I had my first child six years ago. The mini crib mattress I had bought at the time was now discontinued. So, I had to begin a new search for a company that made a non-toxic, non-off-gassing, naturally flame retardant mattress that fit into my mini crib. I was very surprised to find that this was no easy task! I found that many mattresses came close, but I only found 1 that checkmarked all 3 boxes. My beautiful mattress came quickly and just as described. I am very happy with my purchase.
