The inflatable Cumberland seat... once again

Just wondering if anyone has used the Creek Company or Outcast inflatable seat for a Cumberland tube?   Went through 5 pages of related threads but none really explicitly saying they've used those inflatable seats in a Cumberland.  Not looking for a softer seat looking to have something that can pack down for travel.  I fish in a pontoon all day.  That Cumberland seat is the softer solution!  

VegasFishing went through dimension of his ODC420 in is video ([You must be registered and logged in to see this link.]) which are pretty much the same as the Cumberland. So I think that will work.  Waiting for my buddy to get back in town to measure his FishCat or I may try to see if they fit after we go out fishing sometime.

campbellrus ordered some for his Cumberlamd but I haven't found a post with his results ([You must be registered and logged in to see this link.])

Just looking for reviews of fit and finish and pros and cons of those inflatable seats in a Cumberland.

An Outcast seat and back fit perfect.  It will prove useful when the need to break down 3 sets of tubes, waders, fly rods and other gear for a long trip in a Chevy Tahoe arises again.  That Cumberland is a clunker in that respect.

Will keep the foam cushions installed most of the time when I meet up with buddies for local fishing because it's quicker to get on the water but, I will either chamfer the front edge or get a waterproof orthopedic comfort seat as a topper. The backside didn't hurt as much as the hamstring area.  Ironically, my hard plastic pontoon seat gives me no trouble at all.  I think the reason is that it's ergometrically molded instead of flat like the foam.

Well that is great to know thanks for sharing now the info is here and others can benefit from it as well. Thanks for sharing guys check it out.

I had MAJOR butt pain problems when I first bought my Cumberland (1st time float tubing, ever). The surface was too hard and I couldn't fish for more than a couple of hours. I tried a gel pad, foam, etc. but nothing worked. I even changed seating posture several times and nothing helped. I was ready to give up until the pain magically stopped and I didn't even notice. Maybe I just needed extra time to adjust; who knows! I think I'm gonna buy the Outcast seat and back now just as a backup, in case pains comes back. Good to know it fits!
