Hullo uses buckwheat hulls inside a zippered cotton case. The fill can be removed and reshaped, but its firm, granular construction is different from the cushioning of foam, down or fiber.
Decide whether that type of fill appeals to you before comparing price. Check the selected size carefully: a small starting-price pillow is not the same purchase as a full-size bed pillow.

$79 Small; $129 Standard; $199 King
Consider Hullo if you want reshapeable hull fill and accept firmness, weight and rustling. Compare a foam or fiber pillow if softness and quiet matter more.
Is this the right fit for you?
Consider it if
You prefer a firm, reshapeable hull fill and want to control the amount inside.
Skip it if
You want a light, quiet, plush pillow.
Height control: Add or remove buckwheat hulls
Hullo lists Small 14 × 20 inches at $79, Standard 20 × 26 at $129, and King 20 × 36 at $199. Size matters when comparing its starting price.

What the hull construction changes
Buckwheat hulls shift when reshaped rather than behaving like a springy block or plush fiber. The amount of fill and how you distribute it both affect the surface. This is a material choice as much as a height choice.
Adjustment without a preset height
Remove hulls into a clean container to reduce fill, then close the zipper and redistribute what remains. Keep the removed hulls so the change is reversible. A universal scoop amount would ignore size, position and mattress differences.
Firmness, weight and sound
Hull fill brings practical trade-offs: a firm granular surface, more weight than many conventional pillows and rustling when moved. Mr. Squish has not established a universal adaptation period or that every sleeper eventually stops noticing the sound.
Airflow and lifespan evidence
Spaces between hulls are part of the construction, but we have not measured an overnight cooling advantage. We also have no documented decade-long lifespan result. Replace or refresh components according to condition and manufacturer guidance rather than a predicted number of years.
Size, care and alternatives
Compare the exact bed-pillow size you intend to buy. Remove hulls before washing the case when instructed; do not assume the fill can go in the washer. Compare the Coop Original if you want removable foam fill, or Saatva Latex if you want a preset-height core assembly instead.

How this review was researched
We have not slept on this pillow. This review is based on manufacturer specifications and our research — published materials, dimensions, care instructions, trial and warranty terms, certifications — plus how those specs compare with pillows we know well in the same category. We do not present any of it as first-hand experience.

Final verdict
Hullo is a different fill format rather than an automatic upgrade over foam. Shortlist it for the reshapeable hull construction, compare the intended size, and evaluate whether firmness and sound are acceptable during the return period.

Frequently asked questions
Is Hullo silent?
No. Buckwheat hulls can rustle as they move. Whether that is distracting is personal; we have not established an adaptation deadline.
How should I change the height?
Remove a small amount of hulls into a clean container, close the case and redistribute the remaining fill. Keep the removed hulls to reverse the adjustment.
Can I wash the hulls?
Do not put the hull fill in the washing machine. Follow Hullo’s instructions for emptying and washing the case separately.
