Down Pillows Guide: Goose vs Duck, Fill Power vs Fill Weight, Allergies, Washing and Lifespan
Quick answer: down pillows are filled with the soft undercoating of geese or ducks. Fill power measures loft and quality, while fill weight determines firmness. Goose down has higher fill power and costs more than duck down. Synthetic fill is the usual recommendation for allergies, and many down pillows can be machine washed in cool or warm water and dried on low for hours.

A down pillow feels light, soft and lofty, and it can last for years. But terms like fill power, goose, duck and “down alternative” confuse shoppers, and allergy claims are murky. This guide explains the basics: what down is, fill power versus firmness, goose versus duck, allergies, washing, cost, lifespan and how to choose. This is not medical advice. If you have allergies, ask a doctor.
What Is Down?
Down is the soft, fluffy cluster layer beneath the feathers of waterfowl such as geese and ducks. Feathers are the flatter outer parts with quills. Pillows labeled “down” can contain pure down or a down-and-feather blend. “Down pillows” in many stores are blends (for example 50 percent down, 50 percent feathers). Soak and Sleep sells 80 percent goose down pillows. A pillow with more down is softer and more expensive. Saatva’s down pillow guide explains the differences.
Fill Power vs Fill Weight
Sources say: Fill power determines quality. One seller says the fill power determines quality, and the fill weight determines firmness. Fill power measures how much space an ounce of down fills (loft). Higher fill power means larger down clusters and better insulation and loft (general knowledge). Fill weight is how much down is in the pillow. A pillow with more fill weight is firmer.
So a high fill-power pillow with low fill weight is soft, and the same fill power with more fill weight is firm. Another seller says duck down pillows are a good option for those who prefer a firmer pillow.
Goose vs Duck
Goose down has higher fill power, and goose down is a more expensive fill because geese are larger animals and so their down clusters are larger. It is lofty and long-lasting. Duck down is cheaper but compresses faster and needs more fluffing, per one source.
Fill-power ranges conflict. One source puts duck down generally at 400 to 600, while another says duck down typically falls in the 300 to 600 range. Puffy and Pure Parima publish goose versus duck comparisons. Compare the labels, not the animal alone.
| Feature | Goose down | Duck down |
|---|---|---|
| Fill power | Higher | Lower |
| Price | Higher | Lower |
| Loft | Lofty | Slightly flatter |
| Fluffing | Less | More |
Allergies
Synthetic fill is the usual recommendation here, since one source says synthetic pillows cost less and are hypoallergenic. A goose-down seller claims its pillows are super clean, making them a safe choice for allergy sufferers. That is a vendor claim, not independent evidence. Down allergies are often reactions to dust mites or residue. If you have asthma or allergies, ask an allergist. Use a pillow protector and wash covers often. See the pillow cases and how often should you wash your sheets guides for allergen control.
Firmness and Sleep Position
Key points: soft down pillows suit stomach and some back sleepers; medium suits back sleepers and combination sleepers; firm (more fill weight) suits side sleepers.
Down compresses, so side sleepers may need a firmer fill or a gusset (side panel). Check the product’s firmness rating.
Washing and Care
Many down pillows can be machine washed, but it is essential to follow the manufacturer’s instructions closely. For goose down: One guide advises use cold or warm water, never hot. Goose down takes longer to dry than duck down pillows, and one source suggests two to three hours in a residential dryer at low heat. Use dryer balls to fluff the fill. Dry completely to avoid mildew.
Mattress Miracle covers how to wash goose down pillows by detergent, temperature and fill power. See the can you wash pillows guide for general steps.
Daily care: fluff regularly, air out occasionally and use a pillow protector.
Cost and Lifespan
Pillows with 800 to 900+ fill power often exceed $150 each, per one source. Duck down is cheaper but compresses faster and needs more fluffing. Synthetic pillows cost the least up front. Entry-level pillows can last 10 to 15 years with proper washing and care, per one seller. Another says even the best goose down pillow will need replacement after roughly 10 to 20 years.
These are seller figures. A simple test: fold the pillow in half. If it does not spring back, it is time to replace it.
Ethical Considerations
Down is an animal product. Look for responsible sourcing labels such as the Responsible Down Standard (general knowledge, verify with the certifier) if this matters to you.
Size
Down pillows come in standard, queen and king sizes. See the standard pillow size guide for dimensions and the pillow cases guide for case fit.
What are the main strengths and weaknesses?
On the plus side: soft, lofty and luxurious; moldable; long-lasting when cared for; breathable. On the downside: expensive; not ideal for some allergies; needs fluffing and careful washing; animal product; can be too soft for side sleepers.
How to Choose Down Pillows
Decide soft, medium or firm. Check fill power for quality. Check fill weight for firmness. Choose goose or duck by budget. Check the percentage of down vs feathers. Consider allergies; ask a doctor. Check the shell fabric and thread count. Check care instructions. Check the sleep trial and return policy. Read reviews.
What mistakes should you avoid?
A few common mistakes are worth avoiding: confusing fill power with firmness; assuming “down pillow” means pure down; using hot water; not drying fully; skipping a pillow protector; trusting vendor allergy claims.
