This lumbar support cushion is precisely measured to fit the curve of your back during sleep, adapt to different sleeping postures, and maintain an "S" curve to reduce tossing and turning. The different thicknesses and stable triangular design keep your back and waist in good condition, support your back with few gaps, help you relieve stress at night, prevent lumbar muscle strain, and ease lumbar pressure. 4. High - grade memory foam: The internal filling material is medical - grade memory foam, which can maintain its shape to provide continuous support and is less likely to flatten.
