Thousands of open-air cells actively channel heat away. Cooler than traditional memory foam.
Proprietary grid reinforcement helps reduce motion transfer and eliminates the "jiggle" that other grid mattresses have.
Long-term support, built to last, and backed for life.
Inside the GelGrid™
GelGrid™ doesn't choose between comfort and cooling—it delivers both. Open cells flex to your body while heat escapes continuously.
Engineered Stability with Integra-Mesh™
We didn't just make a grid—we reinforced it. Integra-Mesh™ is woven into every GelGrid™ layer, eliminating the surface wobble that plagues other designs.
Flex Where You Need It. Stable Where You Don't
GelGrid™ isn't one-size-fits-all. It flexes at your shoulders and hips while supporting your spine. Every zone responds to YOU—not your partner's movement.
Cooling That Doesn't Wear Off
Traditional foams absorb body heat with nowhere for it to go. GelGrid™ channels stay open under pressure—so heat moves out, not into your sleep.

FORM's GelGrid™ technology improves pressure relief and response time, while the reinforced coil base delivers true spinal alignment. It's one of the best options on the market for sleepers who want cooling and support in one.
Dr. Mostafa Miata, M.D.

For patients who struggle with overheating or restless sleep, FORM's open-air GelGrid™ design makes a noticeable difference. It provides pressure relief without the heat buildup common in traditional memory foam.
Talalay latex is naturally buoyant and breathable, adding a lifted feel and faster response.
Shoppers who want the most premium materials and the fastest response feel in the lineup.
A grid mattress uses an open-cell grid layer (instead of thick memory foam on top) to provide pressure relief and airflow. FORM uses GelGrid™ for cooling and adaptive relief.
FORM reinforces the grid with Integra-Mesh™, a proprietary system integrated into GelGrid™ to help prevent buckling and reduce the “jiggle” some people feel on other grid mattresses.
FORM is designed to sleep cooler than traditional foam mattresses because GelGrid™ has open-air channels that help heat escape.
Yes. Integra-Mesh™ reinforces the grid and reduces ripple, which can minimize partner disturbance.
