Turns out you'll need a doctor's prescription to even order a plain cotton mattress. Yet another perfectly reasonable regulation from our friends in the California Legislature! :)
My least-favorite CA regulation has to do with eye-glasses. I lost my only pair and went in to get a replacement on a Saturday, but I couldn't because my (perfectly fine) prescription had expired. I had to make an appointment to get an exam in order to get new glasses, but they were closed for the weekend and booked for a few days.
So I spent about a week with headaches because some CA legislator decided it was in my best interest to pay some practitioner to get the same prescription for glasses every year.
If you know what your prescription is, you could order online from a place like Zenni Optical (where my wife gets her glasses). I'm not sure about PA, but here in PA, it's illegal for an optometrist to withold information about your prescription. She got her eyes checked, had to push a little to get her prescription, and then bought her glasses online.

Alternatively, you can order one of the cotton/latex/wool mattresses that don't have any flame retardents. The most popular is Naturepedic. However, such a mattress will set you back $2200 for the most basic queen.
