Kayak seat with lumbar support

I just ordered this and am hoping the back support is what's claimed.

I used the "Make an offer" function and $70 was accepted (I asked them if they would like that advertised and they said "we can always use more business"). With tax and shipping it totaled $92+ to the door.

I have one of those seats from 6 or 7 years ago. It fits great on some kayaks but others the rod holder tubes causes issues. It depends on the height of the molded seat back curve.

My best expectation is that those holders will work for accessories (club, snare, net, etc...) if they happen to do ok for rods that would be a bonus.

How do/did you find the seat for back support? In my T160 I kept moving the back support lower and lower as the day progressed... and it wasn't helping after about 6 hours.
