Hull Amount
Same fill as the Buckwheat Pillow

Pre-polished, air-jet cleaned, UV-sterilized USA-grown buckwheat hulls. The same hulls we put in our Buckwheat Pillow.
How to use it

Open the zipper on the short end on your existing pillow. Pour in hulls until the loft sits where you want. The bag re-seals so you can save extras for next time.
Pre-polished for quieter hulls

Our hulls run through a patented air-jet polishing process that breaks the sharp pyramid corners into individual flat sides. That cuts the rustle by up to 68% compared to unpolished hulls.
Air-jet cleaned, UV-sterilized

Hulls are pre-polished, air-jet cleaned, then UV-sterilized, and never treated with a synthetic pesticide, chemical wash or fire retardant, so none of it ends up under your head.

The same pre-polished USA-grown buckwheat hulls we use in every Circadian Buckwheat Pillow, available as a standalone refill. Buckwheat hulls gradually break down under the weight of nightly use, and when they do, the pillow loses its firm cervical support. Most people get three to five years from a hull load before refreshing it. Topping up the hulls, or fully replacing them, brings the pillow back to day-one feel without replacing the whole thing.

Standard buckwheat hulls are rough three-sided pyramids, and roasting them is what makes imported hulls crumble faster. Ours are never roasted. They go through a patented air-jet cleaning process that breaks them into flatter single-sided polished pieces. That reduces movement noise by up to 68 percent and makes the surface softer against the skin, without changing the flex-and-lock support buckwheat is known for. Grown and air-jet processed in the United States.

What you get

Available in 1, 3, 5, 10, 20, 50, 100, and 200 pound bags.

How to use it

Open the zipper on the short end of your Circadian Buckwheat Pillow and add hulls a few handfuls at a time. Test the height and firmness after each round, because buckwheat is dense and small additions make a real difference. Side sleepers usually want it fuller, for the firm high support buckwheat is best at.

Shipping

The hulls ship within the United States only. Every pillow we make goes worldwide, but this one is loose agricultural material in bags up to 200 pounds, and we keep it domestic. If you are outside the US and your Circadian buckwheat pillow needs topping up, write to me and we will sort something out.

Certification

The hulls are UV sterilized with no chemicals and never roasted. Like most buckwheat hulls on the market, they carry no organic certification. What sets ours apart is the air-jet cleaning, which takes out the dust, so less of it reaches the air you breathe.

How many hulls you need

Hulls are heavy next to every other material we sell, so a buckwheat pillow holds three to four times the weight of a wool or cotton one. These are the weights we build each size to:

Pillow Dimensions Weight with cover
Buckwheat Travel 12" x 16" 2.5 lb
Buckwheat Standard 20" x 26" 10 lb
Buckwheat Queen 20" x 30" 13 lb
Buckwheat King 20" x 36" 15 lb
Buckwool Standard 20" x 26" 8 lb

Which means 1 lb or 3 lb is a top-up for a pillow that has lost some height. 5 lb refills one side of a Buckwool or a couple of travel pillows. 10 lb rebuilds a Standard from empty. 20 lb does a King with some in hand. Everything above that is for people filling several pillows or building their own.

Hulls do not wear out the way a fiber does. They flatten and lose their spring over years, and a top-up mixed through the old ones brings the height back without replacing the lot.

Return it within 60 days if the bag is unopened.

Polished USA-grown hulls, air-jet and UV cleaned.

Quick answers

How much hull do I need to refill a pillow?
It depends on the size of your pillow and how much loft has compressed. A Standard buckwheat pillow weighs about 10 pounds with its cover when full. Most refill jobs use 1 to 3 pounds. Start small and add a handful at a time until the loft sits right.
Can I use these hulls in any buckwheat pillow?
Yes. The hulls work in any zippered buckwheat pillow, ours or another brand. Open the zipper on your existing pillow and pour in as many hulls as you want to restore the loft. The hulls are pre-polished and air-jet cleaned the same way as the fill in our Buckwheat Pillow.
How often should I refill a buckwheat pillow?
Most people top off every three to five years. The hulls slowly break down under nightly head weight and the pillow loses some loft. You will feel it before the cover shows it. Add a handful at a time until the height matches your shoulder width when you lie on your side.
Are these hulls pre-polished?
Yes. The hulls are pre-polished and air-jet cleaned in our proprietary process, which breaks the sharp pyramid corners into individual flat sides. That cuts the rustle by up to 68% compared to standard buckwheat hulls and prevents sharp edges from poking through your cover. They are then UV-sterilized without chemicals.

Where are the buckwheat hulls grown?

USA, on regional farms. Buckwheat crowds out its own weeds and pests rarely bother it, and ours grows without synthetic pesticide treatment.
