Re: 17' Memory Foam Topper
Take some cardboard or poster paper and lay it out short of the wall. "Eyeball" it as you free hand with a pencil, trying to match the curve. Cut with scissors. Then push the "eyeballed" curve into the wall, and make small reshaping cuts with your scissors until it fits well. You'll do that with 2 or 3 pieces across the back. Tape those together to make your pattern.
The foam cuts very nicely with an electric knife, following your pattern
