Nobody warned you about this part of caregiving. The cushion that went flat in a week. The red mark on Mom's tailbone you find too late. The closet full of "bestsellers" that failed her β while you kept blaming yourself. You're not imagining it. And you're not alone. 95% of pressure sores are preventable β but foam cushions compress, bottom out, and trick you into thinking the pressure is gone when it's just hidden. You've been fighting the right battle with the wrong weapon.
