Wish there was an air pressure seat
I am so looking forward to someone who can invent an seat that uses air pressure and may be a pump or co2 cartridge instead of adjustment cord and latches that corrode with seawater.
Wish htere was an air pressure seat
Admirable thought on the pressurized seat but i think we have a bit longer to wait !
that’s because they’re experienced
...and they know that relying on back support impairs the effectiveness of a paddle stroke. Some of us have been where grubfish is now and fortunately, received advice that worked.
Feathercraft
Feathercraft folding kayaks have a very comfortable compact inflatable seat with low lumbar placement-- separate valves for back and bottom with infinite adjustment via flexible tubes. I don't know if they sell the seats separately from the factory (not listed in their parts catalog anymore) though I have seen used ones occasionally on Ebay where they go for around $150. Since the seats are suspended from the frame longerons and cross-ribs one would have to build something within the cockpit of a hard-shell to attach the seat but that could probably be accomplished with PVC pipe.
Pakboats folding kayaks also have an inflatable seat ($110), though not as ergonomic as the FC model, it does have nice thigh support.
