Hey there.
The seat is made out of a skateboard and it was unconfortable, in fact.
The problem was it's angle, wich I have already improved, and not the fact that it's made out of plywood and without cushion.
Now it's almost horizontal and quite alright to ride.
I meant for using this build on the RRB Build Off, but it happened almost overnight, and I did'nt document it.
Thanks and keep it up.
