Six fills, one of them is yours.
Most natural pillow brands sell one fill in three sizes. We sell six because no single material works for every sleeper. Every chapter below tells you the feel, the numbers, and what's worth knowing before you buy.

01 / 06
Organic Cotton
Dense, supportive, familiar. Cotton fiber compresses slowly and evenly over months and years, not weeks, so the pillow you like on night one is still that pillow in year three. GOTS certified across fill, cover, thread, and dye process.
Good to know: cotton is not naturally dust-mite resistant the way wool is. The cover washes, the fill doesn't.

Organic Wool
Every cooling pillow on the market works passively, absorbing heat until it matches your temperature. Wool works the whole night: it wicks up to 30% of its own weight in moisture while staying dry to the surface, and dry is what feels cool. It resists dust mites naturally too, through three properties of the fiber itself.
Good to know: wool isn't vegan. If you want plant-based softness, that's the kapok.

Buckwheat
The hulls flex under your head, then lock together and hold that exact position all night. Air moves between them constantly, which makes this the coolest pillow we make without a single gram of gel.
Good to know: the hulls rustle softly as they settle. Most people tune it out within a week, and our pre-polished hulls are quieter than standard hulls to begin with.

Wild-Harvested Kapok
Kapok is the softest, lightest fill we make, with the loft of down and not a feather in it. Each fiber is a hollow tube that's 80 to 90% air, which is why it sleeps cool and stays lofty, and why people with chemical sensitivities keep finding this pillow.
Good to know: like down, kapok wants a daily fluff. Push the edges to the center to build a mound that molds to your head.

Buckwool Hybrid
Buckwheat on one side, organic wool on the other, an internal divider keeping them separate. The wool side answers the two things people hesitate over with buckwheat, it's softer and quieter, while the buckwheat side keeps all the support and cooling. Each chamber adjusts independently.
Good to know: ten pounds is a lot of pillow. It stays home, it doesn't travel.

Tree-Tapped Latex
Light, bouncy, and responsive, it springs back instead of sinking, from a rubber tree instead of a lab. Slow-pour Dunlop latex in adjustable pieces, open-cell so air keeps moving, certified OEKO-TEX Standard 100 Class 1 with an FSC-certified tree source.
Good to know: if you have a latex allergy this pillow is a hard no, look at cotton, kapok, or wool instead.
