Zero Gravity Seats.

 "Zero-gravity" seats on aircraft are not actually zero gravity, but rather, they are designed to reduce the effects of turbulence and provide a more comfortable flight.

They are typically reclined at an angle that minimizes the pressure on the passengers' spine and provides a feeling of weightlessness.

This is achieved by reducing the pressure on the seat and allowing the passenger to float slightly, reducing the pressure on their back, and reducing the feeling of turbulence.

It's important to note that these seats are not a replacement for turbulence-smoothing technology, and that turbulence is still felt during flight.

However, the seats can help to reduce the discomfort experienced by passengers during turbulence, making the flight more comfortable.

The Nuage (Cloud) seat as they are known in the industry offers the industry's first zero-gravity seating position for reduced lower back pressure, optimized weight distribution and improved circulation for effortless comfort.
