The different thicknesses and stable triangular design keep your back and waist healthy, fully support your back with little gap, help you relieve stress at night, prevent lumbar muscle strain, and alleviate lumbar pressure. D. Memory foam filling: The internal filling material is medical - grade memory foam, which can maintain its shape to provide continuous support and is less likely to flatten.
