Overview

Beautyrest® World Class™ Level 3 Extra Firm Mattress 14.25" TwinXL

The Beautyrest® World Class™ Level 3 Extra Firm Mattress 14.25" is an innerspring mattress built for back and stomach sleepers who need an extra firm mattress for back pain relief without giving up surface comfort. At its core, 1000 Density Pocketed Coil® Technology delivers individualized support that keeps the spine aligned while limiting motion transfer across the bed. World Class Relief™ HD Foam responds to body temperature to ease pressure along the lumbar and hips, and InfiniCool® MAX Technology combined with breathable natural lux fibers moves heat away from the surface so you wake up feeling like you actually slept. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to every competing option so you can feel the difference for yourself.

COMFORT AND FEEL: Extra firm feel with responsive pressure relief that supports without compressing.

SIZE: This Twin XL sized mattress is the go-to choice for solo sleepers in smaller rooms, college settings, or adjustable base setups.

BEST SLEEP MATCH: Built for back and stomach sleepers who want a firm mattress for back sleepers without the locked-in, rigid feel. The extra firm surface keeps hips lifted and the lumbar supported all night.

BEST FOR: Ideal for sleepers who need strong spinal support, tend to overheat, or wake up with lower back and hip tension.

CONSTRUCTION SPECIFICATIONS: The 1000 Density Pocketed Coil® system moves with each part of your body independently. SurfaceTouch™ Gel Memory Foam and World Class Relief™ HD Foam respond to your body's warmth to ease pressure without the sinking sensation. Extra Firm HD Comfort Foam maintains the mattress's firm character. Beautyrest ActiveResponse™ MAX Memory Foam rounds out the comfort stack with contouring that bounces back quickly. Foams are CertiPUR-US® certified.

SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Compatible with adjustable bases, platform frames, and box springs. No tools needed.

NOT A FIT FOR: Not the right choice for side sleepers who need deep hip and shoulder cushioning, or for anyone who prefers a plush or pillow-top feel.
