Hi dvto2,
I would suggest caution in dealing with Foam Factory (AKA Foam by Mail or FBM). You can read more about them in post #2 here and in post #2 here.
Post #2 here has links to the forum lists that include the better options and possibilities I’m aware of that are closest to you. You may need to call them to find out the specifics of any toppers they sell.
