The backrest has a little wrinkle in it. Have to have it stretches a little more. But my vision for the 3 cushion seat worked great. With the "platform" to step into the boat rather than on the upholstery worked out great.
They stapled it flat and not for the curve. Imagine it was perfect laid out flat. Take the boat when they redo it. I had to redo my front curved backrests like 3x to get it perfect just b/c the tiniest bit of flex will cause wrinkles.
