Sealy Posturepedic Truett Firm Mattress 12.5″

Sealy Posturepedic Truett Firm Mattress 12.5″ Queen

The Sealy Posturepedic Truett Firm Mattress is an innerspring mattress built for back and stomach sleepers who need a firm mattress for back pain relief and wake up stiff without proper lumbar support. The Posturepedic line draws on Sealy’s work alongside orthopedic specialists, and the Truett puts that legacy into a practical, dependable package at a price that makes sense. The 660-coil SealyStability™ support system works across the full surface so you never lose support near the edges. Stop by any Mancini’s Sleepworld location and our sleep specialists can put this next to competing options so you can feel the difference for yourself.

COMFORT AND FEEL: Firm feel with light foam cushioning and a coil-driven, sleep-on-top support response.

SIZE: This queen sized mattress is roomy enough for couples or single sleepers who move around and want a firm mattress for back sleepers without sacrificing usable surface space.

BEST SLEEP MATCH: Best for back and stomach sleepers who want firm support. The on-top feel keeps the hips from sinking, which helps the lumbar stay lifted and the spine stay neutral through the night.

BEST FOR: Ideal for sleepers who wake up with lower back tension, need consistent lumbar alignment, or prefer a mattress that holds its shape over years of use.

CONSTRUCTION SPECIFICATIONS: The SealyStability™ encased coil system with 660 coils provides full-surface support without soft spots. The CoreSupport™ center adds an extra layer of reinforcement where your body is heaviest. SealyComfort™ Air Foam and SealyComfort Gel Foam quilting layers take the edge off the firm feel. The MoistureProtect knit cover with Surface-Guard Technology™ helps keep the sleep surface cool and fresh.

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

NOT A FIT FOR: Not the best choice for side sleepers who need hip and shoulder cushioning, or for anyone who prefers a plush or pressure-relieving feel.
