Overview
Mancini's Sleepworld Granite Bay Extra Firm Mattress 13" Queen
⭐⭐⭐⭐⭐ 4.8 · 100+ verified sleepers
The Mancini's Sleepworld Granite Bay Extra Firm Mattress 13" is a foam mattress built for sleepers who need a firm mattress for back pain relief and refuse to let their spine sink overnight. Where most foam beds gradually give way under body weight, this one is engineered from the ground up to hold its position. The support core uses Ultra High Density Firm Memory Foam infused with Graphite, Copper, and Titanium, sitting above a Super High Density foam base built for long-term durability. If you've been waking up stiff because your mattress has lost its backbone, this is the answer. 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: Extra firm with a flat, stable surface that pushes back and holds the lumbar in place.
SIZE: This queen sized mattress is a versatile choice at 60 by 80 inches, ideal for couples or solo sleepers who want maximum space and structured support.
BEST SLEEP MATCH: Stomach and back sleepers will find that this extra firm mattress for back sleepers keeps the hips lifted and the lower back from collapsing into the foam throughout the night.
BEST FOR: Ideal for sleepers who need serious spinal support, tend to overheat, or have been waking up with lower back and hip discomfort.
CONSTRUCTION SPECIFICATIONS: The Cold stretch knit quilt panel actively pulls heat from the surface before it builds. Graphite, Copper, and Titanium-infused Ultra High Density memory foam layers contour firmly without trapping warmth. The Super High Density base foam underneath keeps this mattress from softening out after the first year.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Compatible with adjustable bases, platform frames, and box springs. No tools needed.
NOT A FIT FOR: Side sleepers who need hip and shoulder cushioning, or anyone who prefers even a medium level of pressure relief at the surface.
