Unfortunately, the picture shows 3 screws for the seat rest for each side. Mine came with 2 and one side was not aligned, so I had to drill a hole to secure it. For such a simple piece of equipment, you would think it would be manufactured correctly. Now I understand the discount. Let's see how it performs on the water. Also, for such a small addition, wouldn't it be nice to include mounting screws and simple instructions, not that I need any!! I have yet to use this seat but anticipating it will be everything I paid for.
