Overview
Sleepworld Express 11.5" Innerspring Medium Firm Mattress · Full
The Sleepworld Express 11.5" Innerspring Medium Firm Mattress is a medium firm innerspring mattress built for the sleeper who needs reliable spinal support but still wants a surface with some give. It is a strong value choice for anyone who has been waking up stiff or restless on an aging bed. The pocketed coil support system keeps the lumbar lifted through the night, and the high-density foam layers above it resist body impressions so the feel stays consistent over time. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to other options so you can feel the difference yourself before you commit.
COMFORT AND FEEL: Medium firm feel with a resilient surface that supports the spine without feeling rigid.
SIZE: This full sized mattress is a practical fit for solo sleepers, older teens, or a dedicated guest room.
BEST SLEEP MATCH: Back sleepers and some side sleepers tend to find medium firm innerspring mattresses with a medium firm feel exactly right, keeping hips from sinking while allowing the shoulders just enough contour to stay comfortable.
BEST FOR: Ideal for sleepers who wake up with lower back tension, want dependable coil support, or need a no-fuss bed-in-a-box setup.
CONSTRUCTION SPECIFICATIONS: A heavyweight 4-way stretch knit cover keeps the surface flexible and breathable. The 1.5" medium firm H.D. comfort layer cushions without letting you sink. An 8" 790 pocketed coil system supports your lumbar and reduces motion transfer. A shock-absorbing H.D. base keeps the mattress stable and resistant to early softening. Foams are CertiPUR-US certified.
SETUP AND COMPATIBILITY: This mattress ships rolled and compressed in a box, expands within hours, and requires no tools. Compatible with adjustable bases, platform frames, and box springs.
NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel, or those who need a very firm surface for orthopedic support needs.
