I know many here cosleep, but it is not the right choice for us, for a few factors, including health issues. I hope there are some mothers here that have tried crib mattresses for infants and could advise, because I am a first-time mom. We are debating between a 150 and 252 coil from Naturepedic (the first is "firm enough," the latter would be even firmer). I can't feel them in person, just going to order onilne.
I am leaning towards the firmer one, the 252. However, when reading the reviews, there were just a few people that said their baby just cried on it, and they worry it was the firmness (could have been any number of factors if you ask me, like the waterproof surface feeling too slick, etc). In the reviews for the 150, some people said it was "firm while still being comfortable."
I would rather err on the side of firmer, because I know if the mattress starts to soften I'll worry..... but I am wondering if anyone with actual life experience in this area would steer me away from the firmer of two firms? What are your thoughts/experiences with firm crib mattresses? Anyone whose baby really seemed to hate the ones that are the EXTRA firm? Or is that nonsense, and I'd be amazed at how firm a mattress a baby will sleep on?
So all that to say I'd probably opt for the "standard firm" mattress over the ultra firm mattress since I don't see the structural integrity weakening with normal baby/toddler wear and tear. It is possible that the super firm mattress is uncomfortable for some babies although you're right, that review may have been a fluke. Babies are used to the feel of mom's chest, her arms, her legs, etc so a little softness may feel more comforting and familiar. As long as a mattress is labelled firm, it is safe in terms of reduced SIDS risk as far as I understand. I haven't read anything that suggests extra firm = extra safe so I'd go with the reviews/my instincts on this and get the standard firm mattress. Of course if your intuition is strongly telling you to get the extra firm, trust your gut but inquire about return policies (maybe if you keep the plastic on for a few nights under a crib sheet to see if baby accepts it before unwrapping it completely). Good luck!
I agree with the PP. We got a standard firm mattress and while she sleeps fine in it now, when my daughter was smaller (we started transitioning her at around 3 months) she definitely did not like the firmness. At least in our case, putting her down after she had fallen asleep in the bassinet or in our arms she would immediately wake up in the crib because the mattress was so firm. She's used to it now, but I wouldn't get extra firm just for that reason. As long as the safety is there, extra firmness seems like a liability rather than a benefit.
