Home made banana seat?

[fuzzwardo]

Any advice for making a banana seat to fit an adult bike? I saw some where that an old skateboard could be used as the base but can't remember where I saw it. Is this a reasonable idea? Then what to use for the foam?

Run a search for Ichi seat on here, you will see some examples.
Or just buy one from site sponsor Ichi Bike...
