Overview
Mancini's Sleepworld Granite Bay Firm Mattress 13" Split Cal King
The Mancini's Sleepworld Granite Bay Firm Mattress 13" is a firm memory foam mattress built for back sleepers and combination sleepers who need steady spinal support without sacrificing surface comfort. A Super Heavy Weight "Cold" stretch knit quilt panel sits right at the surface, pulling warmth away before it has a chance to settle in. Beneath it, ultra-high-density memory foam layers infused with graphite, copper, and titanium work through the night to reduce heat retention and keep the feel consistent from edge to edge. The super-high-density foam core underneath resists sagging so the support you feel on night one is still the support you get years later. Stop by any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the difference yourself.
COMFORT AND FEEL: Firm feel with a close, controlled surface that lifts the lumbar without locking the hips in.
SIZE: This Split Cal King sized mattress is designed for couples who want individual temperature and motion control on each side of a long, narrow California King footprint.
BEST SLEEP MATCH: Best for back sleepers and stomach sleepers who prefer a firm mattress for back pain relief. The firm surface keeps the pelvis from dropping, which takes pressure off the lower spine all night.
BEST FOR: Ideal for sleepers who run warm, need lumbar support through the night, or wake up stiff from a mattress that has lost its shape.
CONSTRUCTION SPECIFICATIONS: The "Cold" stretch knit surface feels cool the moment you lie down. Graphite, copper, and titanium-infused memory foam layers pull heat away from the body and firm up contouring around pressure points. The super-high-density base foam keeps the mattress from softening out, so back and stomach sleepers stay supported rather than cradled. Total height is 13 inches.
SETUP AND COMPATIBILITY: Works with adjustable bases, platform frames, and box springs. Delivered flat with white-glove in-home professional setup included. No tools needed.
NOT A FIT FOR: Side sleepers who need deep shoulder and hip cushioning may find the firm surface too unyielding. Not recommended for sleepers who prefer a plush or pillow-top feel.
