After doing my research last week, I started to choose materials and methods for prototyping based on my vision.
My idea is that there’s an air cushion and a hard ball, air cushion on top, ball on bottom, something like this:

The picture on the upper left shows a round air cushion with some balls in it. When the air cushion collapses, the balls in it hit your butt.
The picture on the lower right means a square air cushion with holes in the middle and balls in the holes.
I found that both schemes included “air cushions”, so I searched Taobao for products related to air cushions.
Finally, I found this:

A cushion to prevent bedsores, it was exactly what I had imagined, so I looked at the size of the balls and bought some 4cm in diameter.

Final production process and finished product:

The finished product is a cardboard bottom, and then the ball is in the pit, so when the cushion is out of air, you’re on top of the ball.
