It’s always frustrating when your soft, fluffy pillow gets flat and lumpy overnight. But it’s not just an annoyance — it can be a (literal) pain to wake up with your head on a sagging pillow. That’s why it’s vital to find the best pillows that don’t go flat, so you can ensure your spine is always in proper alignment while you sleep. These pillows will be made from materials that offer plenty of support, like natural latex foam or hyper-elastic polymer, and some offer bonus qualities like temperature-regulation and machine-washability.

The filling is the chief consideration to keep in mind when you’re searching for a pillow that will retain its shape overnight. Many traditional fillings like down and feather tend to lose their shape, get lumpy, and flatten, but newer foam materials and pillow constructions have changed the sleep game.

  • Memory foam, a material commonly used for mattresses, conforms to your head and neck while still providing support — and now you can even find memory foam pillows with adjustable fillings to get the right amount of fluff, firmness, and shape for you. Keep in mind, however, that memory foam tends to absorb body heat, so it’s not the best choice if you’re a hot sleeper.
  • Latex foam, which is derived from the rubber tree, doesn’t feel as fluffy as real or alternative down, but its firm bounciness makes it a fantastic option that shouldn’t sag with use.
  • If you sleep hot, you might consider a pillow made with innovative hyper-elastic polymer materials that are designed to hold their shape and help you stay cool at night.
  • Finally, while not always the most durable, fluffy fiber-filled pillows can be a solid choice for anyone on a tight budget, because they are easy to re-fluff in the dryer when they start to show signs of flattening.

From a springy foam pillow with adjustable height options to a polyester option that’s a fantastic wallet-conscious option, here are four of the best pillows that won’t go flat while you catch up on some zzz’s.


Editor’s Choice: The Best Adjustable Shredded Memory Foam Pillow

With more than 48,000 reviews on Amazon thus far and a five-year warranty, the Coop Home Goods adjustable loft pillow is a fantastic pick. I have this pillow myself, and it makes every night so much more comfortable than other pillows I’ve tried. It’s pricier than some pillows, but in my opinion, it’s well worth the cost.

Filled with a medium-firm combination of memory foam and microfiber, the Coop Home Goods pillow is actually loft-adjustable — simply add or remove the memory foam fill until you get to your desired height and firmness. In fact, the pillow comes with a 1/2-pound bag of extra fill so that you can add some for extra support that won’t go flat. (That being said, I’ve been using mine for almost a year and it has yet to feel flat — but even if it did, I could just add more of the fill I saved when I first unboxed it.) Made from polyester and bamboo-derived rayon, the soft cover is removable, washable, and hypoallergenic.

The pillow is made in U.S., and in addition to the warranty, it comes with both a 100-night refund policy so that you can get your money back right away if you decide it’s not for you. The pillow is CertiPUR-US and GREENGUARD Gold-certified, so you know it’s safe and free of toxic chemicals. Besides this queen version, the pillow is also available in king size. Neither size of pillow comes in pairs, so if you want a matching set for your bed, you’ll simply have to buy two.

Positive Amazon review: “Absolutely the BEST investment I’ve ever made. Super soft and supportive. This is how I always imagined how a big puffy cloud in the sky would feel. I could go on and on it’s more than I’d hoped for.”


The Best Latex Foam Pillow That Keeps Its Shape

This natural latex foam pillow offers a bit more bounce-back than memory foam, so it’s almost guaranteed not to go flat during the night. For eco-friendly peace of mind, the latex is derived from renewable and sustainable hevea trees, and it’s OEKO-TEX-certified to be free of petroleum and volatile organic compounds. Plus, it’s especially durable as far as bedding materials go, so you won’t be looking at a reinvestment any time soon. In addition to keeping its shape, this pillow also has anti-allergy properties, and the open-cell structure enhances breathability — helpful for anyone who sleeps hot. The 400-thread count cotton sateen cover is removable and machine-washable, but the latex foam itself must be spot cleaned, according to one reviewer. The biggest drawback: This pillow is only available in a queen-sized version.

Positive Amazon review: “This latex pillow is amazing. It has a softness but bounce which helps keep my head from sinking into the pillow. Highly recommend.”


The Best Budget Pillows That Are Super Fluffy

For a fraction of the cost of the other pillows on this list, you can get two Bedsure pillows. Inside each pillow you’ll find a polyester fiber filling that offers softness and fluffiness, and the reinforced seams provide excellent durability. Unlike the other pillows on this list, these pillows are totally machine-washable, plus you can pop them in the dryer to fluff them up from time to time.

These pillows likely won’t last quite as long as the pricier options, but many reviewers have reported they offer plenty of comfort and longevity, making them a good choice if you’re sticking to a budget. One reviewer described them as “more comfortable than hotel pillows!” and another wrote that they’re “like sleeping on fluffy clouds.” Be advised that you may have to fluff them more frequently, as they offer less firm support or bounce-back, but at this price point, it’s a fair tradeoff. While these pillows come in soft and firm versions, shoppers have noted that even the firm pillow is on the soft side. In addition to queen size, they also come in standard and king sizes.

Positive Amazon review: “My husband and I love the softness and comfort of these pillows. You can shape them as best fits your needsyet they can be fluffed back to their original shape. They are more for softness than strong support. We also like the fact that they are hypoallergenic.”


The Best Temperature-Regulating Pillow With Adjustable Bolsters

Although it’s a pricy option, this Purple pillow may be worth the investment if you’re a hot sleeper. The unique pillow is made of a supportive hyper-elastic polymer and designed with a breathable grid structure and temperature-neutral gel to keep your body cool all night long. The moisture-wicking pillow is stretchy for a tight fit, and made from a machine-washable blend of polyester, nylon, and spandex.

Perhaps the biggest selling point: The pillow comes with mix-and-match boosters, so you can adjust the height between 1, 2, and 3 inches for customizable support. Reviewers have confirmed that the pillow retains its shape overnight and offers some bounce-back, similar to a latex pillow.

Positive Amazon review: “Really happy with this pillow. I like thinner pillows, so I use it without the optional height-adder things. Works perfectly for all sleeping positions (I usually lie on my back, then my side). It stays very cool throughout the night, has a very satisfying springy-ness to it, and is just super comfortable. [...] What more could you ask for in a pillow? Comfy as heck and cool weird material.”
