Overview

Serta Perfect Sleeper Dutch Iris Firm Mattress 12" · Twin

The Serta Perfect Sleeper Dutch Iris Firm Mattress 12" is a hybrid mattress built for back and stomach sleepers who want a firm mattress for back pain relief without sacrificing surface comfort. Twelve inches of structured support sits beneath a Cool Twist Gel Memory Foam comfort layer that contours closely while drawing heat away from the body. The result is a surface that holds you in place rather than letting you sink, so you wake up feeling level instead of folded. If you want to feel the Dutch Iris next to every competing firm hybrid in person, any Mancini's Sleepworld sleep specialist will be happy to walk you through the comparison side by side.

COMFORT AND FEEL: Firm feel with close gel-foam contouring and progressive coil push-back underfoot.

SIZE: This twin sized mattress is sized for solo sleepers, children's rooms, and compact guest spaces where every inch counts.

BEST SLEEP MATCH: Back and stomach sleepers will find this firm mattress for back sleepers keeps the spine level and the hips from dipping, reducing the lower back tension that builds overnight.

BEST FOR: Ideal for sleepers who run warm, need steady lumbar support, or wake up stiff from a mattress that lets the midsection sag.

CONSTRUCTION SPECIFICATIONS: The Cool Twist Gel Memory Foam™ pulls heat away as it conforms to your body. Beneath it, a Cool Twist Gel Foam layer keeps air moving through the comfort zone. An 850-coil 3 Zoned Coil System delivers firm, targeted push-back under the lower back and hips. A Balanced Support Pad and Best Edge Foam Encasement hold the perimeter firm.

SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup available. Works with adjustable bases, platform frames, and box springs. No tools required for setup.

NOT A FIT FOR: Sleepers who prefer a plush or pressure-cradling surface may find this firmness level too resistant. Not the right choice if you need significant shoulder cushioning.
