9252 Semi-Waveless Hardside Waterbed Bladder — Parkline 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 and looks like a conventional mattress — 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
*Hardside frame, heater, fill & drain kit, and conditioner sold separately.

So far, so good
Not much. I'm still sleeping on the couch for several unrelated reasons. Customer Service from Sterling was wonderful. It was more than 20 years ago when I bought the last one, it lasted for more than 20 years, and they were still happy to have a repeat customer. If they and I are still around 20 years hence, would very much shop there again.
California King size water mattress
This mattress is great & I really like it. Although I ordered a waterbed the same as this one about 8 years ago and when it sprung a leak now I was very disappointed as I have only had one other mattress over the past 30 years which lasted 30 years, not 8.
