This is a fantastic informative site and I have spent many hours reading through all the information - thank you. I am looking for a natural filled mattress that contains the least amount of fire retardant chemicals and VCOs. Are you able to give a rough percentage amount for each of your mattresses or rank them in order? I also read a question from about a year ago about the need for treated top fabrics. I have noticed a few manufactures now stating their outer fabric is chemical free. Is this something you will be able to offer in the near future?
