Overview
Mancini's Sleepworld Diamond Luxury Firm Mattress 11.5" Twin XL
The Mancini's Sleepworld Diamond Luxury Firm Mattress 11.5" is an innerspring mattress built for back sleepers who need consistent spinal support without sacrificing surface comfort. The luxury firm feel sits at the firmer end of the comfort range while still providing enough cushion to take the edge off pressure points at the hips and shoulders. If you have ever woken up stiff on a mattress that felt too soft to actually hold your spine in place, this one is worth a close look. Stop by any Mancini's Sleepworld location and our sleep specialists will set this one next to competing options so you can feel the difference for yourself.
COMFORT AND FEEL: Luxury firm feel with surface cushion and a coil system that keeps the spine lifted throughout the night.
SIZE: This Twin XL sized mattress is 39 inches wide by 80 inches long, well suited for taller single sleepers, dorm rooms, and adjustable base setups.
BEST SLEEP MATCH: Back sleepers and some side sleepers who want a luxury firm innerspring with enough quilted softness to ease shoulder and hip pressure without losing lumbar support.
BEST FOR: Ideal for sleepers who need firm lumbar support, want motion separation on a solo-sized mattress, or carry tension in the lower back after a night on a softer bed.
CONSTRUCTION SPECIFICATIONS: The stretch-knit quilt panel wraps a layer of super soft quilt foam, so the surface gives just enough without going soft. Below that, 1.5 inches of medium firm HD comfort foam keeps your hips from sinking too deep. An 8-inch 790 pocketed coil system moves zone by zone to absorb motion. A 0.75-inch shock-absorbing HD base layer keeps the mattress stable and resistant to premature softening. Foams are CertiPUR-US certified.
SETUP AND COMPATIBILITY: Delivered flat with white-glove in-home setup available. Compatible with adjustable bases, platform frames, and box springs. No tools needed for setup.
NOT A FIT FOR: Sleepers who prefer a plush or pressure-melting feel may find the luxury firm support level too firm. Not designed for strict side sleepers with significant shoulder or hip sensitivity.
