[cool][#0000ff]Getting the seats adjusted so they are both functional and comfortable seems to be one of the biggies for every new tube and tuber. [/#0000ff]

[#0000ff]The ODC 420 tends to let the top piece of foam slip down behind the bottom piece, if you do not have those two straps at the bottom backside snugged up good. Sounds like you have found that problem and may have it solved.[/#0000ff]

[#0000ff]Yes, I started the PVC backrest idea. It started out as the connection foundation for a prototype Bimini shade cover. That worked, but I did not use it that much. However, I left the crossbar in place since it raised the seat back and created more rigidity. TubeBabe also wanted one on hers and neither of us would take our tubes out without them now.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Here are a couple of pictures that show the basic design. You just measure the width inside the seat cover, and cut the width of the crossbar to fit...considering the size of the fittings, etc. The downside is that you have to cut a small hole in the top of the seat cover through which to shove the 1/2" PVC down through. You also have to take out the foam back piece and cut a V groove down each side to accomodate the PVC. A good sharp knife and a steady hand makes that a quick job. Put it back in, cinch up the straps, insert the PVC, and you are good to go.[/#0000ff]

[#0000ff]By the way, the next time I mess with that, I am going to raise it a bit and shove the cross piece through a piece of foam noodle before gluing in place. If I get the height right, it will hit me right about the neckline...providing a nice head rest for on the water naptime.[/#0000ff]
