Overview

Sleepworld Express 13" Innerspring Extra Firm Mattress · Twin

The Sleepworld Express 13" Innerspring Extra Firm Mattress is an innerspring mattress built for back sleepers and stomach sleepers who need a flat, lifted surface that holds the spine in line all night. At 13 inches tall, it delivers that flat, no-sink feel that extra-firm sleepers spend years searching for, paired with a gel-infused comfort layer that takes the edge off without softening the support beneath it. The foam layers are dense enough to stay consistent year after year, so this is not a mattress that feels different six months from now. If you want to feel the difference between this and a firm before you commit, the sleep specialists at Mancini's Sleepworld will set them side by side so you can decide with your own body.

COMFORT AND FEEL: Extra firm with a flat, stable surface and lifted lumbar support throughout the night.

SIZE: This twin sized mattress is a practical fit for a solo sleeper, a child's room, a guest bedroom, or a compact apartment space.

BEST SLEEP MATCH: Best for back sleepers and stomach sleepers who need an extra firm mattress for back pain relief. The flat, non-sinking surface keeps the hips from dropping and the lower back from rounding during sleep.

BEST FOR: Ideal for sleepers who wake up stiff from a mattress that sinks, need firm lumbar support, or have been told a harder surface suits their sleep posture.

CONSTRUCTION SPECIFICATIONS: The cover is a heavyweight stretch knit built to sleep cool from contact. Below it, a gel-infused foam layer adds a touch of cushion without changing the firm feel beneath. The 790 pocketed coils respond individually to reduce motion and support the spine. Dense high-density foam layers above and below the coil unit keep the structure stable and resist softening over time. Foams are CertiPUR-US certified.

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

NOT A FIT FOR: Not the right choice for side sleepers who need shoulder and hip cushioning, or anyone who prefers a mattress with noticeable contouring or sink.
