Overview
Glacier Original Hybrid Medium Firm Mattress 12" Twin XL
The Glacier Original Hybrid Medium Firm Mattress 12" is a hybrid mattress built for the back sleeper who runs warm and wakes up stiff. Cooling starts at the surface with the glacierTECH° cover and works through every layer below, so the temperature stays steady from the moment you lie down. The CarbonICE graphite-infused memory foam sits directly under the quilt in the lumbar zone, drawing heat away from the area where most sleepers carry the most weight. A dense, stable base holds all of it in place so the feel you buy on day one is the same feel you get a year later. Stop by any Mancini's Sleepworld location and a sleep specialist will lay this down next to every competing hybrid so you can feel exactly what medium firm means on this mattress.
COMFORT AND FEEL: Medium firm with a cool initial touch, responsive lift, and steady lumbar support.
SIZE: This Twin XL sized mattress is well matched for college students, taller single sleepers, or anyone who needs the extra length without the extra width.
BEST SLEEP MATCH: Best for back sleepers and combination sleepers. The medium firm hybrid mattress Twin XL feel keeps the hips level and the lumbar supported, so you stop waking up with that low dull ache across the lower back.
BEST FOR: Ideal for sleepers who run hot at night, need lower back support, or tend to wake up stiff and unrested by morning.
CONSTRUCTION SPECIFICATIONS: The glacierTECH° cover is cool to the touch the second you reach for it. The ChiroZONE quilted layer focuses extra support right at the lumbar zone. CarbonICE graphite-infused memory foam draws heat away while relieving pressure at the center. ARCFlow ventilated foam below that keeps air moving through the core. Individually wrapped coils anchor the base, reinforce the edges, and let air circulate freely. CertiPUR-US® certified foams throughout.
SETUP AND COMPATIBILITY: Arrives rolled and compressed in a box, expands within hours, no tools needed. Compatible with adjustable bases, solid platform frames, and box springs.
NOT A FIT FOR: Lightweight side sleepers chasing a deep plush feel may find this too firm. Not designed for those who prefer a pillowtop-style sink.
