Overview
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. It sits at a firmness level that's firm enough to keep your lower back from sinking but cushioned enough that you're not lying on a board. The coil system does its job quietly, isolating movement so one restless sleeper doesn't wreck the other's night. Come in to any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option in its class so you can feel the difference yourself.
COMFORT AND FEEL: Luxury firm feel with quilted cushion on top and steady, lift-back coil support underneath.
SIZE: This queen sized mattress is a versatile 60" x 80" surface, well suited for couples or single sleepers who want room to move.
BEST SLEEP MATCH: Built for back sleepers and some side sleepers who want a luxury firm innerspring. The coils push back evenly, keeping hips and shoulders from dropping out of alignment overnight.
BEST FOR: Ideal for sleepers who need consistent lumbar support, want to minimize partner disturbance, or have been waking up stiff from a mattress that has lost its shape.
CONSTRUCTION SPECIFICATIONS: The stretch-knit cover moves with you and never pulls tight. A 1.5" super soft quilt foam layer takes the edge off the firmness at first contact. Below that, 1.5" of medium firm high-density comfort foam keeps the feel consistent night after night. An 8" 790-count pocketed coil system handles support and motion separation. A shock-absorbing high-density base foam anchors the whole build.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Compatible with adjustable bases, platform frames, and traditional box springs. No tools needed for setup.
NOT A FIT FOR: Sleepers who prefer a plush or pressure-hugging feel will find this too firm. Not recommended for those who need deep contouring at the shoulder.
