Overview
Mancini's Sleepworld Granite Bay Extra Firm Mattress 13" · Full
The Mancini's Sleepworld Granite Bay Extra Firm Mattress 13" is a foam mattress built for the sleeper who needs firm, unwavering back support and wakes up stiff when a mattress gives too much. It is an extra firm mattress for back pain relief, engineered with multiple layers of ultra-high-density memory foam loaded with Graphite, Copper, and Titanium to keep heat moving away from your body even on the coldest-feeling night. A super heavy-weight stretch knit quilt panel sits at the surface, actively moderating temperature so the bed never turns into a heat trap. Stop by any Mancini's Sleepworld location and our sleep specialists will place this next to every competing option so you can feel the difference for yourself.
COMFORT AND FEEL: Extra firm feel with dense foam layers that support rather than contour.
SIZE: This full sized mattress is 54 inches wide by 75 inches long, a practical fit for a single adult sleeper or a compact guest room setup.
BEST SLEEP MATCH: Best for back and stomach sleepers who prefer a firm mattress for back pain relief. The non-yielding surface keeps the hips lifted and the lumbar from sinking overnight.
BEST FOR: Ideal for sleepers who want deep spinal support, tend to sleep hot, or need a mattress that holds its shape year after year.
CONSTRUCTION SPECIFICATIONS: The quilted cover uses a super heavy-weight cold stretch knit that pulls warmth away from the surface. Beneath it, ultra-high-density memory foam infused with Graphite, Copper, and Titanium works to dissipate body heat while firming around your frame. A super high-density foam core anchors everything, keeping the structure stable and resistant to breakdown.
SETUP AND COMPATIBILITY: Compatible with adjustable bases, platform frames, and box springs. Delivered flat with professional in-home setup included at no extra charge.
NOT A FIT FOR: Not recommended for side sleepers who need hip and shoulder cushioning, or anyone who prefers a plush or contouring feel.
