ZINUS 12 Inch QUADCOOL Memory Foam Mattress - Cooling Comfort

Our review of the ZINUS 12 Inch QUADCOOL Memory Foam Mattress finds it best suited for hot sleepers who want medium-feel pressure relief without the fuss of innersprings. The single biggest reason to buy is its layered cooling system: a cool-to-touch knit cover, gel-infused memory foam with a ventilated 7-zone comfort system, and an Airflow Comfort Foam transition layer that work together to reduce heat build-up. For those who want a sealed-foam mattress that ships compactly and is certified for safer materials, this mattress delivers a straightforward, cooling sleep surface.

Key Features

• Cool-to-touch cover: The knit top feels cool on contact and helps reduce initial heat sensation when getting into bed.
• Gel-infused memory foam: Gel infusion adds localized cooling while the memory foam contours to relieve pressure across shoulders and hips.
• Ventilated 7-zone comfort: Zoned ventilation provides targeted support and pressure relief for different body areas to improve spinal alignment.
• Airflow Comfort Foam: The transition layer increases internal ventilation so the mattress breathes better over long sleep sessions.
• CertiPUR-US and OEKO-TEX: All foam layers are CertiPUR-US certified and the cover is OEKO-TEX certified, reducing exposure to harmful chemicals.
• Compact WonderBox shipping: The mattress arrives compressed in a smaller box, which reduces packaging and shipping impact.

Who It's For

The QUADCOOL is a good choice for back and side sleepers who prioritize cooling and pressure relief from an all-foam mattress. Hot sleepers and those who want a low-maintenance bed that arrives rolled and ready to expand will appreciate the ventilated layers and cool-to-touch cover.

It may be less suitable for people who prefer a very plush or a traditional innerspring bounce, or for sleepers who need a very firm surface; customer feedback on firmness ranges from medium to quite firm, so careful consideration of personal preference is advised.
