Replacing a Kayak Seat?

In a recent discussion regarding kayak selection someone commented that the seat should not enter into the consideration since it could so easily be replaced. Now I’m familiar with various add-on seat pads and the foam outfitting of cockpits, but are there more options that I am unaware of? What else can be done? Does anyone for example fiberglass a custom seat? Thanks.

One option is to cut out the stock seat
