Overview
Mancini's Sleepworld Diamond Extra Firm Mattress 11" · Queen
⭐⭐⭐⭐⭐ 4.6 · 100+ verified sleepers
The Mancini's Sleepworld Diamond Extra Firm Mattress 11" is a hybrid mattress built for back and stomach sleepers who need reliable, no-give support from the first night through the last. An extra firm mattress for back pain relief is exactly what this bed delivers: a flat, stable sleep surface that keeps the lumbar lifted so you stop waking up stiff. The coil system is wrapped in fabric to absorb motion independently, so one restless sleeper stays on their side of the bed. Stop by any Mancini's Sleepworld location and our sleep specialists will put this mattress next to every competing option so you can feel the difference for yourself.
COMFORT AND FEEL: Extra firm and flat, with zero sink and strong lumbar push-back throughout the night.
SIZE: This queen sized mattress is ideal for couples or solo sleepers who need full back support across a 60" x 80" surface.
BEST SLEEP MATCH: Best suited for stomach and back sleepers who need a firm mattress for back sleepers. The unyielding surface keeps the hips from dropping, which is exactly what those positions need to stay aligned.
BEST FOR: Ideal for sleepers who carry weight in the midsection, wake up with lower back stiffness, or need a mattress that simply will not soften out over time.
CONSTRUCTION SPECIFICATIONS: The stretch knit quilt panel flexes with movement while the firm foam layers beneath it keep the surface flat. A fabric-wrapped coil system built with super heavy-gauge wire holds firm under pressure without transferring motion. Super high-density upholstery-grade foam in the base resists compression and keeps this mattress feeling the same in year three as it did on day one. Foams are CertiPUR-US® certified.
SETUP AND COMPATIBILITY: Works with an adjustable base, platform frame, or box spring. Delivered flat with in-home professional setup included and no tools required.
NOT A FIT FOR: Side sleepers or anyone with hip and shoulder pressure sensitivity. This mattress is built to resist, not contour.
