Serious question: I haven't bought a mattress in WHILE. I'm talking like at least 10 years. All these new foams and gels everyone is talking about...I'm kind of old fashioned, and something I think about every time I open this thread is: aren't all these new mattresses extremely flammable? Pretty much everything I own in my home is 'real' - Wood, Metal, Glass, Cotton, Wool, etc.. I love a rock hard mattress, personally, but I'll be buying this spring for my 85-year-old Mom, as well as my fiancée and step-son. Have learned a lot here about many important factors in buying a mattress, and thanks to everyone for the info. Putting comfort and everything else aside though, what's available in mattresses these days if I don't want to get immolated in seconds or have my mattress melt to me in a searing burst of some synthetic material, if there was an emergency involving a fire? Anything still made the old fashioned way with 'real' materials, and of the highest quality? I'm not very concerned with how much I spend. Does what I'm talking about even exist? TIA.
