Even though they are very small, they have an extreme strong Formaldehyde smell. Formaldehyde causes cancer and I don't understand why Mayfair is not establishing a standard requiring furniture producers to use non-toxic glues as this is a standard in Europe. I have put them in front of an open window now for 3 days and it is still not suitable to put it into the bedroom unless someone wants to get poisoned over night and at a minimum wakes up with a headache and lung pain.
