Overview
Sleepworld Express 11" Innerspring Extra Firm Mattress, Full
The Sleepworld Express 11" Innerspring Extra Firm Mattress is an extra firm innerspring mattress built for back and stomach sleepers who need a surface that holds them up rather than letting them sink. The fabric-wrapped coil system uses super heavy-gauge wire to deliver the kind of unyielding lift that keeps the lumbar in line from the first night. High-density upholstery-grade support foam reinforces the base so the extra firm feel stays consistent year after year, not just through the first few months. A heavyweight 4-way stretch knit quilt panel finishes the top surface with just enough give to keep things comfortable. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to every competing option at this price point so you can feel the difference yourself.
COMFORT AND FEEL: Extra firm feel with a flat, lifted surface and rigid coil-driven support throughout.
SIZE: This full sized mattress is a smart fit for solo sleepers, teenagers, or a dedicated guest room that needs a dependable, space-efficient bed.
BEST SLEEP MATCH: Best for stomach and back sleepers who need a firm mattress for back pain relief. The unyielding coil system keeps the hips level so the lower back stops compensating overnight.
BEST FOR: Ideal for sleepers who need strict spinal support, tend to sleep on their stomach or back, or have struggled to find a surface firm enough to stop morning stiffness.
CONSTRUCTION SPECIFICATIONS: The fabric-wrapped coil system uses super heavy-gauge wire that pushes back firmly against body weight. High-density upholstery-grade support foam lines the base to keep the structure from compressing over time. The stretch knit quilt panel adds a thin comfort layer without softening the overall feel. Foams are CertiPUR-US certified.
SETUP AND COMPATIBILITY: This bed-in-a-box arrives rolled and compressed, expands to full height 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 cushioning, or anyone who finds firm surfaces uncomfortable for existing pressure point issues.
