Overview
Serta Perfect Sleeper Dutch Iris Firm Mattress 12" · Twin XL
The Serta Perfect Sleeper Dutch Iris Firm Mattress 12" is a hybrid mattress built for back and stomach sleepers who need reliable spinal support and wake up warmer than they'd like. This firm mattress for back pain relief pairs a structured coil foundation with active cooling comfort layers, so you're not trading one problem for another. The result is a mattress that holds its shape through the night and lets you move without sinking. Stop by any Mancini's Sleepworld location and our sleep specialists can put this directly next to other firmness options so you feel the difference before you commit.
COMFORT AND FEEL: Firm feel with cool, contouring memory foam and steady coil support underneath.
SIZE: This Twin XL sized mattress is a natural fit for taller solo sleepers, college students, or guest rooms that need a compact, supportive option.
BEST SLEEP MATCH: Back and stomach sleepers will find this firm hybrid keeps the hips lifted and the lumbar where it belongs, so you stop waking up stiff.
BEST FOR: Ideal for sleepers who run warm at night, need lower back and hip support, or tend to wake up achy from a mattress that has lost its structure.
CONSTRUCTION SPECIFICATIONS: The Cool Twist Gel Memory Foam draws heat away from the body while contouring closely to your shape. Beneath it, a Cool Twist Gel Foam layer promotes airflow and helps dissipate warmth before it builds. The 850-coil 3 Zoned Coil Design delivers targeted support under the lower back and hips. A foam encasement along the perimeter keeps the edges sturdy.
SETUP AND COMPATIBILITY: This mattress is compatible with an adjustable base, platform frame, or box spring. It arrives flat and is ready for professional in-home setup by the Mancini's Sleepworld delivery team.
NOT A FIT FOR: Side sleepers who need deep pressure relief at the shoulder, or anyone who prefers a plush, conforming feel.
