Beautyrest Black Series Three Firm Mattress 15″

Beautyrest Black Series Three Firm Mattress 15″ Queen

The Beautyrest Black® Series Three Firm Mattress is a luxury hybrid built for back and stomach sleepers who need firm, stable support without sacrificing the kind of refined comfort you expect at this level. It builds on the full Series One and Series Two feature sets, then adds Micro Diamond™ Memory Foam and a coil system engineered to keep the spine level through every hour of the night. 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 yourself.

COMFORT AND FEEL: Firm feel with responsive surface cushioning and steady lumbar support beneath.

SIZE: This queen sized mattress is a strong fit for couples and solo sleepers who want a dedicated back support surface with room to move.

BEST SLEEP MATCH: Firm feel works especially well for back and stomach sleepers. The stable coil base keeps the hips from sinking so the spine stays aligned through the night.

BEST FOR: Ideal for sleepers who need firm back support, want to stay cool through the night, or share a bed and can’t afford to be woken by movement.

CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology responds individually under each part of your body. Micro Diamond™ Memory Foam pulls heat away from the surface while you sleep. Self-Response™ Latex contours to your pressure points and keeps airflow moving. Cooling yarn woven into the mattress surface adds another layer of overnight heat transfer.

SETUP AND COMPATIBILITY: Arrives flat via white-glove delivery. Works with an adjustable base, platform frame, or box spring. In-home professional setup is included.

NOT A FIT FOR: Sleepers who prefer a plush or pressure-cradling feel. Not the right choice if a medium or softer firmness has felt better in the past.
