Overview

Helix Core Midnight Medium Euro-Top Mattress 12.5" Eastern King

The Helix Core Midnight Medium Euro-Top Mattress 12.5" is a hybrid mattress built for side sleepers who wake up stiff and run warm through the night. It pairs contouring Gel Memory Foam with a coil system that keeps you lifted rather than swallowed, making it one of the better medium firm mattresses for back pain relief among entry-level hybrids. The GlacioTex™ Cooling Cover is included as standard on this model, drawing heat away from the surface the moment you lie down. Responsive Foam layers sit between the gel comfort zone and the coil core, keeping the feel balanced without going too soft or too firm. Stop by any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the difference for yourself.

COMFORT AND FEEL: Medium feel with memory foam contouring and coil-driven rebound beneath.

SIZE: This Eastern King sized mattress is a spacious 76 by 80 inches, ideal for couples and solo sleepers who want room to move.

BEST SLEEP MATCH: Side and back sleepers will get the most from this medium hybrid mattress Eastern King. The Gel Memory Foam cushions shoulders and hips while the coil core keeps the spine from dipping out of alignment.

BEST FOR: Ideal for sleepers who run warm, carry tension in the hips and shoulders, or share a bed and need reliable motion separation.

CONSTRUCTION SPECIFICATIONS: The GlacioTex™ Cooling Cover pulls heat away from the surface for a cool-to-the-touch feel. Gel Memory Foam cradles pressure points at the hips and shoulders without letting you sink too deep. Responsive Foam layers define the medium feel and keep the mattress lively underfoot. Individually wrapped steel coils absorb motion and support the body. DuraDense Foam anchors the base so the mattress holds its shape long-term.

SETUP AND COMPATIBILITY: Arrives rolled and compressed in a box, expands within hours, no tools needed. Works with adjustable bases, platform frames, and box springs. Professional in-home setup is available.

NOT A FIT FOR: Stomach sleepers who need firm lumbar lift may find the medium feel lets the hips sink too far. Sleepers over 230 lbs may want to consider a firmer or more supportive model.
