Need a better seat for my sit on top

I have a 12’ ocean kayak scrambler. I like it and have had it for years.



I would like to get a better seat than the typical strapped in seat for kayaks. I am thinking something with a pretty ridgid back rest.



I bought an inexpensive boat seat, the kind that mounts on a steel swivel mount to a flat surface.



Because it raised the center gravity so high, it is way to tipsy for this 260 pound old fellow.



Anybody have any suggestions.

SOT’s are what they do.
