Sometimes parts break. Pictured below is the seat from my Wilderness Systems Commander 140. Moving back and forth from the Captain's Perch to the seat I didn't pay enough attention and a couple of times flopped down on the seat back instead of the seat and it eventually took its toll. I blame myself. When you don't pay attention and get in a hurry, stuff can break. My Commander doesn't qualify for warranty and I didn't see much in the way of tutorials of replacing a broken seat back so I figured, what the heck. I ordered the parts from harmonygear.com and the next day it was sitting on my door step. I ordered the seat back and the cover for it. Total with shipping was less than $25. The back offered as a replacement is bigger which I thought was a nice bonus. To do this, reusing hardware you'll need a flat head screwdriver and a Phillips head screwdriver. That's it.

The first thing you need to do is get the seat back adjustment straps loose. On the front of the seat near the corners are two Phillips head bolts. They are holding the straps in place. They will have a washer on each side and a lock nut. Remove and save these parts.

Now you have the seat back loosened from the front and if it's broken, it's completely loose. Now you need to pull the straps through the back of the rest. You will be removing the adjustment strap and the bungee. Hang on to these as well.

Tighten the straps a bit and attach the bungees and voila! You did it.
