Do bath pillow suction cups actually stay stuck to the tub?

Grip is the single most common complaint across verified-purchase reviewers in this category, and it depends heavily on your tub surface. Smooth acrylic and enameled tubs hold suction cups best; textured, matte, or stone-resin surfaces let pillows slide. Models advertising six or seven strong cups (such as the AmazeFan and RUVINCE picks) get more consistent grip feedback, but reviewers across nearly every product note that cups need a clean, wet, smooth surface to hold.
