Hi Be.moody,
Unfortunately it’s easy to do with the lack of information about mattresses and mattress materials that is generally available to consumers.
The first place I would start your research is the mattress shopping tutorial here which has all the basic information, steps, and guidelines that can help you make the best possible choice … and know how and why to avoid the worst ones.
If you let me know your city or zip code I’d also be happy to let you know about any of the better options or possibilities I’m aware of in your area.
