Mancini's Sleepworld Harbor Hybrid Luxury Firm Mattress 10"

The Mancini's Sleepworld Harbor Hybrid Luxury Firm Mattress 10" is a hybrid mattress built for back sleepers and combination sleepers who need firm, reliable support without losing the body-conforming cushion that takes pressure off the hips and lumbar. HD gel-infused memory foam sits beneath the breathable stretch-knit cover, drawing heat away before it can build up, while 840 pocketed coils respond zone by zone underneath.

Why this Mattress?

• Built for the back sleeper who runs warm and wakes up stiff
• Gel-infused memory foam draws heat away from the body
• 840 pocketed coils respond independently for targeted support
• Breathable stretch-knit cover keeps surface cool and soft
• Firm enough to lift the lumbar, gentle enough for side relief

Comfort and feel: Luxury firm with a cool, contouring surface and steady lumbar support beneath.

Best sleep match: Back sleepers and lighter-framed side sleepers. The gel foam cushions pressure at the hips while the coil system keeps the spine level.

Best for: Sleepers who run warm, need consistent lumbar support through the night, or wake up stiff in the lower back.

Construction: 8" 840 pocketed coil system, 1.5" HD gel-infused memory foam, and a transition foam layer between the two. CertiPUR-US® certified foams.

Setup and compatibility: Works with adjustable bases, platform frames and box springs. Arrives rolled and compressed.

Not a fit for: Sleepers who prefer a plush or pillow-top feel, or strict side sleepers with significant hip-to-waist difference.
