Down pillows are a popular choice for many sleepers who want a soft, plush and cozy feel. Down pillows are filled with the fluffy clusters of feathers that are found under the outer layer of ducks and geese. Down pillows can provide good support and comfort for your head and neck, as well as regulate your temperature and keep you warm in winter and cool in summer.

However, not all down pillows are created equal. There are many factors to consider when buying down pillows online, such as the fill power, the fill weight, the shell fabric, the size, the shape and the price. Here are some tips to help you find the best down pillows for your needs and preferences.

Fill power is a measure of how fluffy and lofty the down clusters are. It indicates how much space one ounce of down can fill up in a testing device. The higher the fill power, the more air the down can trap and the more insulating and durable it is. Fill power typically ranges from 400 to 900, with higher numbers being more expensive and luxurious. For a down pillow, you may want to look for a fill power of at least 600 to ensure good quality and comfort.

Fill weight is the amount of down that is stuffed into the pillow. It affects how firm or soft the pillow feels. The more down there is, the firmer and heavier the pillow will be. The less down there is, the softer and lighter the pillow will be. Fill weight usually depends on the size and shape of the pillow, as well as your personal preference. For example, a standard size pillow may have a fill weight of 12 to 20 ounces, while a king size pillow may have a fill weight of 18 to 30 ounces.

Shell fabric is the material that covers the down filling and protects it from dust, dirt and moisture. It also affects how smooth and breathable the pillow feels against your skin. The shell fabric should be tightly woven to prevent the down from leaking out or poking through. It should also be soft and durable to withstand frequent washing and use. Some common shell fabrics for down pillows are cotton, polyester or a blend of both. You may also want to look for shell fabrics that are certified by reputable organizations such as Oeko-Tex or Responsible Down Standard (RDS) to ensure that they are free of harmful substances and that the down is ethically sourced.

Size is another factor to consider when buying down pillows online. You may want to choose a size that matches your bed size and your sleeping position. For example, if you have a queen size bed, you may want to get two standard or queen size pillows. If you have a king size bed, you may want to get two king size pillows. If you sleep on your side, you may want a larger pillow that can support your head and neck alignment. If you sleep on your back or stomach, you may want a smaller pillow that can keep your spine in a neutral position.

Shape is also important when buying down pillows online. You may want to choose a shape that suits your sleeping style and comfort level. For example, if you like to hug or mold your pillow, you may want a traditional shape that is rectangular and flat. If you like to fluff or fold your pillow, you may want a gusseted shape that has extra fabric along the edges to create more volume and height. If you like to adjust your pillow’s firmness or loft, you may want an adjustable shape that has a zipper or a drawstring that allows you to add or remove down filling.

Price is the final factor to consider when buying down pillows online. Down pillows can vary widely in price depending on their quality, features and brand name. You may want to set a budget and compare different options before making a purchase. You may also want to look for discounts, coupons or free shipping offers that can help you save money. However, you should not compromise on quality or comfort for the sake of price. Remember that a good down pillow can last for years if properly cared for, so it may be worth investing in one that meets your needs and preferences.
