The Sleepworld Express 11" Innerspring Extra Firm Mattress is an extra firm mattress built for back and stomach sleepers who need a solid, unyielding surface that keeps the spine neutral all night. A heavyweight 4-way stretch knit quilt panel opens the sleep surface, with firm support foam underneath that cushions without compromising the feel underfoot. The coil system is wrapped in fabric and built with super heavy gauge wire, delivering the kind of resistance that prevents the gradual softening that extra firm sleepers dread. The high-density upholstery grade support layers underneath add lasting structure, so the mattress feels the same in year three as it did on delivery night. Stop by any Mancini's Sleepworld location and a sleep specialist will lay this beside every competing option so you can feel the difference for yourself.

COMFORT AND FEEL: Extra firm with a flat, stable surface and strong coil pushback under every position.

SIZE: This twin sized mattress is ideal for children's rooms, solo sleepers, and smaller spaces where firm support matters most.

BEST SLEEP MATCH: Back and stomach sleepers will get the most from this extra firm innerspring mattress for back pain relief. The coil system keeps hips and lumbar lifted rather than sinking, which is exactly what these positions need.

BEST FOR: Ideal for sleepers who need maximum spinal resistance, wake up stiff from sleeping on surfaces that are too soft, or prefer a flat firm feel with no sink.

CONSTRUCTION SPECIFICATIONS: The heavyweight knit quilt panel stretches to move with you without compressing the surface. Firm support foam beneath adds just enough cushion to take the edge off. The fabric-wrapped heavy gauge coil system pushes back firmly and keeps the spine from rounding. High-density upholstery grade foam at the base resists body impressions over time. Foams are CertiPUR-US® certified.

SETUP AND COMPATIBILITY: This bed-in-a-box arrives rolled and compressed, expands within hours, and requires no tools. Compatible with adjustable bases, platform frames, and box springs.

NOT A FIT FOR: Side sleepers who need hip and shoulder pressure relief, or anyone who prefers a plush or cushioning feel at the surface.
