For those concerned about posture or lower back pain, I am selling a Pint posture support cushion (light gray). I used it at home for about six months. The urethane foam inside shows signs of use, but it functions perfectly fine when used with the cover, and I think it can still be used for a long time (*^^*) (Please refer to the photos for the condition and size of the product.) If you want to change the look or have a spare cover, you can purchase a separate cover from an online shop. Please consider this item, understanding that it is used.
