So I have not put a 300-mile ride on this seat yet. But, or butt, we did a 150-mile ride this weekend and I am very pleased. More importantly, my wife (pillion) was extremely pleased. The seat gave me a great position forward, and lower while riding. Very comfortable. My wife says she could do a weekend on the pillion. I think after some wearing in she will be more pleased. I took it out today for a 50-mile solo ride and I am very happy with the comfort, seating position, and the overall fit. I am recommending a Seth Laam seat at this point. For what it is worth to all.
