Mancini's Sleepworld Marina Firm Mattress 8" Eastern King

The Mancini's Sleepworld Marina Firm Mattress 8" is a firm mattress for back pain relief built for the sleeper who needs real, structural support without trading away surface comfort. A gel-infused memory foam comfort layer takes the edge off firmness while letting heat move away from the body. The dense support core underneath holds its shape where cheaper foam gives out first, keeping spinal alignment consistent night after night. If you've been waking up stiff or rolling toward the middle of your current mattress, this is worth feeling in person. Stop by any Mancini's Sleepworld location and a sleep specialist will put this right next to every competing option so you can feel the difference yourself.

COMFORT AND FEEL: Firm feel with a thin memory foam layer that softens pressure without giving under load.

SIZE: This Eastern King sized mattress is a spacious 76" x 80", a strong fit for couples or a single sleeper who moves freely through the night.

BEST SLEEP MATCH: Best for back and stomach sleepers who want a firm mattress for back sleepers. The flat, non-yielding surface keeps the hips from sinking and the lumbar from twisting out of alignment.

BEST FOR: Ideal for sleepers who need firm spinal support, run warm through the night, or have found softer mattresses leave them sore by morning.

CONSTRUCTION SPECIFICATIONS: The stretch knit cover is engineered to stay cool against the skin. Beneath it, a gel-infused memory foam layer absorbs pressure without trapping heat. A firm high-density support core and super high-density titanium-infused memory foam layer form the base. The foams are CertiPUR-US certified.

SETUP AND COMPATIBILITY: Works flat on a platform frame, adjustable base, or box spring. Delivered flat with in-home professional setup available from Mancini's Sleepworld.

NOT A FIT FOR: Sleepers who prefer a plush or medium feel, or side sleepers who need deep pressure relief at the hip and shoulder.
