Overview
Beautyrest Black Series Three Firm Mattress 15" · Full
The Beautyrest Black® Series Three Firm Mattress 15" is a luxury innerspring mattress built for back and stomach sleepers who need serious lumbar support without sacrificing comfort. As a firm mattress for back pain relief, it stacks three Series worth of technology into a single 15-inch profile: the deep coil foundation of Series One, the Micro Diamond™ Memory Foam cooling upgrade of Series Two, and the Self-Response™ Latex layer exclusive to Series Three. The result is a mattress that holds the spine level while still letting the hips and shoulders settle enough to wake up without tension. Stop by any Mancini's Sleepworld location and our sleep specialists will lay this next to every competing option at this firmness so you can feel the difference before you decide.
COMFORT AND FEEL: Firm feel with a shallow, responsive surface that holds alignment without letting you sink.
SIZE: This full sized mattress is a natural fit for solo sleepers who want more sleeping space without committing to a queen footprint.
BEST SLEEP MATCH: Back and stomach sleepers will find this firm mattress for back sleepers keeps the lumbar lifted and the hips level so you stop rolling inward and waking up stiff.
BEST FOR: Ideal for sleepers who run warm, need the spine to stay flat through the night, or wake up with persistent lower back tightness.
CONSTRUCTION SPECIFICATIONS: The Triple-Stranded Pocketed Coil® Technology moves independently under each part of your body, so one partner shifting doesn't pull the other out of sleep. Micro Diamond™ Memory Foam draws heat away from your body all night. Self-Response™ Latex contours and breathes simultaneously, easing pressure while keeping air moving. The quilted cooling cover actively transfers warmth away from the surface.
SETUP AND COMPATIBILITY: Delivered flat with white-glove in-home setup included. Compatible with adjustable bases, platform frames, and box springs.
NOT A FIT FOR: Dedicated side sleepers who need deep hip and shoulder cushioning, or anyone who strongly prefers the slow-sink feel of a plush memory foam mattress.
