Unlike standard pillows that absorb water like a sponge—becoming heavy and sagging—our upgraded Polyurethane (PU) pillows feature a specialized "self-skinning" surface. This keeps the pillows light, soft, and ergonomically supportive. The non-absorbent material is easy to wipe clean with mild soap and water, ensuring a refreshed spa experience through every season. Protect Your Investment Rust is the enemy of a pristine spa shell. Our pillows utilize a 100% plastic integrated pin system. By eliminating all metal components, we ensure your spa remains free from rust streaks and staining. The "pop-in" design makes installation and removal for routine maintenance completely effortless—no tools required. Technical Specifications: Material: Premium High-Density, Non-Absorbent PU Foam.
