Has anyone recovered a vintage seat? I have used the light colored, upholstery foam padding you find at a crafts store but I am not satisfied with the cushioning - it seems too soft. Does anyone have a suggestion on where to look for a firmer padding?

The Bunch O Bikes site has a detailed DIY on seat recovering which is a very good step-by-step instruction. It shows the kind of foam that I'd like to replace with something firmer.

Thanks for any suggestions.
