Wool is a natural fire retardant material used in many organic mattresses. It is generally free of fire retardant chemicals. “Organic” wool, taken from “organically” raised sheep, is especially pure as the sheep are raised on organic feed with special care taken to ensure their humane treatment. However, most wool used by organic mattress manufacturers is actually not organic.
In adult sized mattresses, wool is an excellent, natural, and luxurious fire retardant material. However, its use in baby products is questionable. A precautionary approach should be taken since babies are potentially susceptible to high allergy materials such as wool and other animal hairs.
Wool has long been associated with allergies, particularly in children. For example, wool intrinsically contains lanolin and certain alcohols known to have allergenic properties. Other allergens originate not with the wool itself, but with the chemical treatments applied (in order to clean it from dirt, sand, grease and dried sweat).
Naturepedic baby products strive to be as non-allergenic as possible and, as such, do not contain any wool.
