About the Sleeptronic Oracle Plush California King Mattress with Low Profile Box Spring

The Sleeptronic Oracle is a 12-inch plush memory foam mattress with a tight top, sold as a California King set with a 5-inch low-profile box spring. The soft memory foam surface suits side sleepers and people who want a deep, cushioning feel rather than a firm, bouncy one. It is adjustable-base compatible, so it works with a powered frame for head and foot elevation. Against innerspring and hybrid rivals it trades bounce and edge support for pressure relief and motion isolation, and the low-profile base keeps the whole setup lower than a standard box spring.

    Questions and answers

    Is the Oracle Plush good for side sleepers?
    Yes. The plush memory foam cushions the shoulders and hips, which is where side sleepers carry pressure. Back sleepers may find it supportive enough, but stomach sleepers usually want something firmer.
    Does it work with an adjustable base?
    Yes. Sleeptronic lists the Oracle as adjustable-base compatible, so it can be used on a powered frame that raises the head and feet. The included low-profile box spring is for a standard bed frame, not an adjustable base.
    How firm is the Oracle Plush?
    It is a plush mattress, the softest comfort level in the line. Expect a deep, sinking feel rather than a firm surface, so heavier sleepers and stomach sleepers may want a firmer model.
    What is included with this California King set?
    The set pairs the 12-inch Oracle Plush mattress with a 5-inch low-profile box spring. The mattress is a tight-top memory foam build with no removable cover.
    Will the mattress sleep hot?
    Memory foam tends to trap heat more than latex or coil hybrids. A breathable mattress protector and a cooler room help, but hot sleepers may prefer a hybrid design.
    How does it compare with a hybrid mattress?
    The Oracle isolates motion and relieves pressure well, but it has less bounce and weaker edge support than a coil hybrid. Choose it for a soft, quiet feel; choose a hybrid for responsiveness and cooler sleep.
