Using a bolster pillow under the knees can facilitate this alignment by promoting a neutral spine position.

The height of the pillow can vary depending on individual body size and mattress thickness, but a general recommendation is to use a pillow that is 4 to 6 inches in diameter. Additionally, the firmness of the pillow should provide adequate support without being too rigid, allowing for comfort during sleep.
This positioning has significant impacts on sleep quality and pain management.
