Does anyone know of a comfortable non-toxic mattress that won't make a person with MCS sick? Or the nearest thing? Any help or suggestions would be appreciated. My old mattress makes my body hurt more and thrift store mattresses can't stink worse than new ones!

Thank you!

I'd like to know this also. A surprisingly difficult question to answer unless you have a lot of money to spend.
If you have several thousand dollars to spend, there are certified organic mattresses which should be safe. Also there is a mattress company that was supposedly started by someone with MCS (but who knows really) called My Green Mattress. They have mattresses for slightly under $1000. Since I do not have that kind of money....I can't say how good but I will say: don't buy what I bought! (Read on only if you're considering memory foam or if you have concerns about toxic flame retardants).
This has been a huge challenge in my life as I have recently moved and ditched our mattresses due to mold in house.
I purchased memory foam mattresses (the kind sold on Am@zon and shipped rolled up in a box) due to affordable price (resources exhausted due to living with undiagnosed mold illness for years). Did research and knew that memory foam has a chemical odor but most reports are that the odor goes away when aired out properly, which I did.
In my opinion and in my experience, people with MCS should avoid these memory foam at all costs! I have been made sick by them (migraines, muscle weakness, etc) and even my family members, who up until now were not particularly sensitive, are also getting sick. And don't be fooled by the Certi-Pur foam certification which sounds good and talks about VOC levels but really is just marketing bull. Don't be fooled either by other marketing ploys that imply that the mattress is safe such as "charcoal infused" or "green tea infused".
The off-gassing from foams and adhesives is one thing but when you also consider the chemicals used to make mattresses flame resistant, the problem becomes very complex! I thought I would just replace my toxic mattresses with some "100% cotton" futon style mattresses and live with the back pain until I figure something out. Foam-free and I can't detect an odor, yes, but then I realized that I have no idea what the manufacturer uses to achieve the flame retardant standard. Those chemicals are typically endocrine disruptors and my wife was just diagnosed with Hashimoto's. Neither the retailer or the manufacturer will comment or answer my simple question, nor are they required to.
You asked a great question and I will follow this thread closely for new information. Good luck Kimberly.

the key for me is a mattress cóver because if I take mine (a super thick terry cloth one that by the looks of it belonged to grandma) off then sleeping is impossible, can't even be in the same room

if you could find something similar then I bet the type of mattress wouldn't matter much anymore but I couldn't tell you where to get this kind of quality nowadays..

I bought one from Tuft and Needle that was suppose to have 300 fewer chemicals in it, but I guess foam is foam. What is very cool these days is that, as with Tuft n' Needle, these companies will let you donate the mattress and then refund your money if it doesn't work for you (as long as you get a receipt from the donation place). I am having to do this with the mattress I bought from them. I tried to take the cover off of another mattress and outgas it in the sun etc., but still too stinky. Even when I put a bunch of blankets on top of these mattresses and sleep on them, they make me feel awful.

And, like you said, I don't have a ton of money to spend. I did that once - bought an expensive organic cotton mattress - and it was SO uncomfortable. Waste of money.

Funny that no one has figured out how to sell us canaries a decent mattress!

Thanks for responding . I'll let you know if I find the perfect mattress. I figured that SOMEONE on this site must have found something that works, and it's an important question! (Gotta sleep). But apparently they have all found solutions.

Thanks for your help! Stay strong.

I looked at the "My Green Mattress" site. Doesn't say he had MCS but they push the latex. Have you ever tried a latex mattress or topper? They say it is from "natural rubber" instead of from petroleum (like memory foam), but rubber can be just as nasty to me. But not sure I really know what these latex mattress are like. I'm not allergic to latex (can wear latex gloves) but it must still stink, no?

Just wondering if you (or anyone here) have had any experience with latex. Thanks!
Kimberly

I slept on latex foam as a kid and survived. Yet, I rule it out today after serious consideration and TONS of research. Here's why:
Latex has an odor but totally different than memory foam so probably wouldn't make me sick immediately like memory foam. However, people develop latex allergy which, contrary to popular belief, does not require actual skin contact (breathing the powder is suspect). Also people have found mold growing in their latex foam and mold is enemy #1 in my situation.

Yes Green Mattress seems to promote the foam but they have also a no-foam mattress called Pure Echo. They imply that they use wool to achieve the flammability standard. Anyone less jaded than me would infer that they don't use chemicals/toxins but they never say this explicitly and mattress companies don't seem to want to answer questions from consumers since the recent Purple Mattress scandal.

All things considered, I am thinking the Pure Echo is my best bet. About $700 with no-frills though and I need two so....ouch!
There is also the following mattress from The Futon Shop which explicitly claims to be "chemical-free" but it is more expensive and looks less comfortable to me: Tranquility2 Natural Wool Mattress.
That's my personal short-list at this point. Sadly, a "wish-list" due to $.
If you go with one of these, check for coupon codes, I saw one for 20% off.
If you decide you're maybe okay with latex and you have about $1,800 you could buy a Happsy which has a true no-risk trial and explicitly states "chemical-free".
Good luck!
