10 Best Side Sleeper Pillows 2025 in the United States

The Coop Home Goods Original Crescent Adjustable Pillow is designed especially with side sleepers in mind, offering a unique crescent shape that naturally supports the neck and shoulders to promote proper spinal alignment. Its standout feature is the fully adjustable memory foam fill, allowing you to add or remove foam to get your ideal pillow height and firmness—this is great if you like to customize your comfort or if your preferences change with seasons. The medium-firm feel suits many side and back sleepers, providing enough support without being too hard. The pillow uses a fresh blend of cross-cut memory foam and microfiber that balances softness and support, and its cover is made from breathable Lulltra fabric, helping with air flow to keep you cooler through the night. It’s also machine washable, which makes maintenance easier.

The foam can come with a mild new-product smell at first, which some people might find off-putting, though it fades with airing out. Also, to get the best loft, you’ll need to fluff or tumble dry the pillow before use, which is an extra step some might find inconvenient. The pillow’s size fits a queen bed comfortably, and its certifications ensure it’s free from harmful chemicals. For side sleepers seeking a pillow that provides personalized support and comfort through adjustability, this pillow presents a practical and thoughtful design, although those sensitive to initial odors or who prefer a simpler, non-adjustable pillow might want to consider other options.
