Pillow Insert - Coast Spas

OEM-specification replacement pillow insert foam core for Coast Spas hot tub headrests. Provides the padded inner structure inside pillow shell assemblies that have lost their cushioning over time. UV-resistant, chemical-safe foam construction withstands continuous spa water and chemical exposure. Designed for proper fit within compatible Coast Spas pillow shell assemblies. If your headrest pillow shell is in good condition but has gone flat, replacing the insert restores full comfort without replacing the entire pillow assembly. Verify your pillow model for dimensional compatibility.
