I think this is a great product and the fact that it is odourless and safety-tested is, in many ways, the best we can expect when you consider how babies will play on it.
For due diligence I wrote Playmatonline to inquire as to some of the safety concerns of the product; as a public service below is the response I got from them.
"Formamide is one of the most commonly used agent when making soft plastic items. Formamide is used during the production of the foam, if it is not precoded properly, formamide will be left in foam and strong ammonia smell. Since all our mats is produces to odourless level and passed European Toy Safety Test EN71 Part, 1, 2, 3, 9, 10 and 11, there should not be any Formamide left.
Regarding about your concern about the product recall in Belgium and France, it is just because there are too many cut cost production playmat with strong ammonia smell and do not pass EN71 test (or ever been tested). So far the European union have not yet set up the standard limit or rules for this contain.
EN 71-1: Mechanical and physical properties
EN 71-2: Flammability
EN 71-3: Specification for migration of certain elements (test for toxic, i.e lead etc)
EN 71-9: Organic chemical compounds - Requirement (test for toxic, i.e ammonia etc)
EN 71-10: Organic chemical compounds - Sample preparation and extraction
EN 71-11: Organic chemical compounds - Methods of analysis
EN 71 Part 1-3 is the basic test for all soft toy product.
EN71 part 9-11 is not normally required for this type of product but we do it just because it is our obligation to provide better PlayMat for parent out there.
