While I do have a backrest, my King Big Boy seat doesn't have the slot for one. When looking for a backrest, a lot of the ones I saw said they're not for use with solo seats, as that is how I'm set up.
Additionally, the seats position, for some reason, puts me in a different angle and my joints were hurting me trying out the King. The regular Big Boy with the backrest works well for me.
I do have pullback risers as well, love 'em, wouldn't do without them.
As you know, everybody's different and it's a hit or miss until you find what works well for each individual. What I'm looking for, is spot on for moi!
