Overview
Serta Perfect Sleeper Dutch Iris Firm Mattress 12" Cal King
The Serta Perfect Sleeper Dutch Iris Firm Mattress 12" is a hybrid mattress built for back and stomach sleepers who want firm, structured support without sacrificing temperature comfort. The 3 Zoned Coil Design delivers targeted lift where your lumbar and hips need it most, so you stop waking up stiff and twisted. Cool Twist Gel Memory Foam sits above the coils and draws heat away from your body through the night, giving firm-sleeper comfort without the trapped warmth that plagues traditional innerspring builds. If you have been sleeping on something that goes soft in the middle or runs hot, this is a straightforward fix. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to every competing option so you can feel the difference for yourself.
COMFORT AND FEEL: Firm feel with cool, contouring memory foam and zoned coil support underneath.
SIZE: This Cal King sized mattress is the right fit for tall couples or solo sleepers who want maximum room to stretch out.
BEST SLEEP MATCH: Best for back and stomach sleepers who need a firm mattress for back sleepers to keep the spine neutral without sinking. The firm feel prevents the hips from dropping, so your lower back stays in line all night.
BEST FOR: Ideal for sleepers who run warm, need consistent lumbar support, or wake up stiff from a mattress that has lost its shape.
CONSTRUCTION SPECIFICATIONS: The Cool Twist Gel Memory Foam layer pulls heat away from your body and contours to your shape. Beneath it, a Cool Twist Gel Foam layer promotes airflow for additional heat dissipation. The 850-coil 3 Zoned Coil Design focuses targeted support on your lower back and hips. Foam encasement reinforces the edges so the full sleep surface stays firm and usable.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup available. Compatible with adjustable bases, platform frames, and box springs. No tools required.
NOT A FIT FOR: Not the right choice for side sleepers who need deep pressure relief at the shoulder and hip. Sleepers who prefer a plush or pillow-top feel will likely find this too firm.
