Overview

Beautyrest® World Class™ Level 3 Extra Firm Mattress 14.25" — Eastern King

The Beautyrest® World Class™ Level 3 Extra Firm Mattress 14.25" is an extra firm innerspring mattress built for back and stomach sleepers who want solid spinal alignment without any sensation of sinking. This is Beautyrest's third-tier World Class model, meaning it brings a meaningful step up in coil density, foam layering, and cooling technology over the entry levels. If you've been waking up stiff or rolling toward center, the extra firm feel here is designed to fix both. Stop by any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the difference yourself.

COMFORT AND FEEL: Extra firm quilted innerspring feel with responsive surface contouring and deep lumbar lift.

SIZE: This Eastern King sized mattress is a generous fit for couples who want room to spread out without disturbing each other.

BEST SLEEP MATCH: Best for back and stomach sleepers who prefer an extra firm mattress for back pain relief. The firm, non-sinking surface keeps the spine level all night, so you wake up without the morning ache.

BEST FOR: Ideal for sleepers who need firm lumbar support, run warm at night, or share a bed and need consistent motion separation.

CONSTRUCTION SPECIFICATIONS: The 1000 Density Pocketed Coil® Technology responds to each side of the bed independently. World Class Relief™ HD Foam reacts to body temperature, easing pressure without softening the overall feel. SurfaceTouch™ Gel Memory Foam and Beautyrest ActiveResponse™ MAX Memory Foam add instant surface contouring. InfiniCool® MAX Technology and natural lux fibers pull heat away from the sleep surface. 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: Sleepers who prefer a plush or contouring feel, or those with significant hip and shoulder pressure needs, will likely be more comfortable in a softer model.
