Overview
Sealy Posturepedic Truett Firm Mattress 12.5" Split Cal King
The Sealy Posturepedic Truett Firm Mattress 12.5" is an innerspring mattress built for back and stomach sleepers who need a firm mattress for back pain relief and wake up stiff without solid spinal support beneath them. Posturepedic-engineered coils distribute weight evenly across the sleep surface so your lower back stays in a neutral position through the night. A reinforced center zone targets the area that carries the most load, giving your core the lift it needs to stop that morning ache before it starts. If you have been sleeping on a mattress that has softened out over time and your back knows it, this is the one to feel in person. Stop by any Mancini's Sleepworld location and our sleep specialists will put this right next to every competing option so you can feel the difference yourself.
COMFORT AND FEEL: Firm innerspring feel with minimal give and strong lumbar support throughout.
SIZE: This split cal king sized mattress is purpose-built for couples who want individual adjustable base control without sacrificing a full king footprint.
BEST SLEEP MATCH: Best for back and stomach sleepers who prefer a firm mattress for back sleepers. The minimal surface cushion keeps the spine straight rather than letting the hips sink.
BEST FOR: Ideal for sleepers who need consistent lumbar support, wake with lower back tension, or share a bed and want independent adjustable base options.
CONSTRUCTION SPECIFICATIONS: The SealyStability™ encased coil system lets each coil respond independently, so movement on one side doesn't carry to the other. The CoreSupport™ center adds reinforced support beneath the heaviest part of your body. StableEdge Pro™ holds the perimeter firm so the usable sleep surface runs fully edge to edge. A knit cover with MoistureProtect and Surface-Guard Technology wicks moisture and resists odors.
SETUP AND COMPATIBILITY: Arrives flat with white-glove in-home professional setup available. Compatible with adjustable bases, platform frames, and box springs. No tools required.
NOT A FIT FOR: Not the right match for side sleepers who need pressure relief at the hip and shoulder, or for anyone who prefers a plush or cushioned surface feel.
