This cushion offers a versatile "one cushion, multiple uses" system. It can be used as lumbar and back support, and it also supports prone sleeping. For those who prefer to lie in bed reading or browsing messages, this cushion provides soft yet firm support for the chest and abdomen, preventing breathing difficulties or muscle soreness caused by direct pressure. It also provides stable support for the lumbar spine and back, reducing muscle tension while ensuring comfort in contact areas. The high-quality material selection not only ensures the cushion's performance but also demonstrates the product's commitment to user health. This pillow exhibits excellent slow rebound properties-when subjected to external pressure, it slowly deforms to conform to the contours of the pressure area. Once the pressure is removed, it gradually returns to its original shape, ensuring long-term stable performance. Color: Dark Grey.
