What is Fill Power?

If you’ve ever shopped for a comforter or duvet, you most likely ran across the term “fill power”. But what exactly is fill power and why is it important? In this blog post, we will explore the concept of fill power and how it affects your sleep.

What is Fill Power?

Fill power is a measurement used to determine the weight and loftiness of down and down alternative bedding. It refers to the amount of space that one ounce of down or down alternative occupies in cubic inches when it is allowed to reach its maximum loft. The higher the fill power, the better the insulation and the more air the bedding can trap, resulting in a warmer and more comfortable sleep experience.

How is Fill Power Measured?

Fill power is measured by placing one ounce of down or down alternative in a graduated cylinder and then measuring the volume it occupies. The higher the volume, the higher the fill power. Fill power is typically measured on a scale ranging from 450 to 900, with the 600 range holding superior loft and fluff.

Why is Fill Power Important?

Fill power is an important factor to consider when choosing bedding because it directly affects the warmth, comfort, and durability of the product. Bedding with a fill power around 600 provides better insulation than a comforter with a fill power of 300, allowing you to stay warm and cozy during colder nights. Additionally, bedding with better fill power tends to be more durable and long-lasting, as it retains its loftiness and fluffiness for a longer period of time.

What Fill Power Should I Choose?

The ideal fill power for your bedding depends on your personal preferences and the climate in which you live. However, a fill power around 600-700 is the perfect balance that provides adequate warmth without sacrificing breathability. If you live in a colder climate or tend to get cold easily, a higher fill power, such as 700 or above, might work for you. On the other hand, if you’re a hot sleeper or live in a warmer climate, a lower fill power, such as 500 or below, may be more suitable.
