I’m a kayak fisherman with an sit-on-top Emotion fisherman kayak. I have a cheap seat and I have tried a $100.00 seat before which I took back. While I fish my lower back gets sore I’m sure a more expensive seat will make my butt comfortable but my back needs support, maybe its the way I sit but I usually shove something behind my lower back to act like a lumbar in a car seat for relief. I’m 6’0 tall 215 lbs thick athletic build. All the seats I look at don’t seem to have any kind of lower back support. I usually quit fishing because my back gets so tired so any kind of advice would help. Thanks for your answers.
