Bath pillows, like adult pillows and baby pillows, are made of polyester breathable mesh. When you're dragging yourself home from work, taking a warm bath in the tub is a great way to relax. A bath pillow is a great way to help you lean back in the tub and enjoy yourself. The back of the pillow has suction cups to help it stay attached to the wall of the tub and not slide easily. Mesh fabrics are very breathable and easily permeable to water. After use can be quickly hung to dry, not easy to breed bacteria.
