What Our Customers Are Saying
A Seat Cushion Built for People Who Fly
Two hours in, your tailbone screams. By hour four, your legs go numb. By landing, you're hobbling off like you aged 20 years.
It's not you. It's the seat.
CoolCel was built to fix that.
The HexFlex Gel Grid™ redistributes pressure across hundreds of flex points. Your hips stay level, your spine stays aligned—no slumping by hour three.
Unlike foam that flattens and traps heat, CoolCel keeps you cool and supported. Even on 14-hour flights.
Improve Posture & Increase Blood Flow
Airline seats weren't designed for your body—they were designed to cram more passengers per row. Your hips sink, your thighs compress, and blood flow gets restricted. That's why your legs go numb and you're still stiff hours after landing.
CoolCel fixes this by keeping your hips elevated and reducing thigh compression, so blood circulates naturally. You stay aligned and comfortable—even on back-to-back red-eyes.
Built to Go With You Wherever
CoolCel works on any seat: economy, business class, rental cars, hotel desk chairs, even your home office between trips. The non-slip base grips tight—no sliding mid-flight or constant readjusting when you shift positions.
The honeycomb gel grid won't flatten like foam cushions that die after a few trips. It maintains its shape through hundreds of flights, and the removable cover is machine-washable so it stays fresh no matter how many time zones you cross.

Works On Every Type Of Pain
-
Tailbone Pain
The honeycomb gel collapses under your tailbone to eliminate direct pressure on your coccyx. No more constant ache or numbness at the base of your spine—even on 10-hour flights.
-
Sciatica & Shooting Leg Pain
Maintains proper spinal alignment and eliminates pressure hot spots that trigger sciatic nerve pain. No more shooting pain down your leg or that burning sensation in your hip.
-
Lower Back Stiffness
Distributes your weight evenly across the entire cushion so your hips don't collapse into the seat. No more that achy stiffness in your lower back hours after you land.
