Why do pillows go flat? The truth revealed!

There’s nothing like the comfort of a soft, plump, and fluffy pillow when you’re trying to catch some zzz’s. However, over time, you may notice that your pillow is getting flatter and losing its shape. Have you ever wondered why your pillows go flat? There are several reasons why pillows flatten out, such as age, usage, and material quality. In this article, we’ll explore the various reasons behind the phenomenon and offer some tips on how to prevent it from happening too soon.

Age Matters

Age is inevitable, and it affects everything – including your pillows. Pillows that have been in use for a long time tend to lose their shape and become flattened. Over time, the fibers inside the pillow break down and become compressed, making your once fluffy pillow look and feel flat. If your pillow has been with you for many years, it may be time to consider replacing it with a new one.


Replace your pillows every 18-24 months to avoid the flattening effects of age. Make sure to invest in high-quality pillows that are made from durable materials that can withstand continuous usage and frequent washes.

Usage and Maintenance

How you use and care for your pillows are other factors that can contribute to their flattening. When you rest your head on your pillow every night, you’re applying pressure on the fibers inside the pillow, which can lead to compression and flattening over time.

Additionally, not washing your pillows regularly can also cause them to go flat. When you don’t wash your pillows, sweat, oil, and dead skin cells build up inside them, making them heavier and more susceptible to losing their shape.


  • Change your pillowcases weekly and wash them in hot water to kill bacteria and germs.
  • Wash your pillows every three to six months, depending on how much you sweat at night. Follow the manufacturer’s instructions for washing and drying.
  • Fluff your pillows daily to redistribute the fill and help them retain their shape.

Fill Material Quality

The quality of the fill material in your pillow can also play a role in how long it retains its shape. Some materials, such as down and feathers, are more likely to compress and flatten over time than synthetic alternatives like memory foam and polyester.


Invest in high-quality pillows that are made from materials that are known to retain their shape for longer periods. Memory foam and polyester are two great options that are more likely to hold their shape and last longer than down or feather pillows.

Pillow Care Tips

While it may seem like a hassle to keep your pillows in good shape, taking the time to properly care for them will ensure that they stay fluffy and comfortable for longer periods. Here are some additional tips for keeping your pillows in top shape:

  • Avoid folding your pillows or sitting on them, as this can contribute to flattening.
  • Fluff your pillows daily to keep the fill from becoming compressed.
  • Choose pillows with removable covers for easy washing and maintenance.
  • Store your pillows in a cool, dry place to prevent mold and mildew.


Pillows are an essential part of getting a good night’s sleep. However, over time, they can flatten and lose their shape, making them uncomfortable and less supportive. By understanding the reasons behind pillow flattening and taking proper care of your pillows, you can ensure that they stay fluffy and comfortable for as long as possible. Remember to invest in high-quality pillows, wash and fluff them regularly, and store them properly to prevent flattening and extend their lifespan.
