Overview
Mancini's Sleepworld Granite Bay Medium Mattress 13" · Cal King
The Mancini's Sleepworld Granite Bay Medium Mattress 13" is a foam mattress built for the sleeper who runs warm, wakes up stiff, and needs consistent support that holds its shape year after year. At 13 inches, this is one of the fuller builds in the Mancini's Sleepworld lineup, and the medium feel sits squarely between plush and firm, so your hips and shoulders get relief without the sensation of sinking in. The layering here is deliberate: softer memory foam on top for contouring, a denser transition layer underneath to stop that bottoming-out feeling, and a high-density base that keeps everything honest long-term. If you'd like to feel this next to the other Granite Bay firmness options, stop by any Mancini's Sleepworld location and a sleep specialist will walk you through the differences side by side.
COMFORT AND FEEL: Medium feel with contouring memory foam and steady lumbar support underneath.
SIZE: This Cal King sized mattress is 72 inches wide by 84 inches long, giving taller sleepers and couples the extra length they need without crowding the room.
BEST SLEEP MATCH: Back sleepers and combination sleepers will feel most at home here. The medium firmness keeps the lumbar supported while the soft memory foam layers cushion the shoulders when you roll to your side.
BEST FOR: Ideal for sleepers who run hot, need hip and shoulder pressure relief, or want a foam mattress that holds its support past the first year.
CONSTRUCTION SPECIFICATIONS: The cover uses a Super Heavy Weight "Cold" stretch knit quilt panel that pulls warmth away from the surface as you sleep. Memory foam infused with graphite, copper, and titanium works underneath to continue dispersing heat through the night. An ultra high-density medium firm foam layer transitions smoothly into a super high-density base that resists body impressions over time.
SETUP AND COMPATIBILITY: Works with an adjustable base, platform frame, or box spring. Delivered flat with professional in-home setup included, no tools required on your end.
NOT A FIT FOR: Strict stomach sleepers may find the medium feel allows more hip sink than ideal. Sleepers who prefer a very firm, minimal-contour surface should consider the Granite Bay Firm instead.
