If a ‘standard’ headboard calls for a one-inch medium-density polyurethane foam, could the Dunlop foam work as a substitute?

The craft of (RE)upholstery is, without a doubt, a key solution to the problem of furniture waste (12 million tons of furniture go to landfills each year in the U.S. alone). Please consider supporting the National Upholstery Association in their efforts to expand professional upholstery education. We need more 'boots on the ground' to do this work. Thank you.
