cushion seats?

[cool][#0000ff]I had thought of the spray foam a couple of times too. However, as you guess, it is not tough enough to withstand some sitting and flexing. It disintegrates. It is designed to shoot into a crack or crevice and then be left alone. It is also nasty stuff, with formaldehyde fumes. You could embalm yourself.[/#0000ff]

[#0000ff]I am still looking for a firm but soft closed cell foam that could be easily carried and would not wear out easy or soak up water. So far I haven't found the ideal solution.[/#0000ff]
