I built this pillow because every morning my blankets ended up on the floor. I was always kicking my legs and readjusting my body all night. Being a mechanical prototype guy by trade, I wanted to figure out why.

At my company, GizzMoVest, we design and build custom cases here in the USA. This pillow project took me about two years to finish. Along the way, I bought a lot of “side sleeper” pillows, but none of them worked.

So, I set out to find a solution. I broke the problem down further. I bought a FLIR infrared camera and started taking heat images. After two years of testing materials, measuring pressure points, and working with foam engineers, what I saw was clear: when my hands or legs touched, surface temperature spiked. More surface contact = more BTU = more heat. That explained the constant movement at night — my brain was kicking in to cool my body.

Separating the legs was the next challenge. Sure, pillows could do that, but most fabrics have slow air movement. Slow air = trapped heat. I needed separation and airflow. That’s where my skills came in: testing, retesting, and looking at every material I could find.

Finally, I discovered a material with the right balance: thickness, airflow, and light weight. Then came the core. Standard head pillow foam was too stiff, so I worked with a foam supplier. They explained it’s all about pounds per square inch. I measured the actual weight pressure between my legs, and they developed a very lightweight memory foam that fit the need.

Here’s how it works:
• Your body already has a perfect cooling system. Standing, with legs apart, your skin stays cool.
• Lying on your side, legs touch, airflow is cut off, heat builds. Your brain senses overheating and makes you move — even kicking blankets off.
• Back sleepers don’t have this issue since their legs stay apart.

Our pillow solves it. The thick mesh outer cover allows steady airflow, keeping legs cool while also keeping skin off the foam. The lightweight memory foam core forms perfectly to your legs for comfort.

The “Side Sleeper” pillow is designed to rest between ankles and knees. It keeps legs level, reduces side pressure on knees, and keeps airflow moving all night.

The result: cooler legs less movement, deeper sleep.
