Serta Perfect Sleeper Dutch Iris Firm Mattress 12″

Serta Perfect Sleeper Dutch Iris Firm Mattress 12″ Queen

The Serta Perfect Sleeper Dutch Iris Firm Mattress 12″ is a hybrid mattress built for back and stomach sleepers who need real lumbar support without waking up stiff. If a firm mattress for back pain relief is what brought you here, this is the one worth lying down on. The coil system does the heavy lifting, keeping your spine neutral through the night, while the gel memory foam layers add just enough give so firm never feels punishing. Stop by any Mancini’s Sleepworld location and our sleep specialists will put this one next to every option in its class so you can feel exactly what three zones of support means for your lower back.

COMFORT AND FEEL: Firm feel with cool-contouring memory foam and zoned coil support underneath.

SIZE: This queen sized mattress is ideal for solo sleepers or couples who want a firm, back-supportive sleep surface with room to move.

BEST SLEEP MATCH: Back and stomach sleepers will feel right at home on this firm hybrid. The coils keep hips and lumbar lifted, making it a reliable firm mattress for back sleepers who’ve given up on softer options.

BEST FOR: Ideal for sleepers who need firm lumbar support, run warm at night, or have been waking up with lower back tension.

CONSTRUCTION SPECIFICATIONS: Cool Twist Gel Memory Foam™ pulls heat away from the body while contouring closely to your shape. Below it, a Cool Twist Gel Foam layer keeps airflow moving through the night. The 850-coil 3 Zoned Coil Design delivers targeted support at the hips and lower back. A Balanced Support Pad and Best Edge Foam Encasement round out the build, keeping the perimeter firm and usable.

SETUP AND COMPATIBILITY: Compatible with adjustable bases, platform frames, and box springs. Delivered flat with in-home professional setup available, no tools needed.

NOT A FIT FOR: Side sleepers or those with shoulder pressure sensitivity will likely find this firmness too unyielding for comfortable nightly rest.
