Ok so I have a bus coming in with some generic basic bucket seats. I have to replace all the foam bottom cushions and I’m trying to figure out the best and most economical way to do these seat bottoms. They are just a wedge , how do I create that wedge easily. This is a church bus for a small church with a small budget. They will pay whatever the bill is, but I’d really like to keep it as low as possible. Also the backs are in better shape. But there is one that I will have to completely redo, any advice on that would be great as well. But the bottoms are the bigger deal there are 14 of them to do! Thanks so much I’m advance!!
