You could buy some leathrette seatcovers with added foams in it. Para mas malambo upuan and sandalan. Modifying your suspension settings would be helpful, but are you willing to compensate the cargo capacity it can carry? Taking a leaf spring out or inverting it will definitely improve ride comfort but cargo-wise will be limited to half of it.

Opting for a more street friendly tire with softer sidewalls can be helpful. But this will cost you more.

One more note in hand, never ever match gas filled shock absorbers with leaf springs. This will tend to have a harsher ride.
