Overview
Mancini's Sleepworld Granite Bay Medium Mattress 13" | Full
The Mancini's Sleepworld Granite Bay Medium Mattress 13" is a foam mattress built for the sleeper who runs warm, wakes up stiff, or simply wants a medium-soft feel that holds up over time. At 13 inches tall, the Granite Bay Medium layers its support thoughtfully: a responsive upper zone handles the contouring work while a dense base foam underneath keeps the whole structure stable. If you've been searching for the best mattress for pressure point relief in a full size, this one is worth lying down on. Stop into any Mancini's Sleepworld location and our sleep specialists will put it next to every option in its class so you can feel the difference yourself.
COMFORT AND FEEL: Medium-soft feel with slow contouring memory foam and firm lift underneath.
SIZE: This full sized mattress is 54 inches wide and 75 inches long, a smart fit for a solo sleeper upgrading from a twin or furnishing a personal bedroom.
BEST SLEEP MATCH: Back sleepers and side sleepers who want a medium firm foam mattress in a full size will both find a home here. The soft memory foam cushions the shoulder and hip without letting the spine sag out of line.
BEST FOR: Ideal for sleepers who run hot at night, need hip and shoulder cushioning, or wake up feeling stiff through the lower back.
CONSTRUCTION SPECIFICATIONS: The Super Heavy Weight "Cold" stretch knit quilt panel moves heat away from the surface all night. Beneath it, soft memory foam infused with graphite, copper, and titanium draws warmth away from the body. Ultra high-density medium-firm foam layers transition into a super high-density base that resists softening season after season.
SETUP AND COMPATIBILITY: Works with an adjustable base, platform frame, or box spring. Delivered flat with professional in-home setup available.
NOT A FIT FOR: Sleepers who prefer a firm or extra-firm feel. Also not ideal for those who need a reinforced perimeter for edge-to-edge sleeping.
