Not the back of the boat...MY Back! I did a lot of reviewing and finally decided to break down and get something better for my poorly vertebraes. If youll remember my wonderful vacation in arkansas...I went this past weekend on one of those 40 year old seats and it likened to kill me. FIgured Id better invest in something better. I like this one so far..Made in USA..big plus. Tempress Navistyle. Lots of good reviews. Ill know how an 8 hour day goes in it come Saturday.
