Im looking online for a seat with great lower back support. Probably a taller seat back. Im guessing the back band that came with my kit will not give me the support my lower back needs. My question is I see a lot of Sit on top seats online. Wouldnt you be able to attach one of these "sit on top" seats inside the cockpit of a chesapeake 17 as long as the dimensions fit my kayak??? Thank you for any help!!!
