Safbaby has done some amazing research and determined there are two safe playmat companies Edusafe and Tadpole. These were the only two companies who showed their results but others have said they are Formamide free. To cut back further on any off gassing, I’m purchasing one used from ebay.
UPDATE: I should have thought of it but mats are NOT catproof. Ours is already missing small pieces. It is going to be finding a new catfree home.
