Does resin treated polyester fiber batting contain formaldehyde?
Probably not. It does depend upon the type of resin used and resin is a very broad term. However, formaldehyde is not a common “resin” ingredient. It is more often found in adhesives foam insulation. Batting is a form of padding. Therefore soft. Formaldehyde is usually found in rigid materials. However, unless the crib is made without pressed fiberboard. That is the crib is solid wood.There is probably formaldehyde present in the binders and glues used to make the wood products. If your daughter’s room is properly ventilated any formaldehyde in any of the crib’s materials will not be at levels that will cause any harm.
