Overview
Sealy Posturepedic Truett Firm Mattress 12.5" TwinXL
The Sealy Posturepedic Truett Firm Mattress 12.5" is an innerspring mattress built for the sleeper who needs a firm mattress for back pain relief and wakes up stiff without consistent lumbar reinforcement. Posturepedic engineering puts extra attention where it counts, with a reinforced center zone that keeps the spine aligned rather than letting the midsection sink. The feel is confident and stable, not punishing, so back and stomach sleepers get the resistance they need without sacrificing comfort. If you have questions about whether this firmness is right for your body type, 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: Firm and flat with a stable, on-top-of-the-mattress feel throughout the night.
SIZE: This Twin XL sized mattress is ideal for taller single sleepers, dorm setups, and adjustable base configurations in compact spaces.
BEST SLEEP MATCH: Back and stomach sleepers will feel right at home on this firm mattress for back sleepers. The flat, stable surface keeps hips lifted and the spine in a straight line from shoulder to heel.
BEST FOR: Ideal for sleepers who need firm lumbar reinforcement, prefer a no-sink surface, or want a dependable innerspring without excess cushioning.
CONSTRUCTION SPECIFICATIONS: The SealyStability™ encased coil system keeps each spring moving independently for targeted support across every sleep position. The CoreSupport™ center adds focused reinforcement in the lumbar zone where the body is heaviest. StableEdge Pro™ firms up the perimeter so the usable surface extends to the very edge. The moisture-wicking, antibacterial cover helps the sleep surface stay clean and fresh.
SETUP AND COMPATIBILITY: Delivered flat with professional in-home setup available. Compatible with adjustable bases, platform frames, and box springs. No tools required for setup.
NOT A FIT FOR: Not the right choice for side sleepers who need cushioning at the hip and shoulder, or for anyone who prefers a plush or pillow-top feel.
