Question: I've seen reviewers saying that the straps aren't long enough for the newer, molded canoe seats.  How long are they exactly?
Document: The straps are not nearly long enough for a canoe with molded seats. I wish they would redesign them so they can, then it would be a keeper. Had to return it.
The hinges are plastic, so I do question how long those will last. I'm a pretty big fellow and yet this seat did not seem too small.If you have an older canoe with old style seats, this chair should work for you. Otherwise, if you have a newer canoe with molded seats don't waste your time.
This product is not designed for newer canoes with the molded bench seats. The straps that hold the chair on the canoe seat are very short and will only fit around an old fashion cane canoe seat. Even then, I question how well it will stay in place because you can only get the straps so tight. It's just a rather lame design.
I'm in the process of restoring a very old canoe and these seats work fantastically. Very easy to adjust and they simply strap onto the existing wicker seating with velcro straps. I know that sounds like a cheap secure job, but the straps are long and strong enough to handle it. I highly recommend these to anyone who just wants a little back support for their canoes. Fisherman, these also have enough give for when you really need to dig back in your pull.
Was hoping to put this on my canoe but the straps aren't long enough to reach around the seat! As it's advertized as a canoe seat I was hoping it would fit and it didn't!
Saves my back on canoe trips and fits w/my canoe's molded seats.
This GCI Sit Backer seems to be well enough made but it is not as comfortable as some would have you believe. I had to run extra straps from the top of the back of the seat directly to the wooden canoe seat because the GCI would flex too far back to be comfortable. I did tighten the side straps that are on the unit down, but they did not stiffen the seat up enough.
I was not overly impressed with the quality of the seat for the price. The straps are also very short and would not fit on the seat of the plastic canoe I purchased it for. I returned it as it did not seem high enough quality for me to mess with adding strap material to get to fit. I think a quality sit on top kayak seat and some pad eyes riveted on will work better and be more comfortable for my plastic canoe.
The pocket on the back was handy for keeping a few things (sunscreen, map, etc.) close.The seats fit well in both my smaller 12 ft canoe with bench seats and the 16 ft wenonah that we rented with canvas webbed seats. They may not have worked as well with the molded seats on the old town that our friends brought along.Overall, I definitely recommend these to anyone who canoes frequently.
Let me start out by saying I'm not the type of person who says that a product is either awesome or sucks. I tend to be realistic about my evaluations, and most of the stuff I buy (whether on Amazon or at other places) gets three stars. Furthermore, I don't evaluate most of the stuff I buy, because it's just not worth my time. But with that said...I've been an avid canoer/kayaker for about 20 years.
Answer: yes
