Beautyrest Black Series Three Medium Mattress 15.25" Split Cal King

⭐⭐⭐⭐ 4.4 · 100+ verified sleepers

The Beautyrest Black Series Three Medium Mattress 15.25" is a hybrid mattress built for the sleeper who runs warm, wakes up stiff, or shares a bed with a restless partner. This is the best luxury hybrid mattress split cal king Beautyrest offers at the Series Three level, stacking latex, diamond-infused foam, and an advanced coil system into one refined sleep experience. Every layer earns its place here, and the result is a mattress that feels both cradling and cool from the first night. If you want to feel what separates this from everything else at the price, our sleep specialists at any Mancini's Sleepworld location will put it side by side with the competition and let the mattress speak for itself.

COMFORT AND FEEL: A true medium feel with a buoyant, contouring surface that cushions without the sluggish sink of traditional memory foam.

SIZE: This split cal king sized mattress is designed for taller couples who want independent adjustability on each side of the bed.

BEST SLEEP MATCH: Side and back sleepers will feel right at home on the medium firmness here. The latex layer lifts pressure off the shoulder and hip while the coil system keeps the spine from sagging through the night.

BEST FOR: Ideal for sleepers who share a bed with a restless partner, run warm at night, or wake up with hip and shoulder tension.

CONSTRUCTION SPECIFICATIONS: Sleep Climate™ Technology woven into the cover works to transfer heat away from the surface all night. SurfaceTouch™ Gel Memory Foam is quilted directly into the sleep surface for immediate pressure relief. Micro Diamond™ Memory Foam draws heat away from the body as you sleep. Self-Response™ Latex is ventilated to maximize airflow while contouring to your body in real time. Triple-Stranded Pocketed Coil® Technology delivers individualized support head to toe.

SETUP AND COMPATIBILITY: Compatible with adjustable bases, platform frames, and box springs. Delivered flat with in-home professional setup included; no tools needed.

NOT A FIT FOR: Sleepers who prefer a very firm, no-give surface, or strict stomach sleepers who need firmer lumbar resistance than a medium feel provides.
