Zinus 12 Inch QUADCOOL Memory Foam Mattress, Queen, Cool to Touch Soft Knit Cover, Cooling Gel Infusion, CertiPUR-US Certified Review (2026)

Who this mattress fits

This queen mattress from Zinus is built for shoppers who like the pressure relief of memory foam but worry about foam sleeping warm. It suits side and back sleepers who want a medium feel bed that arrives compressed in a box, since Zinus ships this model rolled up for easier delivery and setup through a standard doorway. It is less suited to people who specifically want a coil or hybrid mattress, since this is still an all-foam build, and to sleepers who need a firm surface, since memory foam contours rather than pushes back. Couples who run different temperatures may find the cooling layer helps the hotter sleeper more than it changes the overall firmness for the cooler one, since the cooling features address heat rather than support.

How the QUADCOOL layers work

The name QUADCOOL points to four layers stacked to manage heat, starting with a cool to touch knit cover on top of gel-infused memory foam and a ventilated zone layer underneath. The gel infusion is designed to pull heat away from the body as you settle in, while the knit cover itself feels cool at first contact, the way a jersey sheet does. Zinus builds all the foam layers to CertiPUR-US certification, which means the foam is tested for content, emissions and durability by an independent program. The base layer supports the softer comfort foam above it, and Zinus rates the queen size to support up to 500 pounds. The mattress needs time to expand fully after unboxing, and it can take up to 72 hours to reach its full loft and firmness.

Setup, daily use and care

Expect the mattress to arrive rolled and vacuum sealed in a box, which two people can usually carry into a bedroom without much trouble even though a full mattress is heavy on its own. Once unrolled on a solid foundation or slatted base, it needs to air out for a day or two before the factory smell fully clears, which is typical for boxed foam mattresses. Rotating the mattress head to foot every few months can help it wear evenly, since foam beds do not flip like older innerspring models. For care, a mattress protector keeps the knit cover clean and helps preserve the cooling effect, since spills or heavy soiling can affect how the top layer breathes over time. Spot clean any stains with mild soap and water rather than soaking the foam.

Trade-offs against other cooling mattresses

Compared with the Zinus Green Tea Cooling Gel model, the QUADCOOL line adds more cooling layers but has less of a track record since it is a newer release, so shoppers who want a longer history of owner feedback may lean toward the Green Tea version instead. Against a coil hybrid mattress, this bed still traps more heat at its core because it has no coil layer to promote airflow through the middle of the mattress, even with the gel and knit cover doing their job near the surface. Shoppers who sleep especially hot, share a bed with someone who runs warm, or live somewhere without air conditioning may want to pair this mattress with cooling sheets or a mattress topper rather than expect the foam alone to solve the problem.

Bottom line

The Zinus QUADCOOL queen mattress earns strong marks for stacking multiple cooling features into a CertiPUR-US certified foam bed at a reasonable price point for the category, which lines up with our score of 8.2 out of 10. It fits shoppers who want memory foam comfort with a cooler feel than a standard all-foam mattress, and who are comfortable with the setup and off-gassing process that comes with any boxed mattress. Buyers who need maximum airflow, prefer a bouncier coil feel, or want a mattress with years of reviews behind it should look at a hybrid design or the longer-running Green Tea line instead.
