Made with shredded memory foam, this fan-favorite pillow is soft and can be adjusted to your preferences. Simply unzip the side and add or remove as much memory foam filling as you want to customize this pillow to your sleep style. With a 4.5-star rating on Amazon and over 1,300 reviewers weighing in, this is far and away one of the most comfortable pillows you can buy. The pillowcase is also made with 40 percent bamboo, so it'll keep you cool if you tend to overheat at night. But, even better, it comes with a 100-night trial, so you can test it out for yourself, and a five-year warranty after you decide to keep it. They're a bit pricier than other pillows on this list, but reviewers are quick to say they're worth it.

What fans say: "Worth every penny! I LOVE this pillow. My neck had been bothering me for a while. This pillow is so good because you can adjust the amount of filling to fit your size and shape. The cover is so soft! It does not go flat during the night. I am so thankful that I took a chance on this pillow. It has helped immensely!"
