One of the most comfortable (well 6) are the big game, with swivel seats. The seat and back are sprung with bungy cord. Have lasted over 4 years now, but I do take them in during off season. A number of others are all two man with expanded metal seats. I use a boat "throw" type cusion (camo pattern) they last the best because of the UV Inhibitor for boating use, they are rather thick but extremely comfortable. They have arm loops for flotation, easy to sling over shoulder.
