Much like your mattress, your pillows are an important part of creating a solid foundation for a good night's rest. And finding one that works for you can mean the difference between a night of peaceful snoozing or an evening spent tossing and turning.
That being said, not all pillows are created equal, and what's right for one person might not be right for you (and as a result, you could spend more time laying awake at night). Plus, even if you do find one that you love, it's not meant to last forever. In fact, it should probably be replaced more often than you think.
So we turned to the experts to help break down everything you need to know about your pillows, from how to choose the right one to how to know when it's time to refresh yours.
How often do you need to replace your pillow?
The truth is, your pillow can get pretty gross. Things like dead skin cells, hair, dust mites and sweat can accumulate on your bedding and pillows, which isn't just disgusting to think about, but can actually exacerbate things like allergies and asthma.
Plus, over time the pillow will soften and compress. "A really good pillow will only last you about two or three years," says Rebecca Robbins, instructor in medicine at Harvard Medical School's Division of Sleep Medicine and co-author of the book "Sleep for Success!" "So, unfortunately, it is something that you have to refresh relatively regularly, but it doesn't have to break the bank."
Though, as previously reported by TODAY, using a protector can double the life of your pillow.
If you're not sure how long you've had your current pillow, one sure-fire way to know when it's time to look for a new one is if your pillow is causing pain or discomfort, either throughout the night or in the morning when you wake up, Robbins says.
How do I know which pillow is right for me?
Here's the thing: There's no such thing as a perfect one-size-fits-all pillow. "We're all different shapes and sizes, and we need different pillows and mattresses for that reason," Robbins says. "We also all have different preferences for softer surfaces or harder surfaces, which also ideally are factored into the equation."
That being said, the way you sleep could be helpful for determining which type of pillow you choose. While people tend to move throughout the night (yes, even if you think you sleep like a log, you probably still move around), we spend most of our time in one of three positions: on our back, stomach or side, Robbins says.
If you're a side sleeper, you're in good company. According to Robbins, about 60 percent of people sleep on their sides. The position is even said to open the airways and improve airflow as you sleep. But in order to support this sleeping style, you may need a pillow with a little more substance that will fill the gap between your head and shoulder. "The side sleeper needs the most voluminous of all pillows," Robbins says. "If you imagine lying on your side, your shoulder will somewhat get compressed into the mattress, but you're still supporting your brain and the space between your head on the pillow and your shoulder, and so that actually is quite a big space."
Back sleepers are the next most common group, Robbins says. People with sleep apnea, cardiac disease and acid reflux often sleep on their backs, and the position can help improve the alignment of your spine and neck.
For these kinds of sleepers, Robbins says ideal pillow is one that has a concave area in the middle and support at the neck.
Finally, a stomach sleeper needs the least amount of support, she says. So those who sleep in that position can get away with using a thin pillow or even just sleeping straight on the mattress.
Aside from that, other aspects of the pillow tend to be a matter of personal preference. "Some people really like the idea of down feathers, others really liked the idea of foam," Robbins says. "And whether you sleep hot or cold, it's not a huge consideration, when you're just talking about your shoulders and your head." That being said, she says she does recommend looking for hypoallergenic materials, especially if you have allergies.
How to clean your pillows
To help clear away some of that sweat, dirt and other debris so you can sleep more peacefully, cleaning coach Leslie Reichert previously shared with TODAY that you should be washing your pillows every three months.
Most of the time, you can find the cleaning instructions on the tag of your pillow. And while some can be thrown in the washing machine, others need to be hand-washed or can't be washed at all.
To start, with non-washable pillows, like most memory foam options, you should freshen them by vacuuming on a low-suction setting or placing them in the dryer on an “air only” setting for 15 to 20 minutes, Reichert said. If there are stains, you can spot-clean them using a cloth that's been lightly moistened with mild soap and water. After, she suggested rinsing with a damp cloth, blotting with a clean towel and letting air dry.
For pillows that are hand washable, she recommended submerging the pillow in a tub of lukewarm water mixed with some mild detergent. Carefully squeeze the pillow to circulate the water and clean it (foam, when wet, is fragile and can tear easily, she said, so be gentle). Once clean, rinse with cool water until it runs clear, squeeze to remove excess water and place on a flat surface to dry.

Plus, we also found a handful of top-rated pillow covers that will help you extend their life.
