Hi KathrynP,
Welcome ⦠and Iām glad you found us :).
Iām assuming that youāve read the mattress shopping tutorial which has all the basic information,steps, and guidelines you will need to make the best possible choices ⦠and know how and why to avoid the worst ones.
It may also be worth reading post #2 here which talks about the differences between organic, natural, safe, chemical free, and green materials and mattresses that may help you decide on the type of materials that you are comfortable having in your mattress and help you answer the question of āhow safe is safe enough for me?ā.
There is more about the different levels of organic certifications in post #2 here but certified organic Dunlop that is certified by GOLS (which stands for Global Organic Latex Standard) and is similar to GOTS certification for fabrics is certainly available for those who would prefer it.
Choosing latex that is only made in the US would limit your options considerably because most of the 100% natural Dunlop latex you will find (except for Mountaintop Foam) and all of the organic Dunlop will be manufactured outside of the US. Latex International has 100% natural Talalay that is made in the US but Radium is the other major Talalay manufacturer and also makes 100% natural Talalay but is made in Holland. None of the raw latex itself would come from anywhere in North America and most of it is from Asia or Africa.
There is no consistent definition or standard for a firm mattress between different manufacturers and different people will also have very different definitions or perceptions of what firm feels like to them so your own testing or experience will be the most reliable way to know whether a mattress feels firm to you.
What is available in your budget range would depend on the size of your mattress, the types of materials you are comfortable with, whether your budget is for a āmattress onlyā or includes any accessories you need in addition to your mattress (such as a foundation or bedframe), and on what is available locally or whether you are also comfortable including online manufacturers or retailers in your research.
Choosing a double sided mattress will reduce the number of latex options and the number of designs and features that are available for you to choose from. There is more about the pros and cons of two sided mattresses in post #3 here.
There are certainly mattresses available that only use wool to pass the fire regulations although as you probably know wool is a more costly material. There are also some manufacturers that will make a mattress with no fire barrier at all (wool or otherwise) with a prescription from a licensed health professional. I would keep in mind though that even organic latex has some chemicals in the formulation that are used to foam and manufacture the latex (the GOLS organic certification allows for 5% of āotherā ingredients besides just the natural rubber used to manufacture the foamed latex core). All latex is tested for safety using the same certifications (either Oeko-Tex or Eco-Institut) and by most peopleās standards would be completely āsafeā regardless of whether it is Dunlop or Talalay or made with natural or synthetic rubber or a blend of both but itās not āchemical freeā.
All of these manufacturers use high quality materials and would have no weak links in their design but not all of them use organic latex (if thatās important to you) and some of them may not use organic wool (which again may or may not be important to you based on the information I linked previously). There are certainly advantages to component mattresses because they provide options to customize the mattress both before a purchase (by choosing different firmness levels for the layers) or after a purchase (by rearranging layers or exchanging them) but they also arenāt two sided if thatās an important criteria for you. The tutorial post also includes a list of the members here that sell mattresses online (which includes all of your choices except one) and many of them sell latex mattresses that use different types of latex (including organic) and have a wide range of designs (including two sided), options, features and prices that may also be worth considering ⦠again depending on which of your criteria are most important to you.
