Mancini's Sleepworld Granite Bay Medium Mattress 13"
The Mancini's Sleepworld Granite Bay Medium Mattress 13" is a foam mattress built for the sleeper who runs warm and wakes up feeling like they fought the mattress all night. Its medium firmness sits right where pressure relief and lumbar support stop trading against each other, with cooling built into the foam, not just the cover.
Why this Mattress?
- Built for sleepers who sleep warm and wake up stiff
- Graphite, copper and titanium memory foam eases pressure
- "Cold" stretch knit cover pulls heat away from the surface
- Dense foam core holds its shape over the long haul
- Medium feel suits back and side sleepers who need lift
Comfort and feel: Medium firmness with a soft memory foam surface and a supportive, resilient base beneath.
Best sleep match: Back and side sleepers. Keeps the lumbar from dropping while hips and shoulders ease in without bottoming out.
Best for: Sleepers who tend to overheat, carry tension in the lower back, or need pressure relief at the hip and shoulder without losing support.
Construction: Super heavy weight "Cold" stretch knit quilt panel over ultra high density medium firm and soft memory foam layers infused with Graphite, Copper and Titanium, on a super high density foam core.
Setup and compatibility: Works on an adjustable base, platform frame or box spring. Delivered flat.
Not a fit for: Sleepers who prefer a very firm, minimal-contour feel.
