Down Versus Down Alternative Fill: Differences and Similarities

Relaxing in bed at the end of a long day is even better with a supportive pillow and cozy comforter. When choosing a comforter or pillow, you may wonder which is better: down or down alternative fill? Explore this guide to learn the differences and similarities between down and down alternative—and determine the best comforter or pillow fill option for you. 

Down Versus Down Alternative

The most common fill options for pillows, comforters, duvet inserts, and blankets are down and down alternative. While both fill materials have plenty to offer, consider the key differences between down versus down alternative to help you decide

What Is Down Fill?

The lofty, natural material from the soft under-plumage of ducks and geese is called “down.” Bedding made from down is lightweight and lofty and offers superior insulation and warmth. Fill power can be an indicator of down quality: the higher the fill power, the warmer and loftier the bedding. Additionally, down is naturally breathable, which contributes to more comfortable sleep. Look for products filled with ethically sourced, RDS-certified down to ensure the down was collected following responsible practices for animal welfare. 

What Is Down Alternative Fill?

On the other hand, down alternative fill is a synthetic, down-free fiber designed to mimic the feel and properties of down. Down alternative is often made from a microfiber or polyester fiber and is ideal for people who wish to avoid down products for health reasons or personal preferences. 

Our most popular down alternative fill options are PrimaLoft®, a premium fill that provides excellent down-like comfort with superior moisture-wicking properties, and our exclusive LoftAIRE™, a fiberfill that’s composed of recycled polyester fibers and certified by the Global Recycled Standard. Ultimately, the best down alternative for you depends on your budget, preferred comfort level, and sleeping preferences.

Comparing Fill Options

When choosing between down or down alternative for your comforter, duvet insert, blanket, or pillow, you may consider these factors: 

  • Cost: Down alternative bedding is often less expensive than down bedding. 
  • Allergies: While both down and down alternative are hypoallergenic—and our down fill undergoes a strict cleaning process to remove impurities—allergy sufferers may prefer a down-free option. 
  • Breathability: High-quality down and down alternative fill options offer similar warmth and breathability, but low-quality down alternative fill will be lacking in this area. 
  • Weight: Those who prioritize lightweight, warm, and breathable bedding may prefer a down comforter, while others might choose the more affordable, but slightly heavier, down alternative fill.

  • Care: While down bedding products don’t require any significant special attention, down alternative bedding may be preferred for even easier laundering and care. 
  • Longevity: While down comforters and duvet inserts are crafted to last for decades, down-alternative fibers typically have a shorter lifespan. 

Down Versus Down Alternative Fill Pillows

Both down and down alternative are popular pillow fill material options. Down pillows offer incredible support and are known for breathability and natural moisture-wicking properties. Down alternative pillows provide similar comfort, with a hypoallergenic, synthetic fill. Choosing between the two depends on your individual needs—but no matter which you prefer, a protective cover can help keep allergens out, block spills, and extend the lifespan of your pillow. 

No matter the pillow fill, you have a choice of pillow firmness. Side sleepers may prefer a firmer fill for proper neck alignment, while back sleepers might enjoy the feel of a softer pillow. Ultimately, to find your perfect pillow fill and firmness, consider your usual sleeping position and personal preference for softness or firmness. 

Both down and down alternative fills offer distinct advantages. Ultimately, the best fill material depends on your priorities: Consider factors like preferred comforter or duvet insert warmth and weight or pillow firmness, as well as budget and any personal preferences to help you choose.
