Why Replace the Pillow Back?

The pillow back mount is essential for keeping your spa headrest properly positioned. Over time, it can wear out due to exposure to:

• Heat and moisture
• Chemical exposure (chlorine/bromine)
• Frequent use and removal

Replacing the back mount ensures your pillow stays secure, comfortable, and properly aligned.

• Align the new mount with the spa shell receptacle
