Foam Shoulders

Replacement Waterbed Foam Shoulders/ Foam Bolsters

The foam shoulders (also known as foam bolsters or foam perimeter borders) are the essential structural walls of any softside waterbed. Over years of daily use, original foam edges can sag or soften. Replacing worn foam shoulders restores a firm, comfortable sitting edge and keeps your water core held securely in place.

• High-Density Resilience: Specially engineered foam built to resist sagging and hold its shape under lateral water pressure.
• Precision Fit: Cut to fit standard UK and US softside waterbed sizes for both single, double, queen, and king dimensions.

Frequently Asked Questions

What do foam shoulders do on a softside waterbed?
Foam shoulders form the outer frame of a softside waterbed. They contain the water mattress, provide side support so you can get in and out of bed easily, and allow standard fitted sheets to fit neatly over the bed.

When should I upgrade my waterbed foam bolsters?
Replacing your foam shoulders helps restore firm edge support and keeps your softside waterbed looking perfectly tailored. Installing fresh bolsters ensures your mattress maintains its ideal rectangular structure, giving you a supportive new bed.
