Overview

Beautyrest® World Class™ Level 4 Medium Tight Top Mattress 15" · Twin XL

The Beautyrest® World Class™ Level 4 Medium Tight Top is a quilted innerspring mattress built for the sleeper who wants genuine pressure relief without the sinking, swallowed-up feeling of a softer bed. At 15 inches, it sits in the premium tier of the World Class™ lineup, bringing the full complement of Level Four comfort layers that set it apart from the models below it. The construction is designed to respond to how your body actually generates heat and pressure rather than simply cushioning you from above. Stop by any Mancini's Sleepworld location and a sleep specialist will put this one next to every competing option in the same feel category so you can compare for yourself.

COMFORT AND FEEL: Medium support with structured surface cushioning that lifts without sinking.

SIZE: This Twin XL sized mattress is a natural fit for taller solo sleepers, college students, and single adults who want a full-depth mattress without a larger footprint.

BEST SLEEP MATCH: Back and stomach sleepers who want medium support with pressure relief will feel at home here. The tight top holds its shape so your hips stay level and your spine stays supported through the night.

BEST FOR: Ideal for sleepers who run warm at night, carry tension through the shoulders and neck, or want pressure relief without the deep sink of a plush bed.

CONSTRUCTION SPECIFICATIONS: The InfiniCool® MAX sleep surface pulls heat away and natural lux fibers add breathability. World Class Relief™ HD Foam responds to body temperature for targeted pressure relief. SurfaceTouch™ Gel Memory Foam is quilted directly into the surface for immediate comfort. Beautyrest ActiveResponse™ MAX Memory Foam contours to ease aches. The 1000-density Pocketed Coil® system moves with you, not against you.

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

NOT A FIT FOR: Not the best choice for sleepers who prefer a deep plush feel or significant contouring sink. The tight top construction keeps the surface firmer and more structured by design.
