Our Editor’s Pick, the Helix Pillow, has a removable support insert layer so you can adjust the height and firmness for the perfect fit. It’s made with a breathable, 100 percent cotton cover and gel microfiber fill to keep you from overheating at night.
Reason to Buy: With the Helix Adjustable Pillow, side sleepers don’t have to choose between a plush or firm pillow—they can simply adjust the feel to their liking. That being said, Helix recommends the firm option if you sleep on your side, as reducing the loft too much could throw the spine out of alignment and create shoulder pressure. The Helix brand is also known for some of the best customizable mattresses.
The microfiber fill offers the same plush, luxurious feel of a down pillow but is hypoallergenic, so it won’t trigger allergies. The pillow’s gel-infusion properties, combined with the cotton cover, will dissipate heat for people who sleep hot. To boot, the Helix has an easy-to-clean machine washable cover. It also comes with a 100-night sleep trial, free shipping, and a one-year warranty. The Helix is available in Standard and King sizes for under $100.
