R2C Dream Gentle Firm Waterbed Mattress Insert
Prefer A Firmer, More Supportive Sleep — Without Replacing Your Bed?
The R2C Dream Gentle Firm Waterbed Mattress Insert is designed for customers who want to move away from a traditional water mattress without giving up the hard-side wood waterbed furniture they already own — and who prefer a noticeably firmer, more supportive sleep surface.
Rather than removing your frame and starting over, the Dream Gentle Firm allows you to keep what already works: your wood frame, headboard, pedestal drawers, and bedding. The mattress installs directly on your existing waterbed decking, requires no box spring or foundation, and permanently eliminates water, heaters, hoses, conditioners, and ongoing maintenance.
- No water.
- No motion.
- No upkeep.
- Just solid, dependable support.
Purpose-Built Fit For Hard-Side Waterbed Frames
Unlike standard mattresses sold in furniture stores, the Dream Gentle Firm is engineered specifically to fit inside a hard-side waterbed cavity. It is intentionally sized slightly smaller than the frame in both width and length, providing space to tuck sheets, make the bed easily, and avoid the tight, forced fit that often causes frustration with ordinary mattresses.
The result is a cleaner look, easier daily use, and a mattress that fits your furniture the way a waterbed insert should — because it was designed for it.
Firm Support, Controlled Comfort
At the core of the Dream Gentle Firm is an 8″ heavy-gauge, individually encased coil system, delivering strong, consistent support across the entire sleep surface. Above the coils, carefully selected foam layers provide light cushioning while maintaining a firm, stable feel that resists sink and promotes proper spinal alignment.
This construction replaces water motion with true mechanical support, offering greater stability, improved posture support, and a more grounded sleep experience, especially appealing to sleepers who find plush mattresses too soft or unstable. Because the mattress is two-sided, you can flip and rotate it regularly to promote even wear and extend the comfort life well beyond typical one-sided mattresses.
