Overview
Sleepworld Express 11.5" Innerspring Medium Firm Mattress, Eastern King
The Sleepworld Express 11.5" Innerspring Medium Firm Mattress is an innerspring mattress built for the back sleeper who wants a firm foundation without sacrificing surface comfort. Engineered with a medium firm support foam comfort layer sitting beneath a heavyweight 4-way stretch knit cover, this mattress holds your spine in a neutral position from the moment you lie down. The pocketed coil system wraps each coil individually in fabric so they respond independently, giving you localized lift right where your body needs it most. Stop by any Mancini's Sleepworld location and one of our sleep specialists will walk you through how this sits next to the other options on the floor.
COMFORT AND FEEL: Medium firm feel with controlled push-back and stable lumbar support throughout the night.
SIZE: This Eastern King sized mattress is generously proportioned for couples or taller sleepers who want full stretch-out room without crowding.
BEST SLEEP MATCH: Best for back sleepers and some side sleepers. The medium firm innerspring mattress for back pain relief gives you enough surface response to keep hips aligned without letting the lower back sag.
BEST FOR: Ideal for sleepers who need consistent spinal support, want reduced motion transfer from a partner, or prefer a mattress that holds its shape year after year.
CONSTRUCTION SPECIFICATIONS: The 8" 790-count pocketed coil layer gives each spring room to respond on its own. A 1.5" medium firm comfort foam layer cushions the surface without letting you sink. The shock-absorbing high-density base foam keeps the mattress from softening out after the first year. 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: Sleepers who prefer a plush or pressure-relieving sink-in feel may find the medium firm surface too resistant. Not recommended for strict side sleepers needing deep hip and shoulder cushioning.
