Breathable mattress

J❤️
Does anyone have the breathable mattress?? What are your feelings on this? My baby is 5 weeks old and she always had a hard time sleeping and I just learned she prefers sleeping on her belly. I'm a ftm and I'm crazy and nervous that she can suffocate so I want to buy this mattress. It's a pricey tho so I'd like some recommendations on it please!!
