Sleep up to 4x cooler*
If you sleep hot, you’ll like this. Our exclusive GelFlex Grid material is essentially incapable of retaining heat. It regulates your temperature through 1,400+ open air channels and maximizes breathability for comfortable sleep, year-round.
We don’t play around with temperature balance
When we talk about superior temperature regulation, we mean it. Our mattresses were tested against competitors in an independent study. The GelFlex Grid stays temperature neutral, so your body can find a perfect sleep temp and stay there. Not too hot, not too cold, no gimmicks.
Three levels of temperature balanced sleep
Each mattress collection builds upon our exclusive GelFlex Grid technology, offering additional ways to prevent hot sleep.

Frequently asked questions
Purple mattresses stay cool because they’re built around the GelFlex Grid—an open, breathable structure designed to let air flow freely where your body meets the bed.
Unlike traditional foam mattresses that can trap heat, the GelFlex Grid allows warm air to move away instead of building around you. As you shift and settle throughout the night, the GelFlex Grid flexes with you while keeping airflow consistent, helping your sleep surface feel cooler and more comfortable.
Cooling mattresses work best when cooling is engineered into the mattress itself, not just added on the surface. Many mattresses rely only on cooling covers or infused foams that may feel cool at first but can still trap heat over time.
Purple takes a different approach. Every Restore Hybrid mattress combines the breathable GelFlex Grid with responsive coils to promote airflow and help heat move away from your body. This design allows sleepers to sleep up to 4x cooler*—creating a more consistently cool and comfortable sleep experience throughout the night.
The coolest mattress for hot sleepers is one that doesn’t trap heat in the first place. Instead of surrounding your body with dense foam, it allows heat to move away, so your sleep surface stays cooler and more comfortable.
Purple mattresses are built with the GelFlex Grid, an open, breathable design that lets air flow freely across the entire sleep surface. By allowing heat to dissipate rather than build up, the GelFlex Grid helps create a cooler-feeling bed that stays comfortable throughout the night.
Specifically, the RestorePremier Hybrid mattress is Purple’s coolest mattress for hot sleepers. It sleeps 4x cooler* than the competition with 100% free airflow between CoolFlex Coils and 3” deep GelFlex Grid.

Purple partnered with SleepScore Labs, the world’s only sleep research organization, to quantify our patented sleep technology’s impact on sleep. Using validated, non-invasive technology, SleepScore Labs verified the GelFlex Grid’s ability to provide easier, better, transformative sleep.
SleepScore Labs tracked participants’ sleep on their original mattress for four weeks, then on a Purple mattress, either from the Essential collection or Restore Hybrid collection for six weeks. Sleep was measured using SleepScore Max technology and validated surveys for pain and comfort.
