Lifetime kayak seat upgrade...say NOOOOO to stadium seat! 

Yes. Much more stable than with the stadium seat. I can reach into the water to catch and release fish as well as rock the boat hard with no concern. I did experience lower back pain when I got out of the boat (about 4 hrs fishing), but none while in it. I also took a shorter trip (about 2 hrs) and very little pain when I got out. The padding on the seat is excellent, so I think the pain may be related to the angle of the seat...so I may have to mess with that a bit.
