The ER600’s distinguishing feature is its Progressive Rate Spring (US Patent #4905331). This system adjusts to your weight and position to cushion your pressure points and perfectly support your lumbar region, eliminating the dreaded droop that causes back pain. Sleep through the night without disturbing your partner on a mattress that’s never too soft or too firm.
Our patented edge support system maintains a slightly firmer border compared to the middle of your mattress, keeping you in your perfect sleep position all night.
The Progressive Rate Spring is a panted support system inside the ER600 Softside Waterbed Mattress. It responds to your weight and position for perfect comfort without disturbing your partner.
Back pain makes it hard to shop for a bed, but not at Sterling. The ER600 Softside Waterbed Mattress with back support eliminates back pain without sacrificing comfort.
Wave reduction is crucial to achieving a good night’s sleep. Our Super Waveless ER600 is an 8” water bladder with a wave-eliminating tether system to minimize any unwanted ocean motion.
