I bought this for back and shoulder blade pain. It's difficult because I can't reach those areas myself, right? It's a fairly firm, solid cushion. You place it on the floor and lie on it to stimulate the area. 【Unique Design】 This cushion has an X-shaped design that optimizes body support. It's specifically designed to correct the pelvis and posture. 【Comfortable Material】 It uses soft fabric, making it comfortable even for long periods of use. It's perfect for when you want to relax or for support while working. 【Versatile】 Suitable for use at home or in the office, and recommended for those who want to improve their posture. - Color: Pink and Gray - Shape: X-shaped - Material: Soft fabric - Purpose: Posture correction cushion Thank you for viewing.
