Hello recumbent users.

Greetings from Portugal.
Last year I purchased a used recumbent bike and entered the recumbent world.
I had to change the seat padding since it was not in the best condition.
I'm a DIY type of guy so I made the padding myself.
My seat is the recurved fiberglass type and I used a large piece of spaghetti vinyl loop mat, (since I have seen it before). I doubled it at the bottom for extra cushioning and covered it with a polyester mesh fabric (sandwich spacer cloth kind).
It ventilates, it drains, it protects my bottom... but in long distances (touring) I need something softer in my coccyx area. (I'm the thin type of guy and don't have much self-cushioning)
Did someone try the latex seat pads? (like the ones used in rowing machines)
Any other suggestions are appreciated
Ride safe
