1.Engineered with an innovative hollow and patented butterfly curve design, this ergonomic pillow mimics human anatomy to naturally align your spine and reduce cervical stress. The unique curve molds to your head's shape, providing ample shoulder space without feeling cramped. An extended armrest area allows for hand positioning, ensuring a painless slumber every night. 2.Our cervical pillow is designed to accommodate all sleeping positions. Simply flip it 180 degrees to switch between two curve heights (3.5' 3.1'). The profile suits larger frames and side sleepers, while the low profile is for front, back, and other sleeper types. Sculptable and adjustable, it provides support in any position. 3.Say goodbye to sweaty nights! The pillow features cooling technology with a temperatureneutral outer cover that never feels too cool or warm. Treated with plantbased MoveCool technology, it maximizes natural wicking, heat dissipation, and evaporation. The memory foam inner fill has a 95% permeable cell rate, enabling twice the airflow of conventional foams. This isn't just a cooling pillow—it's a complete thermal regulation system for unmatched comfort, all night long. 4.Constructed from quality memory foam, this pillow molds to the contours of your head and neck, offering customized support that adjusts to your body's needs as you change positions throughout the night.
