Buckwheat yoga bolster: is a hull-filled bolster right for you?

We research products from makers' specs and health sources; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.

Quick answerA buckwheat yoga bolster is filled with buckwheat hulls, the hard outer shells of the seed. The hulls shift and settle around your body, so the bolster molds to you while staying firm, and many designs let you add or remove hulls through a zip to change the firmness. The trade-off is weight: one maker's full-size bolster averages about 4.5 kg, roughly double the 5.0-pound cotton bolster compared below. Choose one with a removable, washable outer cover.

How buckwheat feels compared with other fills

Buckwheat hulls behave like a bag of tiny, light shells. Press into the bolster and they move aside, then hold their place. Brow Farm, a UK maker, says its bolster molds to your body shape.

Buckwheat hullsFirm, shapeable, slight rustleYes, add or remove hullsAbout 4.5 kg (Brow Farm)
Cotton batting with foam coreFirm, springy, holds a set shapeNo5.0 lb (Hugger Mugger Standard)

Converted, 4.5 kg is about 9.9 pounds, so the buckwheat example weighs roughly twice the cotton one. That weight makes a buckwheat bolster very stable on the floor, but it is a lot to carry to class.

Adjusting and caring for the hulls

  1. Set the firmness. Unzip the inner case over a large bowl or bag and remove a little at a time. Keep spare hulls in a sealed bag in case you want them back.
  2. Wash the cover, not the hulls. The makers above describe machine-washable covers but do not say the hulls can be washed. Keep the inner case dry.
  3. Air it out. Fluff and shake the bolster now and then so the hulls do not pack down in one spot.
  4. Store it flat and dry. Damp is the enemy of any natural fill, so keep it off a cold floor in a garage or basement.
  5. Check the zips. A split seam on the inner case means hulls everywhere; close the zip fully after every adjustment.

If you like buckwheat for sleep, the same material shows up in pillows; see buckwheat pillow for neck pain.

Buckwheat or something else?

If you want one bolster that you can carry and use for every pose, a cotton or fiber rectangular bolster is simpler. If you practice mostly at home and value a bolster that shapes to you, buckwheat is worth the weight. Compare shapes in rectangular vs round yoga bolster and fills in our main yoga bolster guide.

Cotton-filled rectangular bolster

Best for: Anyone who wants a lighter, firm bolster without the rustle

When to talk to a doctor: If you are allergic to buckwheat, choose a different fill. A full buckwheat bolster is heavy (Brow Farm lists about 4.5 kg), so get help moving it or choose a lighter bolster if lifting is hard for you. If you are pregnant, older or have a health condition, NCCIH advises talking with your provider before yoga, since some poses may need changing.

Questions people ask

Are buckwheat yoga bolsters good?
They suit home practice well: firm, stable and adjustable. Their weight makes them less handy to carry.
How heavy is a buckwheat bolster?
Heavier than most. One maker lists its full-size bolster at an average of about 4.5 kg, which is about 9.9 pounds.
Can you wash a buckwheat yoga bolster?
Wash the outer cover as the label allows. Neither maker cited here says the hulls can be washed, so keep the inner case dry.
Can I make a buckwheat bolster firmer or softer?
Yes, if it has a zipped inner case. Add hulls for a firmer, taller bolster or remove some for a softer, lower one.
Is buckwheat or cotton better for restorative yoga?
Both work. Buckwheat shapes itself around you and can be adjusted, which suits long, still holds. Cotton holds a fixed shape, weighs less and is quieter, which suits people who move their bolster around a lot.
Do buckwheat bolsters make noise?
Yes, a little. The hulls rustle when they shift, so the sound is most noticeable while you move into or out of a pose.
