My idea is to use 4" foam for bench cushions for a dinette. The other purpose of these cushions are to be a mattress when the table is lowered in place. My wife needs a EXTRA FIRM mattress due to her back issues. I have checked out mattress toppers but the ones I find do not seem to be firm enough. I have about decided to go to a furniture upholstery company and see what they can do for me. Has anyone dealt with this or have any ideas?
Thanks,
Earnest
