9876 Super Waveless Waterbed Mattress- Edge Support, Back Support, Hardside bladder

9876 Super Waveless Hardside Waterbed Mattress — Original Series

What is a Hardside Waterbed? A hardside waterbed uses a rigid wooden frame that the water bladder sits inside directly. It has the classic, traditional waterbed look and feel. Unlike a softside waterbed — which fits inside any standard bed frame — a hardside requires a dedicated waterbed frame.

This listing is for the bladder only. Hardside cover systems are available separately and can enhance comfort and protect your bladder — but they are not required for use with a hardside waterbed frame.

Hardside vs. Softside — What’s the Difference?

• Hardside (this product): Bladder sits inside a dedicated wooden waterbed frame, traditional look, classic wave feel
• Softside: Foam-encased, fits any standard bed frame, looks like a regular mattress, easier to move
