I did mine without the plastic, but with the help of my wife. After tugging the vinyl onto the seat and frame, I left one edge (front edge or back edge, I can't remember, but I don't think that it matters) just hanging barely over the edge of the table. Here's where my wife really comes in. While I lay on my back under the table, she laid down over the seat starting at one end. She would hold the vinyl tight while I would put in a few of the "c" clips then we would move down to the next section. Once finished with one side-make sure to keep a nice even line with the vinyl-we switched to the other side and did it, then the two ends. I think it came out looking nice.
