Overview
Beautyrest Black® Series Three Medium Mattress 15.25" · CalKing
The Beautyrest Black® Series Three Medium Mattress 15.25" is a luxury innerspring mattress built for the sleeper who runs warm, needs shoulder and hip relief, and wants a true medium feel without sacrificing support. This is Beautyrest's most refined quilted innerspring offering at the Series Three level, bringing together their full cooling stack and a ventilated latex layer that sets it apart from everything below it in the lineup. The result is a mattress that feels cushioned and breathable at the surface while staying structured enough through the night. Stop by any Mancini's Sleepworld location and a sleep specialist will place this directly alongside every comparable option so you can feel the difference in person.
COMFORT AND FEEL: True medium feel with responsive latex cushioning and pocketed coil support underneath.
SIZE: This California King sized mattress is a strong fit for taller couples or solo sleepers who want generous room to stretch out.
BEST SLEEP MATCH: Side and combination sleepers will find this medium feel particularly well-suited to them. The latex and gel foam layers relieve pressure at the hips and shoulders while the coil system keeps the spine from sinking out of alignment.
BEST FOR: Ideal for sleepers who run hot at night, experience hip or shoulder pressure, or share a bed and need strong motion separation.
CONSTRUCTION SPECIFICATIONS: Sleep Climate™ Technology tops the surface with a cooling yarn cover designed to transfer heat away continuously. SurfaceTouch™ Gel Memory Foam is quilted directly into the surface for immediate pressure relief. Micro Diamond™ Memory Foam draws warmth away from the body while you sleep. Self-Response™ Latex provides ventilated, responsive contouring throughout the night. Triple-Stranded Pocketed Coil® Technology delivers individualized support head to toe.
SETUP AND COMPATIBILITY: Delivered flat with white-glove in-home professional setup included. Compatible with adjustable bases, platform frames, and box springs.
NOT A FIT FOR: Sleepers who prefer a deep, slow-sinking memory foam feel may find the latex response too buoyant. Those seeking a firm or extra-firm surface will want to consider a different comfort level.
