Mancini's Sleepworld Diamond Luxury Firm Mattress 11.5" · Queen

⭐⭐⭐⭐ 4.4 · 100+ verified sleepers

The Mancini's Sleepworld Diamond Luxury Firm Mattress 11.5" is an innerspring mattress built for back sleepers and combination sleepers who want real spinal support without giving up surface comfort. This is the mattress for the person who has tried plush options and woke up sore, but found a traditional firm too unforgiving at the hips. The Diamond Luxury Firm threads that needle with a quilted knit comfort layer that takes the edge off, and a pocketed coil system that handles the real structural work underneath. If you want to feel what this mattress does for your body before you commit, our sleep specialists at any Mancini's Sleepworld location will lay it next to every competing option in the store so you can decide with confidence.

COMFORT AND FEEL: Luxury firm feel with gentle quilted cushioning and firm, uplift-focused support beneath.

SIZE: This queen sized mattress is a smart fit for couples or solo sleepers who want full freedom of movement at night.

BEST SLEEP MATCH: Back sleepers and some side sleepers do best here. The luxury firm feel keeps the lumbar lifted and supported without locking the hips in place. A solid match for the firm mattress for back pain relief seeker who still wants a cushioned surface.

BEST FOR: Ideal for sleepers who need consistent spinal alignment, prefer a firmer feel without a hard surface, or share a bed and want less motion disturbance.

CONSTRUCTION SPECIFICATIONS: The stretch knit cover moves with you and softens the first point of contact. Beneath it, a layer of super soft quilt foam takes the initial edge off firmness. Medium firm high-density comfort foam then handles pressure at the hips and shoulders. The 8-inch 790 pocketed coil system responds individually so movement on one side stays there. A shock-absorbing high-density base foam anchors the whole system and resists softening over time. Foams are CertiPUR-US® certified.

SETUP AND COMPATIBILITY: Delivered flat with professional in-home setup included. Compatible with adjustable bases, platform frames, and standard box springs. No tools needed on your end.

NOT A FIT FOR: Sleepers who prefer a plush or pressure-cradling feel may find this surface too firm. Not recommended for strict stomach sleepers who need a very flat, ultra-firm profile.
