Hi JMHK,
I switched your post to a new topic of its own so our conversation doesn’t get mixed in with another member’s topic and questions.
The first step in finding a “safe” or chemical free" mattress would be to decide on the specific types of materials that you would be comfortable with having in her mattress. There is more information in post #2 here and the more detailed posts and information it links to about safe, natural, organic, “chemical free”, and “green” mattresses and mattress materials that can help you sort through some of the marketing information and terminology that you will encounter in the industry and can help you differentiate between them and answer “how safe is safe enough for me” or “how natural is natural enough for me” so you can decide on the types of materials you are most comfortable having in your mattress so you can focus on the materials in a mattress rather than the name of a manufacturer that makes it. These types of issues can be complex and are generally specific to each person and their individual sensitivities, circumstances, criteria, beliefs, and lifestyle choices.
I’m not sure where you are in central New Jersey but post #7 here includes the better options or possibilities I’m aware of in the region around Monroe Township (subject to the quality/value guidelines here). If none of these are close to you then if you can let me know your city or zip code I can link you to the forum list that is closest to you.
If you are also open to an online purchase then the tutorial also includes a link to a list of the members here that sell mattresses online (in the optional online step) and many of these also sell mattresses that by most people’s definition would be considered to be “chemical free” and use “safe” or natural or in some cases organic materials.
