Support & Cooling

5 ZoneResponse Design

The 5 zones provide maximum firm support preventing lower back from arching for stomach sleepers. Enhanced support beneath lumbar region maintains proper spinal alignment while firm surface keeps body on even plane without excessive sinking.

Advanced Cooling Technology

CoolFeel Pro cool-to-touch fabric works with breathable latex foam to dissipate heat. PillowSoft Aire promotes airflow through rippling design. The firm surface prevents deep sinking that traps heat, maintaining comfortable temperature throughout the night.

Care Instructions

Use mattress protector to guard against stains. Rotate head-to-foot every three to six months. Avoid applying liquids directly to the mattress. Allow new mattress to air out for 24-48 hours after unboxing.
