10 Best Side Sleeping Pillow For Arm 2025 in the United States

The Sidney Sleep Pillow for Side and Back Sleepers is designed to offer customizable comfort specifically for those who sleep on their sides or backs. One of its standout features is the adjustable shredded memory foam filling, allowing users to add or remove foam to achieve their desired pillow firmness and height. This flexibility can be particularly beneficial for side sleepers who need specific support to reduce neck and shoulder pain.

The pillow comes in a queen size (19” x 29”) and includes extra foam filling, providing ample material to personalize your sleep experience. Its semicircular shape adds to its ergonomic benefits, designed to contour and hug your neck and shoulders comfortably. The breathable fabric made of polyester and viscose rayon adds to the comfort, ensuring you stay cool throughout the night. The hypoallergenic properties are also a plus for those with sensitivities.

However, while the pillow offers medium firmness out of the box, it may require regular upkeep such as fluffing daily and occasional drying to maintain the distribution of the memory foam. Additionally, the pillow is machine-washable, making it easy to clean, although some may find the maintenance a bit cumbersome. This pillow could be a good investment for side sleepers who value customizable support and easy maintenance.

The unique armrest design prevents arm numbness, making it comfortable for stomach sleepers as well.

Additionally, the pillow has an ear hole to reduce pressure on the ears, enhancing comfort and reducing the need to toss and turn during the night. The memory foam used is CertiPUR-US certified, ensuring it is safe, odorless, and can gradually adjust to the shape of your head and neck, providing sturdy support.

On the downside, some users might find the pillow's firmness and size not adjustable enough for their preferences, although the company offers a booster pad if the height is insufficient. This pillow is a reliable option for those looking for ergonomic and orthopedic support. However, it might not suit everyone due to its specific contour design and firmness level.

Some users might also find the pillow too firm or too soft depending on personal preference, despite its 'soft' firmness description. Weighing in at 5.34 pounds, it is relatively heavy for a pillow, which might be a consideration for those who move their pillows frequently. For side sleepers seeking targeted support with a focus on cooling and comfort, the Side Cube Deluxe offers a well-thought-out option, though it might not be as versatile for stomach or back sleepers.
