Sleepworld Express 11.5″ Innerspring Medium Firm Mattress

Sleepworld Express 11.5″ Innerspring Medium Firm Mattress Queen

The Sleepworld Express 11.5″ Innerspring Medium Firm Mattress is a medium firm innerspring mattress built for the back sleeper who needs dependable lumbar support without waking up feeling like they slept on a board. It earns its place in a crowded value category by pairing genuine coil-based support with comfort foam that actually does something, not just softens the surface. If you have been shopping a medium firm mattress for back pain relief and want something that holds its shape year after year, this one is worth lying on. Stop by any Mancini’s Sleepworld location and a sleep specialist will put this next to every comparable option so you can feel the difference before you decide.

COMFORT AND FEEL: Medium firm with a responsive, slightly lifted feel that keeps the spine supported all night.

SIZE: This queen sized mattress is a generous 60 by 80 inches, a strong fit for couples sharing a master bedroom or solo sleepers who like room to stretch.

BEST SLEEP MATCH: Built for back sleepers, and some side sleepers who prefer a firmer surface. The medium firm feel keeps the hips from sinking while still taking the edge off pressure points at the shoulders.

BEST FOR: Ideal for sleepers who wake up with lower back stiffness, want a responsive coil feel instead of foam sink, or need a mattress that holds its shape through years of use.

CONSTRUCTION SPECIFICATIONS: The stretch knit quilt panel moves with you rather than pulling tight when you shift positions. Beneath it, 1.5 inches of medium firm high-density comfort foam cushions without going soft. An 8-inch, 790-pocketed coil system handles targeted support and keeps motion from traveling across the bed. A shock-absorbing high-density base layer holds everything in place so the support feels consistent well past the first year. Foams are CertiPUR-US certified.

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

NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel will find this too firm. Those needing a soft pressure-relief surface for side sleeping at the hip should consider a softer option.
