Questions and answers

Is the Slumber Cushion Firm good for hot sleepers?
It is built for them: gel memory foam, a cooling gel infusion and moisture-wicking claims. Pocket coils also let air move through the core better than a solid foam block.
How firm is it really?
Sleepy's lists it as medium, and the Cushion Firm name suggests a soft-to-medium feel. Side sleepers usually like that; back sleepers who want a hard surface may not.
Does it work for couples?
Individually wrapped coils isolate movement, so a partner's turning is less likely to wake you. The reinforced edges also give you more usable surface.
What size is a California King?
It is 84 inches long and 76 inches wide, 4 inches narrower and 4 inches longer than a standard King. Check your frame and room before ordering.
Is the foam safe and low-odor?
The foam is CertiPUR-US certified, which limits certain emissions and heavy metals. A short airing-out period after unboxing is still normal.
Is $1,999.99 a good price?
It is the only new price found as of November 7, 2026, at Mattress Firm, so there is no recent range to judge it against. Compare it with other medium pocket-coil California Kings before buying.
Where is the Sleepy's Slumber Cushion Firm Mattress Cal King cheapest?
At Mattress Firm, for $1,999.99, as of our latest check.
