Overview
Beautyrest Black® Series One Extra Firm Mattress 13.5" Twin XL
The Beautyrest Black® Series One Extra Firm Mattress 13.5" is a quilted innerspring mattress built for back and stomach sleepers who need a firm, non-negotiable surface that holds the spine straight from the first hour to the last. It pairs Triple-Stranded Pocketed Coil® Technology with layers of premium gel memory foam to deliver an extra firm mattress for back pain relief that never trades support for softness. Every coil moves independently, so the person next to you barely registers on your side. Stop by any Mancini's Sleepworld location and our sleep specialists will lay this out beside every comparable option so you can feel the difference in real time.
COMFORT AND FEEL: Extra firm and responsive with a flat, on-top-of-the-mattress feel and steady lumbar lift.
SIZE: This Twin XL sized mattress is a natural fit for taller solo sleepers, college students, and adults in adjustable bed setups who need the length without a full width.
BEST SLEEP MATCH: Built for back and stomach sleepers who want an extra firm surface. The unyielding coil base keeps hips from sinking and holds the pelvis level, which is exactly what stomach sleepers need to wake up without tension across the lower back.
BEST FOR: Ideal for sleepers who need strict spinal support, tend to overheat through the night, or share a bed and want their rest undisturbed by movement.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology delivers individualized, head-to-toe support and absorbs motion so it stays on your partner's side. Gentle Support™ Foam and AirCool® HD Foam work together to move air through the mattress as you sleep. Beautyrest® Gel Memory Foam contours just enough for pressure relief without undermining the firm feel. Sleep Climate™ Technology transfers heat away from your body throughout the night.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup available. Works with an adjustable base, platform frame, or box spring. No tools needed on your end.
NOT A FIT FOR: Side sleepers who need deep hip and shoulder cushioning, or anyone who prefers a mattress that contours and cradles rather than supports from below.
