Overview
Glacier Original Hybrid Medium Firm Mattress 12" · Eastern King
The Glacier Original Hybrid Medium Firm Mattress 12" is a hybrid mattress built for the sleeper who runs warm and wakes up with a stiff lower back. It layers a glacierTECH° cool-to-the-touch cover over CarbonICE graphite-infused memory foam that actively pulls heat away from the lumbar zone, where most of your body weight concentrates through the night. The ChiroZONE™ quilted cover adds a second pass of targeted support right where the spine needs it most. If you've been searching for a medium firm hybrid mattress for back pain relief, this is a mattress worth lying down on. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to every competing option so you can feel the difference for yourself.
COMFORT AND FEEL: Medium firm with a responsive, close-contour feel that keeps the spine level without locking you in place.
SIZE: This Eastern King sized mattress is built for couples or solo sleepers who want full room-to-stretch space without sacrificing edge-to-edge support.
BEST SLEEP MATCH: Best for back and combination sleepers. The medium firm feel keeps the hips from sinking too deep, so your spine stays neutral whether you're flat on your back or shifting through the night.
BEST FOR: Ideal for sleepers who overheat at night, need lumbar pressure relief, or share a bed and can't afford to feel every movement.
CONSTRUCTION SPECIFICATIONS: The glacierTECH° cover is cool to the touch from the first night. CarbonICE graphite-infused memory foam draws heat away from the lumbar zone while cushioning pressure points. ARCFlow ventilated gel foam beneath it keeps air moving through the comfort layers. Over 1,000 individually wrapped coils provide edge support and deep airflow through the base.
SETUP AND COMPATIBILITY: Arrives rolled and compressed in a box, expands within hours, no tools needed. Compatible with adjustable bases, platform frames, and box spring or foundation setups.
NOT A FIT FOR: Dedicated side sleepers with pronounced hip or shoulder sensitivity may find the medium firm feel under-cushioned. Sleepers under 130 lbs may experience the surface as firmer than intended.
