Looking for gel seat cushion info

[Brentc]

I’ll try to keep this short. Eventually when we upgrade to our next spyder, thinking 2020 model, I want to get a Russell day long seat. Until then I would like to get something to “take the edge off” of the factory seat on our 2014 rts. Seat now is good for about an hour and half then gets uncomfortable for me and wife. I have an airhawk presently and it helps, but need to get something for my wife and she is thinking of a gel style cushion. Not wanting to modify existing seat, so probably not looking at an insert, but more of an on top the existing seat option.

Would appreciate any thoughts and ideas that others may have, and thanks as always!
