Is Perfect Sleep Really Possible? We Found the Answer Under $1,200

The perfect mattress means something different to everyone. Some people need firm support for back pain. Others want plush comfort for side sleeping. Many just want to stop waking up hot and restless.

If you know you need targeted support, cooling technology, and hotel-quality comfort without the luxury price tag, the Serta Perfect Sleeper Cobalt Calm might be exactly what you're looking for. It's engineered with 3-zone targeted comfort and pressure-relieving memory foam that actually adapts to your body.

WHO IS THIS MATTRESS FOR?

The Cobalt Calm solves specific sleep problems for specific sleepers:

Side sleepers needing pressure relief at shoulders and hips
Back sleepers wanting proper spinal alignment
Hot sleepers craving cool, breathable comfort
Couples seeking motion isolation so you don't wake each other up

If you've been struggling with any of these issues, this innerspring mattress might be your solution.

WHAT MAKES THE COBALT CALM DIFFERENT?

3-ZONE COIL DESIGN
Most mattresses treat your whole body the same. Not this one. The 850-coil density system delivers three targeted support zones—firm support exactly where your lower back and hips need it, with cushioning where you don't.

COOL TWIST GEL MEMORY FOAM
Cooling gel is swirled directly into breathable memory foam to promote airflow and heat dissipation. You get the contouring comfort of memory foam without sleeping hot.

COOL FEEL FABRIC
The moment you lie down, you'll feel the difference. The cool-to-the-touch cover sensation comes from plant-derived technology that's 53% biobased and USDA Biopreferred certified.

ANTIMICROBIAL PROTECTION
Keeps your mattress fresh and clean from odor-causing bacteria. This protects the mattress itself for years of better sleep.

THE INSIDER INFO ON PRICING
