Down vs. Down Alternative: Which is Better?

Question from wt

hello, 

i have been looking for a down or down alternative comforter for my two pre-teen boys (this alone, tells you...it's gonna be thrashed in 3-6 months! so i don't want to spend too much money on it. considering it somewhat disposable. ;) 

i, myself, love the wool bedding products from Shepherd's Dream, but i don't want to invest that much money for something so short term for the boys. hence, i'm looking primarily at down alternative comforters. 

are down alternative products considered "acceptable"? or are they BAD in terms of toxins etc. is there one 'brand/type' that is better than the others? or are they all bascially the same things with different names? 

thank you very much.

"Down alternative" is a tricky term because it can mean "an alternative to down," such as cotton or wool or anything else that isn't down, or it can mean a synthetic alternative to down. I think you are asking about the latter. Looking at websites, however, I see all these natural and synthetic choices listed on a "Down Alternatives" page.

The synthetic down alternatives are all made from 100% spun polyester. If the description on a comforter just says "down alternative" and nothing else, it's polyester. They come in different brand names and have slight difference, but they are all basically polyester (I already reviewed one--PrimaLoft--in another question).

Whether or not polyester outgasses and how much it outgasses plasticizers is unknown. It's not high on the list of toxic exposures in comparison to say, pesticides or water pollutants, but it has enough toxicity that I don't recommend it. Plastics are also known to generally weaken the energy field of the body (one researcher found synthetic fibers can cause impotence), so it's probably not the best thing to sleep under. And, of course, there are the environmental effects. Polyester is made from nonrenewable crude oil that often creates pollutants in mining and manufacture. The finished product is also not biodegradable and will sit in a landfill for centuries. So while this product may be convenient to humans, it's not in the best interest of life overall.

Lyocell is a down alternative that is probably a better choice if you don't want to spend the money on natural fill. It is a natural cellulose fabric, like rayon, which is made by processing natural cellulose from birchwood trees with various chemicals. It is considered by some to be an "ecologically friendly fabric". Lyocell is more absorbent than cotton and more comfortable than polyester, as it wicks moisture away from the body and quickly evaporates it into the air (wool does this too) resulting in a more comfortable sleep.
