Hullo Buckwheat Pillow Review
Hullo · Buckwheat · Firm · Tested over three weeks by the Mr. Squish team



The Hullo is a traditional buckwheat pillow: US-grown organic hulls inside a twill cotton case with a zipper for adding or removing fill. It's about as far from a foam pillow as bedding gets.
Buckwheat is a genuinely different sleeping experience — firm, cool, contouring in a mechanical rather than a squishy way, and it makes a soft rustling sound when you move.

Firmness and feel
Firm, and unlike anything else in this lineup. Hulls shift out from under pressure and then lock into place, so the pillow molds to your head and then stays exactly there — no slow sink, no rebound. Most people either love it by night three or return it.
Support by sleep position
Side sleepers get outstanding support because the hulls simply don't compress; you can build as much height as your shoulder needs. Back sleepers should remove hulls until the head sits level.
Stomach sleepers can strip it very low, though a soft pillow suits that position better.
Cooling performance
The coolest pillow we've tested. Air moves freely through the hull mass, so body heat never accumulates. If your main complaint is a hot pillow, buckwheat solves it outright.
Materials and construction
A heavy cotton twill case with a full-length zipper, stuffed with cleaned organic hulls. The case is built like workwear — Hullo backs it with a lifetime guarantee — and extra hulls are sold by the pound.
Adjustability
Total control. Pour hulls out into a bag for a lower loft, buy more for a taller one. There is no other pillow format that lets you set loft this precisely.
Durability and care
Hulls last a decade or more and can be aired in the sun to refresh. The case is machine washable once emptied. Note the weight: a queen Hullo weighs around ten pounds.

Who should buy it
Hot sleepers, side sleepers who need real firmness, and anyone who has never found a pillow supportive enough.
Who should skip it
Anyone who wants a soft, quiet, lightweight pillow.
How we tested it
Every pillow in our library goes through the same routine: three weeks of nightly sleep across side, back and stomach positions, loft measured under a 10 lb head-weight load, surface temperature checked at lights-out and again after six hours, and a wash cycle to see how the cover and fill hold up. Scores above reflect that testing, not manufacturer claims.
Comparable pillows
Final verdict
A niche pillow that's the outright best option for the people it suits. If heat and sagging support are your problems, buckwheat ends both.
Mr. Squish score: 8.7/10
