Overview
Beautyrest Black Series Two Firm Mattress 14.25" Twin XL
★★★★★ 5.0 · 1+ verified sleepers
The Beautyrest Black® Series Two Firm Mattress 14.25" is a luxury innerspring mattress built for back and stomach sleepers who want serious support without giving up refined comfort. It steps up from Series One with multiple layers of premium High-Density Memory Foam and specialized gel memory quilted directly into the sleep surface, so pressure relief kicks in the moment you lie down. Micro Diamond™ Memory Foam adds an extra layer of cooling, pulling warmth away from the body while you sleep. The result is a firm mattress for back pain relief that doesn't feel punishing. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to every competing option so you can feel exactly what this firmness level does for your body.
COMFORT AND FEEL: Firm and responsive with a cushiony top that yields briefly before firm underlying support takes over.
SIZE: This Twin XL sized mattress is a strong fit for taller individuals, college students, or solo sleepers who want full-length luxury support.
BEST SLEEP MATCH: Best for back and stomach sleepers. The firm mattress for back sleepers feel keeps hips and lumbar in alignment so you stop waking up stiff.
BEST FOR: Ideal for sleepers who run warm at night, need spinal alignment support, or want motion-absorbing coils that don't transfer a partner's movement.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology uses three braided steel strands per coil, so each one responds independently to your body. Gel memory foam quilted into the sleep surface delivers immediate pressure relief. Micro Diamond™ Memory Foam pulls heat away from the body. Sleep Climate™ Technology works with the surface and foam layers to keep temperature in check all night.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional 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 contouring feel will find this too firm. Strict side sleepers may notice increased shoulder pressure.
