Overview
Sealy Posturepedic Truett Firm Mattress 12.5" · Queen
The Sealy Posturepedic® Truett Firm Mattress 12.5" is an innerspring mattress built for back sleepers and stomach sleepers who need consistent, no-compromise support. A firm mattress for back pain relief demands a coil system that holds the lumbar in place rather than letting it sink, and that's exactly what the Truett Firm delivers night after night. The construction is straightforward and honest: no unnecessary layers, nothing to break down and disappoint you at year three.
The coil system works across the entire surface so the edges feel just as supportive as the center. The CoreSupport™ center reinforces the middle third of the mattress, which is where most of the body's weight lands. Stop by any Mancini's Sleepworld location and our sleep specialists will set the Truett Firm next to every competing option at this price so you can feel exactly where your body sits.
COMFORT AND FEEL: Firm and flat with an immediate, spring-forward response that keeps the spine aligned.
SIZE: This queen sized mattress is a versatile fit for guest rooms, solo sleepers, and couples who need their own side without encroaching on each other.
BEST SLEEP MATCH: Back sleepers and stomach sleepers will appreciate this firm innerspring. Firm support for back sleepers means the hips stay level and the lower back stops carrying extra tension through the night.
BEST FOR: Ideal for sleepers who need strong lumbar support, tend to sleep on their back or stomach, or have been sinking into their current mattress and waking up stiff.
CONSTRUCTION SPECIFICATIONS: The SealyStability™ encased coil system works edge to edge, so support is consistent across the full surface. The CoreSupport™ center adds reinforcement right where body weight concentrates. The StableEdge™ Pro system keeps the perimeter firm so no inch of the mattress is wasted. A knit cover with MoistureProtect and Surface-Guard Technology wicks moisture and resists surface wear.
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: Side sleepers who need hip and shoulder cushioning, or anyone looking for a plush or pillow-top feel at this firmness level.
