This new self inflating kayak seat puts you on a cushion of air that gives the paddler incredible long range comfort and support heretofore unheard of in the sport. The bottom portion of the backrest has a durable self-inflating twist-valve. This valve lets you micro adjust the level of padding you''re sitting on and it''s conveniently placed at the rear of the seat for easy access. We've designed the lower pad with a wider base, virtually eliminating any pressure points. The maximum inflation of the seat bottom can be as much as 1.5'' giving the paddler incredible long rang comfort.
