I am planning to design this air mattress. Here is the picture that I want to model:
First thing that I was thinking was creating this individual cell (the puffy cell unit) from the mattress.
This is where I met an obstacle. My thought process tells me to start with a cube and refine it. It didn't quite work out and I used circle but couldn't process it to look like a cell. I am stuck for several hours. Is there a good tips or resources to come up with the cell design?
