Overview
Beautyrest Black Series One Medium Mattress 14.25" Twin XL
The Beautyrest Black® Series One Medium Mattress 14.25" is a hybrid mattress built for the sleeper who runs warm and wakes up needing more support from their bed. At 14.25 inches tall, it delivers the foundational Beautyrest Black® experience: gel memory foam that contours where your body asks for relief, a coil system engineered to respond to each point of contact independently, and Sleep Climate™ Technology woven throughout to keep the surface temperature from climbing overnight. It sits at the entry point of the Beautyrest Black® collection, giving you everything that defines the line without the added layers of the upper series. Stop by any Mancini's Sleepworld location and a sleep specialist will place this next to every competing option so you can feel the difference yourself.
COMFORT AND FEEL: Medium firmness with a cushioned surface feel and responsive coil lift underneath.
SIZE: This Twin XL sized mattress is an ideal fit for taller solo sleepers, college students, and adjustable base setups.
BEST SLEEP MATCH: Back and side sleepers who want medium hybrid cooling comfort will find this Twin XL supportive without feeling rigid, with enough contouring at the shoulders to stay comfortable through the night.
BEST FOR: Ideal for sleepers who run warm, need hip and shoulder pressure relief, or want individualized support without waking their partner.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology responds to each part of your body independently, keeping motion on one side from reaching the other. Beautyrest® Gel Memory Foam draws heat away while contouring your hips and shoulders. AirCool® HD Foam and AirFeel® Foam add breathable cushion underneath the surface.
SETUP AND COMPATIBILITY: Arrives flat and is compatible with adjustable bases, platform frames, and box springs. Professional in-home setup is available through Mancini's Sleepworld.
NOT A FIT FOR: Strict stomach sleepers who need a firmer feel, or sleepers under 130 lbs who may not engage the pressure-relieving layers fully.
