I have used mine one season. I bought it after losing the seat that came with my Coho (thermarest stadium seat). It is very comfortable and I can adjust the amount of air while paddling to lower my center of gravity if the going gets rough. The seat eliminates the problem of legs falling asleep. I can paddle all day with comfort. Having said the above, I must add, the seat does not offer the firmness needed for a proper fit for bracing, rolling, etc. I am currently making a carved seat from minicell to get the solid fit I would like, but for pure comfort the Thermarest kayak seat cant be beat.
