Sleepworld Express 13" Memory Foam Extra Firm Mattress, Full

⭐⭐⭐⭐⭐ 5.0 · 5+ verified sleepers

The Sleepworld Express 13" Memory Foam Extra Firm Mattress is a foam mattress built for the sleeper who needs maximum spinal support without any give-and-sink feeling. This is the extra firm mattress for back pain relief that chronic back and stomach sleepers have been asking for: an unyielding surface that keeps hips lifted, the lumbar supported, and the spine straight from the first hour to the last. The Alpine Firm support core is the engine here, stacking Ultra High Density memory foam infused with Graphite, Copper, and Titanium above a Super High-Density foam base that is engineered to hold its structure long after softer mattresses have given out. Stop by any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the exact difference yourself.

COMFORT AND FEEL: Extra firm memory foam with a cold-touch surface and unyielding lumbar support throughout the night.

SIZE: This full sized mattress is a smart fit for solo sleepers, teenagers, and single adults who want a dedicated support-focused sleep surface in a space-efficient room.

BEST SLEEP MATCH: Built for back sleepers and stomach sleepers who want a firm mattress for back sleepers. The non-yielding extra firm feel keeps the hips from dropping and the lower back from arching overnight.

BEST FOR: Ideal for sleepers who need maximum spinal alignment, tend to sink through softer mattresses, or wake up with persistent lower back or hip tension.

CONSTRUCTION SPECIFICATIONS: The Super Heavy Weight "Cold" stretch knit quilt panel draws heat away from the surface the moment you lie down. Ultra High Density memory foam infused with Graphite, Copper, and Titanium sits at the core, offering body-contouring firmness without softening. A Super High-Density foam base anchors everything, keeping this mattress from losing its shape.

SETUP AND COMPATIBILITY: Ships bed-in-a-box style, arriving rolled and compressed. It expands within hours, no tools required, and is compatible with adjustable bases, platform frames, and box springs.

NOT A FIT FOR: Side sleepers who need hip and shoulder cushioning will likely find this too rigid. Sleepers seeking any plush or medium-feel surface should explore a softer option.
