Overview
Glacier Original Hybrid Medium Firm Mattress 12" Cal King
The Glacier Original Hybrid Medium Firm Mattress 12" is a hybrid mattress built for the back sleeper who overheats and wakes up with a tight lower back. It layers graphite-infused memory foam, ARCFlow® foam, and a deep coil unit under a cool-to-the-touch cover so your lumbar zone stays supported and your body temperature stays in check. That combination hits a firmness level that back and combination sleepers tend to feel immediately. If you want to feel this next to every competing option before you commit, stop by any Mancini's Sleepworld location and one of our sleep specialists will walk you through it personally.
COMFORT AND FEEL: Medium firm with a responsive, lightly cradling feel and steady lumbar lift throughout the night.
SIZE: This Cal King sized mattress is ideal for tall couples or solo sleepers who want full range of motion and prefer sprawling out across a wider sleep surface.
BEST SLEEP MATCH: Best for back sleepers and combination sleepers seeking a medium firm hybrid mattress Cal King. The coil base keeps your hips from sinking while the foam layers ease pressure at the shoulders, so position changes feel natural rather than forced.
BEST FOR: Ideal for sleepers who run hot at night, need lumbar support to stop waking up stiff, or want a calmer surface when sharing the bed.
CONSTRUCTION SPECIFICATIONS: The glacierTECH° quilted cover is cool to the touch from the moment you lie down. CarbonICE graphite-infused memory foam draws heat away and firms up the lumbar zone so your lower back stays lifted. ARCFlow® foam beneath it cushions without trapping warmth. Over 1,000 individually wrapped coils handle airflow, edge support, and motion. A dense base layer keeps all of it from shifting over time. CertiPUR-US® certified foams throughout.
SETUP AND COMPATIBILITY: Arrives rolled and compressed in a box and expands within hours, no tools needed. Compatible with adjustable bases, platform frames, and box springs with a foundation for proper support.
NOT A FIT FOR: Dedicated side sleepers who prefer a plusher, pressure-forward feel may find the medium firm profile firmer than they want. Not ideal for sleepers who prefer a pillowtop-soft surface.
