[cool][#0000ff]I have had tubes with both inflated and foam seats. One of the advantages of the inflated seats is that they completely fill the seat pockets. Rock solid. No folding in at all. The foam seats SEEM to fill the pockets but there is still SOME play no matter how tight they fit. [/#0000ff]

[#0000ff]It does not take much when you sit down to allow the sides to creep in on you. Extra inflation might help but not it it overinflates the air chambers and causes damage. Adding a piece of plexiglass or even stiff plywood (doesn't last) will increase rigidity. Slide it under the foam.[/#0000ff]

[#0000ff]Some of us are using molded plastic chair seats to create the rigidity and the seat width we need for comfort. The firm chair back helps too, especially if you are tall or have a back problem.[/#0000ff]
