Here are some other thoughts I've had surrounding this issue:
A lot of car seat manufacturers claim to have phased out flame retardants chemicals (and other chemicals like lead, PVC, pthalates, etc) but parents began taking samples of their children's car seats and sending them to the lab for testing and the supposed non-existent chemicals were still there...and not in low amounts. The companies that seem the most dishonest will be the ones least likely to get my money.
The Mattress Underground has more information on latex/organic mattresses than I've found anywhere else. There's a forum where you can read other people's journeys and ask questions - in particular, I searched for "children's mattresses" and found a lot of great advice.
Many latex mattress store owners are members of the site and offer discounts to fellow members.
As for sofas, I put my nasty Ikea sofa on Craigslist and sold it within a few days and the very next day, I found a mission style quarter-sawn oak sofa and chair for *excatly* the same amount of money I sold our sofa & loveseat for. I snatched it up with the intention of replacing the petroleum foam cushion with natural latex (something I still need to do...) I'll share a photo at the end of this post.
As for other baby gear, including strollers and wagons, many (most) are also drenched in flame retardants (and lead.) I have no idea why a stroller or wagon would "need" flame retardants, but there ya go. Nursing pillows like Boppy, baby carriers, high chairs, changing pads, bouncy seats, ALL of this stuff, is treated with chemical flame retardants. I'll share some links to sites where I found useful information like which companies do not use chemical flame retardants. I know that BOB and Mountain Buggy strollers aren't treated, and other Britax strollers. Baby Trend is one of the worst strollers for flame retardants.
In the house, sofas, any type of petroleum-based foam (or soy foam), drapes, mattresses, pillows, wall-to-wall carpeting, and electronics are treated with chemical flame retardants. Some electronics are "safer" than others; I think maybe Sony is one company who has decided to use less/safer chemicals.
Dust is the biggest factor for absorbing flame retardant chemicals, topically and through inhalation/orally. Babies and young children are at the highest risk because they're usually on the floor and putting objects and hands in their mouths. So vacuuming with a HEPA filter and damp-wiping dust frequently is helpful (in the car too.) Of course, the less furnishings you have that contain chemicals, the less there will be in your household dust.
And FINALLY, I clearly remember my anxiety levels reaching their peak sometimes shortly after my firstborn's first birthday because I was completely overwhelmed by all of the "hidden dangers" of our world that I was suddenly very aware of. How was I going to protect this precious child of mine when everything around us was toxic and dangerous?! I'm not sure what advice I'd offer to first-time parents about this potential for freaking out other than, it gets easier. You do the best that you can, make the best choices with what you know, and be pro-active about keeping their little growing bodies as healthy as possible and remember we're all just specks in the Universe.
