Pillow Cube : Side Cube Riser

The Adjustable Pillow for Side Sleepers Most side sleeper pillows force you to adapt to their shape. The Side Cube Riser adapts to yours. Engineered specifically to fill the 90-degree gap between your shoulder and head, this patent-pending modular pillow delivers perfect neck and spine alignment without the guesswork of standard sizing. How the Modular Height Works Finding the right pillow height is critical to preventing neck pain. The Side Cube Riser ships fully stacked at 5 inches—the ideal height for most side sleepers right out of the box. If 5 inches feels too tall, you are in complete control. Unzip the cover and remove one or both of the included 1-inch foam risers to drop the pillow down to a 4-inch or 3-inch profile. You get one pillow with three precise height options, ensuring a perfectly personalized fit for your shoulder width. Key Benefits & Features Targeted Pressure Relief: The purpose-built cube shape stops your head from tilting downward, cradling your head while reducing strain on your neck and shoulders. AeroFoam Core: Premium viscoelastic polyurethane foam provides consistent, responsive support while actively resisting overnight heat buildup. Cooling Ventilated Cover: The soft, breathable outer shell pulls heat away from your face and neck. It is completely removable and machine washable for easy hygiene.
