Freedom Plush Budget Waterbed Mattress Insert
A Simple, Affordable Way To Leave Water Behind

The Freedom Plush Budget Waterbed Mattress Insert is designed for waterbed owners who want to eliminate water, heaters, leaks, and ongoing maintenance without replacing their existing hard-side wood waterbed frame. It fits directly inside the frame and installs on your current waterbed decking with no box spring required, allowing you to keep your headboard, drawers, and overall bed setup intact.
This model is intentionally built as a basic, entry-level solution for customers working within a tight budget who want a straightforward transition away from a traditional water mattress.

Freedom Plush Feel & Firmness
Firmness Rating: 7–7.5
The Freedom Plush Budget Waterbed Insert Mattress offers basic medium-firm support with a gentle, soft, one-sided plush surface, designed to make the transition from a waterbed to a traditional mattress feel more natural and forgiving.
This balanced feel provides enough firmness for support while maintaining a slight surface softness that many waterbed sleepers are accustomed to, making it an approachable, budget-friendly option for first-time waterbed replacement buyers.
Understanding Mattress Firmness
A Quick 1–10 Scale Guide
Water Mattresses
• 1 – Ultra-Soft: A floating, gently bobbing feel — our softest, most cloud-like water experience
• 4 – Firm: Maximum water support with reduced motion — our firmest water mattress option
Coil Spring Mattresses
• 5 – Firm: The starting point for coil mattresses; firmer than even our firmest water mattress, yet still offering a gentle surface feel with solid core support — ideal for transitioning from waterbeds
• 10 – Ultra-Firm: Maximum support with no sink; our hardest mattress option
At 7–7.5, the Freedom Plush sits above the initial transition range, providing a more stable, grounded feel while still maintaining surface comfort.
What To Expect From The Freedom Plush
The Freedom Plush is a one-sided mattress, designed for simplicity and ease of use. Because it does not flip, it requires less routine maintenance than two-sided mattresses, making it a convenient option for customers who want a straightforward, “set it and forget it” solution.
That said, the Freedom Plush does not include the heavier materials, reinforced construction, or extended lifespan found in our premium two-sided waterbed inserts. It is best viewed as a value-focused option, not a long-term heavy-duty mattress.
Who The Freedom Plush Is Best For
✔ Customers on a strict budget
✔ Guest rooms or occasional-use beds
✔ Lighter to average-weight sleepers
✔ Waterbed owners transitioning to a traditional mattress for the first time
Who Should Consider An Upgrade Instead
Due to its lighter, one-sided construction, the Freedom Plush is not recommended for plus-size sleepers, individuals with higher weight ranges, or customers seeking maximum durability and longevity.
If you’re looking for:
• A two-sided, flippable design
• Greater material depth and support
• Longer usable lifespan
• Improved performance for higher weights
We strongly recommend upgrading to the Prairie Dunes Plush Waterbed Mattress Insert.
