airseat like this ?

he people,

on unicycling.org I’ve found an indroduction into building a air seat.

Now I’m thinking how I can lay the tube on the seat…on the picture is on the seat-back in the middle a big part where isn’t any tube. Is it then enough air for a comfortable sitting on the seat ?

I hope someone know what I mean and can help me to putting the tube on the right position…

thank you
greetings from germany
