U-shaped pelvic and posture correction cushion made of breathable mesh material. Memory foam. - Color: Navy - Design: U-shaped design - Material: Mesh material - Purpose: Pelvic and posture correction - Features: Breathable, removable and washable cover Thank you for looking. I bought this as a pair for my husband, who has poor posture and a habit of sitting cross-legged. I've become conscious of my posture and feel corrected, and I really like it, but my husband says it feels constricting and doesn't use it. Would anyone like to have it? It's almost new.
