Overview
Beautyrest Black Series Three Extra Firm Mattress 14.25" — Split Cal King
The Beautyrest Black® Series Three Extra Firm Mattress 14.25" is a luxury innerspring mattress built for back and stomach sleepers who need real lumbar support without any give at the hips. This is the firmest feel in the Beautyrest Black® line, engineered for the sleeper who wants to rest on top of the mattress rather than sink into it. Every layer earns its place: diamond-infused memory foam above the coil system draws warmth away from the body, while a ventilated Self-Response™ Latex layer adds just enough buoyancy to protect pressure points without softening the overall feel. If you want to feel this next to every competing option at the same price, stop in and one of our Mancini's Sleepworld sleep specialists will set that up for you.
COMFORT AND FEEL: Extra firm feel with a flat, buoyant surface that holds the body in alignment without any sinking.
SIZE: This Split Cal King sized mattress is designed for couples who want individual adjustability on a California King footprint, including adjustable base compatibility.
BEST SLEEP MATCH: Best for back and stomach sleepers. The extra firm feel for back pain relief keeps the hips from dropping, so the lumbar stays lifted and the spine rests in a neutral line all night.
BEST FOR: Ideal for sleepers who need firm lumbar support, run warm through the night, or share a bed and can't afford to feel every movement their partner makes.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology wraps each coil independently for precise, head-to-toe support. Micro Diamond™ Memory Foam pulls heat away from the body while contouring lightly to the surface. Self-Response™ Latex ventilates and responds instantly, protecting pressure points without softening the feel. SurfaceTouch™ Gel Memory Foam is quilted into the sleep surface for immediate relief at contact points. Sleep Climate™ Technology is woven into the cover to transfer heat all night.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup available. Compatible with adjustable bases, platform frames, and box springs. No tools needed for base assembly.
NOT A FIT FOR: Side sleepers who need significant hip and shoulder cushioning. Sleepers who prefer a plush or contouring feel may find this surface too rigid.
