Mancini’s Sleepworld Harbor Hybrid Luxury Firm Mattress 10″ Queen
The Mancini’s Sleepworld Harbor Hybrid Luxury Firm Mattress 10″ is a hybrid mattress built for the back sleeper who runs warm and wakes up stiff. If you’ve been searching for a luxury firm hybrid mattress queen that delivers real lumbar lift without sacrificing surface softness, this is the mattress to feel. An 840 pocketed coil support system works beneath HD gel-infused memory foam to hold the spine in a neutral position from the first night forward. The coils move independently, so you stop feeling your partner shift at 2 a.m. If you’re unsure which firmness is right for you, come into any Mancini’s Sleepworld location and our sleep specialists will put this next to every comparable option so you can feel the difference for yourself.
COMFORT AND FEEL: Luxury firm with a cool, gently cushioned surface and firm spinal lift underneath.
SIZE: This queen sized mattress is ideal for solo back sleepers and couples who each need their own space without a king-sized footprint.
BEST SLEEP MATCH: Back sleepers and combination sleepers who prefer a firm mattress for back pain relief will find the pocketed coils hold the lumbar in place while the gel foam takes the edge off pressure points.
BEST FOR: Ideal for sleepers who run warm, wake up with lower back tension, or want coil responsiveness without the bounce of a traditional innerspring.
CONSTRUCTION SPECIFICATIONS: An 840 pocketed coil base moves independently to support each part of the body. A layer of HD gel-infused memory foam sits above the coils, pulling heat away and contouring to the hips and shoulders. A transition foam layer bridges the gap between coil response and surface feel. The breathable stretch-knit cover lets airflow reach every layer. Foam components are CertiPUR-US® certified.
SETUP AND COMPATIBILITY: Works with adjustable bases, platform frames, and box springs. Delivered flat with professional in-home setup included, no tools needed.
NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel. Side sleepers with significant hip and shoulder pressure needs may want a softer comfort level.
