Serta Perfect Sleeper Nurture Night 12" King Review: Worth It in 2026?
Sep 28, 2026
In this serta perfect sleeper nurture night 12" king review, the short answer is that Serta's firm hybrid earns its number five ranking in our 2026 king size mattress guide, where we label it the best firm pick for back sleepers. The Serta Perfect Sleeper Nurture Night 12-inch King costs $1,200 and holds a 4.3-star average from 81 Amazon ratings, a thin sample that still points the right way. Its footprint is 79.5 inches long, 76 inches wide and 12 inches thick, so it fits standard king frames and sheets without drama. At 95.1 pounds, it is heavy enough that two people should handle the setup. Back sleepers who want a flat, supportive surface are the target buyer here.
Eight layers sit between the polyester cover and the pocketed coil core, and each one changes how the bed feels at night. For example, the 825-coil system contours under the shoulders and hips while keeping motion transfer low, so a partner who shifts at 2 a.m. is less likely to wake you. On top of that, a gel memory foam band runs across the lumbar zone, which adds push at the lower back where softer mattresses tend to sag. The Cool Twist gel memory foam swirls cooling gel into the foam to move heat away rather than trap it, and a 1-inch PillowSoft Aire layer softens the surface without turning it plush. Even so, the tight top and firm feel stay consistent from edge to edge thanks to the edge support. CertiPUR-US certification covers the foam.
At $1,200, the Nurture Night sits in the middle of our king mattress guide, above budget hybrids and below the premium picks. By contrast, shoppers who mainly need pressure relief at the shoulders will get more from a softer bed, since a firm surface can create pressure points for side sleepers. The honest caveat is evidence: 81 ratings is a small base for a $1,200 purchase, so read the recent reviews before you commit. That said, the 100-night trial and 10-year limited warranty lower the risk, and CertiPUR-US certification plus a US-made build with global components back the brand promise. Which means back and stomach sleepers who want lumbar support from a familiar name can buy with reasonable confidence. If you sleep on your back and wake up with a stiff lower back, this is the one to get.
