I just bought one of these because it was roughly half the price of the OEM backrest (Yes, I'm cheap) and although the install was pretty straightforward (only issue was 1 screw was too short) and I like the way it looks, I almost took and it off and returned it because it was horribly uncomfortable on my back. I played with it for 1/2 hour adjusting the position but soon realized that the problem wasn't with the height, size or position but with the stiff padding that they use inside. Luckily, they provide a full length zipper so I pulled the padding out and made my own padding from some thin foam that I had laying around and it made all the difference in the world.

Not sure why they chose that particular type of stiff foam but it is not like any foam I have seen for a seat or cushion.

So, if you buy one of these, you might consider removing the padding and stuffing it with something softer before you give up on it.
