handful at a time. If your neck still feels bent back, take out more. It is easier to take more out than to wish you had not.
  5. Keep what you remove. Kapok settles over months, and that bag is how you top it off later. If you ever want it taller, add refill.

My loft guide covers the details for every sleeping position, and the long version is in The Best Pillow for Stomach Sleepers.

Which size to choose

Size changes how wide the pillow is, not how tall it sits. Height comes from the fill, so choose size by the bed and how much you move. Many stomach sleepers like Queen or King because there is room to slide an arm underneath without running off the edge.

Questions

Frequently asked

Is a kapok pillow low enough for a stomach sleeper?
Yes, because you decide how low it goes. Ours ships full and opens with a hidden zipper. Take fill out until it sits where you want it. Most stomach sleepers use about half the fill, and some use less.
Why not just buy a thin pillow?
A thin pillow is one fixed height. If it is still a little too tall, or too flat after a few months, there is nothing to do about it. With loose kapok you can take out one more handful, or add some back from the bag you saved.
What do I do with the fill I take out?
Bag it and keep it. Kapok settles with use, and that bag is how you top the pillow off later. If you run out, a 3 lb bag of refill kapok covers it.
Can I wash a kapok pillow?
Not the filled pillow. Keep it dry, fluff it and spot clean the shell. For a layer you can throw in the washing machine, use the envelope cover or a regular pillowcase. See the care guide.
What if it doesn't work for me?
Every MAREA pillow has a 100 day sleep trial from delivery. Used pillows are accepted and you get a free return label in the contiguous US. The full terms are on the returns page.
