Down and feather pillows are wonderfully fluffy and comfortable, but they tend to lose their feathers often. It is a pain to pick up feathers from the floor that have escaped from your pillows. Furthermore, the more feathers that fall out of the pillow mean fewer feathers in the pillow to rest your head upon. But there are measures you can take to keep feathers in your pillows.
Remove the pillow case from the feather pillow.
Find the tag inside the pillow case and determine what the thread count of the fabric is. The higher the thread count, the less likely the feathers are to poke out. If you cannot find the thread count on the tag, take the old pillow case with you when you purchase a new one.
Purchase a pillow case that is of a higher thread count than the pillow case you have been using. A higher thread count pillow case is going to be more expensive, but it will be worth it in the long run. If you have brought the old pillow case along for reference, compare the appearance of the thread count and select the pillow case that looks the most dense compared to the old one.
Put the higher thread count pillow case on the pillow and enjoy.
If you need to wash your pillow, wash it in the highest thread count pillow case. Tie the end of the pillow case closed with an elastic hair tie to prevent feathers from escaping in the wash. It is also a good idea to wash your feather pillow in a front loading washing machine, rather than a top loading model.
