So I’m doing my baby registry and there are like… a million different types of mattresses I can get for my baby’s crib lol

I heard that softer mattresses are unsafe because babies can suffocate in them. So when looking at a mattress, how many coils is good? The one I’m looking at has 80 and very good ratings but I want to know other mom’s opinions.

I am looking at purchasing a new mattress for the bed. I know there are mattresses such as heavenlybed ™ and memory foam such as tempur. Which in your experience, is the best make of mattress for a comfortable night? Serious answers only please.

I’m getting bigger and my old twin bed is a little small now so I want a more comfortable full mattress. I saw a Serta Memory Foam for 300$ which I thought was a really good deal but I don’t know if there’s a better one out there. But I don’t plan on paying more than 350$ or so. If anyone owns a Serta please tell me how they are because I couldn’t find any reviews or ratings. – Thank You
