Overview
Beautyrest Black® Series Three Firm Mattress 15" Cal King
The Beautyrest Black® Series Three Firm Mattress 15" is a hybrid mattress built for back and stomach sleepers who want a firm mattress for back pain relief without sacrificing the refined comfort the Black® collection is known for. Triple-Stranded Pocketed Coil® Technology works independently under each part of your body, so your spine stays supported no matter how the night shifts. Micro Diamond™ Memory Foam adds a layer of cooling above the coils, pulling heat away before it interrupts your sleep. The Series Three sits a step above the Series Two with added conforming support built into every layer. 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 for yourself.
COMFORT AND FEEL: Firm feel with responsive surface support and stable, lift-focused lumbar control.
SIZE: This California King sized mattress is ideal for taller sleepers and couples who want generous sleeping space in a dedicated master bedroom.
BEST SLEEP MATCH: Best for back and stomach sleepers. The firm mattress for back sleepers feel keeps the hips from sinking, so your spine stays level from shoulder to heel all night.
BEST FOR: Ideal for sleepers who need strong lumbar support, run warm through the night, or share a bed and want to stay undisturbed by a partner's movement.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology moves with each part of your body independently. Micro Diamond™ Memory Foam pulls heat away from the surface as you sleep. Sleep Climate™ Technology uses cooling yarn and specialized vertical fibers woven into the mattress cover to transfer heat continuously. Self-Response™ Latex conforms to your pressure points while keeping airflow moving through the comfort layer.
SETUP AND COMPATIBILITY: Delivered flat with white-glove in-home setup included. Compatible with adjustable bases, platform frames, and box springs with proper center support.
NOT A FIT FOR: Dedicated side sleepers who need deep pressure relief at the hip and shoulder may find this firm feel too unyielding for comfortable all-night rest.
