The pillow features four removable foam layers that can be mixed and matched to create eleven height options, ranging from 1.2 in. to 6.1 in. This design supports different sleeping positions, including side, back, and stomach sleepers, by allowing users to tailor neck height and firmness. The product uses three foam materials: ultra-soft white contour memory foam, soft blue memory foam, and a firm white foam, with the option to use layers individually as flat pillows for stomach sleepers. The system aims to promote proper spine alignment and reduce neck and upper back discomfort by providing targeted support where needed. The memory foam is CertiPUR-US certified for safety and durability, and the pillow is designed to retain its shape over time. A removable, machine-washable cover provides easy cleaning; the cover is made from a breathable blend of 60% polyester and 40% rayon derived from bamboo, with ventilation holes to help dissipate heat. Height adjustments simply involve adding or removing flat layers, making maintenance straightforward. The design also emphasizes simple care without introducing new clutter in the bedroom. Overall, the pillow offers a flexible shaping process that can adapt to evolving preferences and sleep environments while maintaining airflow and comfort. Color: Black.
